Calves have been identified in numerous reports as a major source of environmental contamination with this pathogen. Parasite has a different species that are the cases of zoonotic disease in immunodeficient people and neonatal calves. Cryptosporidium oocysts are extremely resistant to chlorine and other physical cases that commonly used in drinking water. Reproduction of resistant oocytes is a way for this monoxenous parasite to remain in the environment. Cryptosporidium parvum is the most important species that has human and cattle genotypes. Cryptosporidium is one of the most important causes of diarrhea in neonatal calves and also, one of the four causes of diarrhea symptoms in pre-weaned calves. Because of the incompetent immune system in calves, Cryptosporidium infection is the cause of a lot of problems in raising farms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cryptosporidium%20spp" title="Cryptosporidium spp">Cryptosporidium spp</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy%20calves" title=" dairy calves"> dairy calves</a>, <a href="https://publications.waset.org/abstracts/search?q=importance" title=" importance"> importance</a>, <a href="https://publications.waset.org/abstracts/search?q=veterinary%20medicine" title=" veterinary medicine"> veterinary medicine</a> </p> <a href="https://publications.waset.org/abstracts/5549/importance-of-cryptosporidiosis-in-dairy-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">583</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> The Effects on Abomasal Emtying Rate of Erythromycin and Bethanechol in Healthy, Premature and Diarrheic Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sebnem%20Canikli%20Engin">Sebnem Canikli Engin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mutlu%20Sevinc"> Mutlu Sevinc</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Guzelbektes"> Hasan Guzelbektes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we aim to define the effects of erythromycin and bethanechol which are prokinetic agents, on the value of abomasal discharge in healthy, diarrhea and premature calves. In the work, 5 healty calves, 12 diarrheaic calves and 12 premature calves, amounting to a total of 29 calves. In healty calves work; the same 5 calves were used for controlled, erythromycin and bethanechol studies (there was a 48-hour waiting period between each work). In diarrheic calves work; 12 diarrheic calves were used during the study (4 of them for control group, 4 of them bethanechol group and last 4 calves erythromycin group). In premature calves works; 12 premature calves were used during the study (4 of them for control group, 4 of them bethanechol group and last 4 calves erythromycin group). 10 mg/kg IM dose of erythromycin were applied to each erythromycin group, 0,07 mg/kg IM dose of bethanechol were applied on bethanechol group. No drugs were applied to the control group and substitution milk was given to all calves. 50 mg/kg acetominophen and 25 gram/L glucose have been added into the substitution milk to evaluate the speed of gastrointestinal motility with the test results of absorptions of acetominophen and glucose. The blood samples have been taken before substitution milk application and 30, 60, 90, 120, 180, 240 and 300 minutes after substitution milk application. Respiratory rates and number of heartbeats were also recorded during the test time. No changes were observed in the number of heartbeats, respiratory rates and general conditions for all groups after drug application. It is observed that, the feces of some calves became slightly watery and viscous and premature calves generaly defecated after 180 minutes. When Cmax, Tmax and AUC values of acetaminophen and glucose are compared with control group’s after applying erythromycin on the calves in the premature group, we obtain higher Cmax (P<0,05), shorter Tmax and greather AUC (P>0,05) values. In conclusion, according to clinical and laboratory findings, it may be stated that the application of 10 mg/kg doze of erythromycin IM has provided faster abomazal emptying in premature calves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abomazal%20emptying" title="abomazal emptying">abomazal emptying</a>, <a href="https://publications.waset.org/abstracts/search?q=bethanechol" title=" bethanechol"> bethanechol</a>, <a href="https://publications.waset.org/abstracts/search?q=calf" title=" calf"> calf</a>, <a href="https://publications.waset.org/abstracts/search?q=erythromycin" title=" erythromycin"> erythromycin</a> </p> <a href="https://publications.waset.org/abstracts/43802/the-effects-on-abomasal-emtying-rate-of-erythromycin-and-bethanechol-in-healthy-premature-and-diarrheic-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43802.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">337</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Comparison of Serum Protein Fraction between Healthy and Diarrhea Calf by Electrophoretogram</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jinhee%20Kang">Jinhee Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwangman%20Park"> Kwangman Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruhee%20Song"> Ruhee Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Suhee%20Kim"> Suhee Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Do-Hyeon%20Yu"> Do-Hyeon Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoungseong%20Choi"> Kyoungseong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinho%20Park"> Jinho Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Statement of the Problem: Animal blood components maintain homeostasis when animals are healthy, and changes in chemical composition of the blood and body fluids can be observed if animals have a disease. In particular, newborn calves are susceptible to disease and therefore hematologic tests and serum chemistry tests could become an important guideline to the diagnosis and the treatment of diseases. Diarrhea in newborn calves is the most damaging to cattle ranch, whether dairy or cattle fattening, and is a large part of calf atrophy and death. However, since the study on calf electrophoresis was not carried out, a survey analysis was conducted on it. Methodology and Theoretical Orientation: The calves were divided into healthy calves and disease (diarrhea) calves, and calves were classified by 1-14d, 15-28d, and more than 28d, respectively. The fecal state was classified by solid (0-value), semi-solid (1-value), loose (2-value) and watery (3-value). In the solid (0-value) and semi-solid (1-value) feces valuable pathogen was not detected, but loose (2-value) and watery (3-value) feces were detected. Findings: ALB, α-1, α-2, α-SUM, β and γ (Gamma) were examined by electrophoresis analysis of healthy calves and diarrhea calves. Test results showed that there were age differences between healthy calves and diarrheic calves. When we look at the γ-globulin at 1-14 days of age, we can see that the average calf of healthy calves is 16.8% and the average of diarrheal calves is 7.7%, when we look at the figures for the α-2 at 1-14 days, we found that healthy calves average 5.2% and diarrheal calves 8.7% higher than healthy cows. On α-1, 15-28 days, and after 28 days, healthy calves average 10.4% and diarrheal calves average 7.5% diarrhea calves were 12.6% and 12.4% higher than healthy calves. In the α-SUM, the healthy calves were 21.6%, 16.8%, and 14.5%, respectively, after 1-14 days, 15-28 days and 28 days. diarrheal calves were 23.1%, 19.5%, and 19.8%. Conclusion and Significance: In this study, we examined the electrophoresis results of healthy calves and diseased (diarrhea) calves, gamma globulin at 1-14 days of age were lower than those of healthy calves (diarrhea), indicating that the calf was unable to consume colostrum from the mother when it was a new calf. α-1, α-2, α-SUM may be associated with an acute inflammatory response as a result of increased levels of calves with diarrhea (diarrhea). Further research is needed to investigate the effects of acute inflammatory responses on additional calf-forming proteins. Information on the results of the electrophoresis test will be provided where necessary according to the item. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alpha" title="alpha">alpha</a>, <a href="https://publications.waset.org/abstracts/search?q=electrophoretogram" title=" electrophoretogram"> electrophoretogram</a>, <a href="https://publications.waset.org/abstracts/search?q=serum%20protein" title=" serum protein"> serum protein</a>, <a href="https://publications.waset.org/abstracts/search?q=%CE%B3" title=" γ"> γ</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma" title=" gamma"> gamma</a> </p> <a href="https://publications.waset.org/abstracts/102458/comparison-of-serum-protein-fraction-between-healthy-and-diarrhea-calf-by-electrophoretogram" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102458.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Growth Performance of New Born Holstein Calves Supplemented with Garlic (Allium sativum) Powder and Probiotics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20W.%20Kekana">T.

This study was carried out to investigate the effects of feeding Garlic powder or probiotics or a combination of both on feed intake and growth performance of Holstein calves. Neonatal calves were randomly allocated, according to birth weight, to four dietary treatments, each with 8 calves. The treatments were: C control, no additive (C), G: supplemented with either 5g/d garlic powder (G) or 4 g/d probiotics (P) or GP 5g/d garlic powder and 4 g/d probiotics compound (GP) with the total viable count of 1.3 x 107 cfu/g. Garlic and probiotics were diluted in the daily milk allocation from day 4. Commercial (17.5% CP) starter feed and fresh water were available ad libitum from day 4 until day 42 of age. Calves fed GP (0.27 kg day-1) tended (P=0.055) to have higher DMI than C (0.22 kg day-1). Milk, water, CP, fat intake and FCR were not affected (P>0.05) by the treatments. Metibolisable energy (ME) intake for GP group tended (P=0.058) to be higher than C calves. Combination of G and P (60.3 kg) tended (P = 0.056) to be higher than C (56.0 kg) calves on final BW. Garlic, probiotics or their combination did not affect calve’s HG, ADG and BL (P>0.05). The results of the current study indicated that combination of garlic and probiotics may improve nutrients intake and body weight when fed to calves during the first 42 days of life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=garlic%20powder" title="garlic powder">garlic powder</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotics" title=" probiotics"> probiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=intake" title=" intake"> intake</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=Holstein%20calves" title=" Holstein calves"> Holstein calves</a> </p> <a href="https://publications.waset.org/abstracts/14153/growth-performance-of-new-born-holstein-calves-supplemented-with-garlic-allium-sativum-powder-and-probiotics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14153.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">671</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Effect of Chromium Yeast on Hematological Parameters in Camel Calves (Camelus dromedaries) Reared under Hot Summer Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Ahmed%20Abdoun">Khalid Ahmed Abdoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdulwahid%20Alsoufi"> Mohamed Abdulwahid Alsoufi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Abdullah%20Alhidary"> Ibrahim Abdullah Alhidary</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The intention of this study was to evaluate the effect of dietary Cr supplementation on haematological parameters in camel calves reared under hot summer conditions. Fifteen male camel calves (5 – 6 months old) were randomly allotted to three dietary treatments (n = 5) for a period of 84 days. Camel calves were fed ad libitum on basal diet without Cr supplementation (control), basal diet supplemented with 0.5 mg Cr/kg DM (Cr 0.5) or basal diet supplemented with 1.0 mg Cr/kg DM (Cr 1.0). During this, blood samples were collected every four weeks for hematological examination. The obtained results revealed that dietary Cr supplementation to camel calves reared under hot summer did not show significant effects (P> 0.05) on hematological variables. However, the neutrophil to lymphocytes ratio (N: L ratio) was significantly (P < 0.05) reduced in camel calves fed on diets supplemented with chromium. In conclusion, Chromium supplementation to the diet of camel calves did not show any significant effects on hematological variables. Whereas, the neutrophil to lymphocytes ratio (N: L ratio) was reduced in camel calves fed diets supplemented with chromium. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=camel%20calves" title="camel calves">camel calves</a>, <a href="https://publications.waset.org/abstracts/search?q=chromium" title=" chromium"> chromium</a>, <a href="https://publications.waset.org/abstracts/search?q=haematological" title=" haematological"> haematological</a>, <a href="https://publications.waset.org/abstracts/search?q=immune%20response" title=" immune response"> immune response</a> </p> <a href="https://publications.waset.org/abstracts/48428/effect-of-chromium-yeast-on-hematological-parameters-in-camel-calves-camelus-dromedaries-reared-under-hot-summer-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48428.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">278</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Determination of Some Etiologic Agents in Calves with Diarrhea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nermin%20Isik">Nermin Isik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozlem%20Derinbay%20Ekici"> Ozlem Derinbay Ekici</a>, <a href="https://publications.waset.org/abstracts/search?q=Oguzhan%20Avci"> Oguzhan Avci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to determination of role infection in neonatal calves in Central Anatolian, Turkey. A total 300 fecal samples were collected from diarrheic neonatal calves, aged between 0–90 days from Konya, Karaman, and Aksaray from January to April 2014. Fecal specimens from calves with clinically diarrheic symptoms were examined for the presence of Bovine Coronavirus, Bovine Rotavirus, Cryptosporidium sp., and E. coli by commercially available capture direct enzyme linked immunosorbent assay (ELISA) kit and Modified Ziehl Neelsen method (MZN). Calves were grouped according to their age as follows: 1-14, 15-29, and 30-90 days. Cryptosporidium sp. infection was detected in 52.8%, 58.8%, and 39.2% by ELISA and 33.9%, 47%, 26.7% by MZN in the respective age groups. The seroprevalance of Rotavirus (12.5 %, 40 %, 12.5 %), Coronavirus (2.5%, 0%, 3.5%) and E. coli (5%, 4.7%, 8.9%) infections were determined according to the age groups respectively. Cryptosporidium sp. was the most detected enteropathogen (52 %) of calves and coronavirus was the least detected (2 %). The detection rate of the mixed enfection was 12.3%.

The aim of this study was to determine the prevalence of Eimeria spp. in calves in Konya, in Turkey. The study, conducted from January- February 2015, involved 240 faecal samples of calves in the age groups of <1 month, 1-3 months and >3 months in Konya city centre, in Turkey. In a retrospective study from these faecal samples of calves submitted to the University of Selcuk, Faculty of Veterinary Medicine, Laboratory of Parasitology were evaluated regarding the prevalence of Eimeria spp. Faecal samples were examined by Fulleborn saturated salt floatation technique. Eimeria oocysts were found in 8.33% of all samples. The positivity rates in each of the age groups were different. According to the age groups (<1 month, 1-3 months and >3 months), the Eimeria spp. were determined as 0.83, 22.73 and 7.41%, respectively. After examination of stool, detected oocysts were sporulated in 2.5% potassium dichromate at 22º C and species were identified as E. cylindrica, E. zuernii, E. ellipsoidalis, E. subspherica, E. bovis, E. auburnensis, E. canadensis, E. illinoisensis and E. brasiliensis in infected calves. In conclusion, the highest prevalence was observed in the age group of 1-3 months. The presence of Eimeria species in calves demonstrated for the first time in the Konya region in Turkey. Other etiologic agents should also be investigated in calves more seriously. Further molecular epidemiological studies should be performed in this community. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eimeria%20spp." title="Eimeria spp.">Eimeria spp.</a>, <a href="https://publications.waset.org/abstracts/search?q=calves" title=" calves"> calves</a>, <a href="https://publications.waset.org/abstracts/search?q=diarrhea" title=" diarrhea"> diarrhea</a>, <a href="https://publications.waset.org/abstracts/search?q=bovine%20coccidiosis" title=" bovine coccidiosis"> bovine coccidiosis</a> </p> <a href="https://publications.waset.org/abstracts/27519/eimeria-spp-in-naturally-infected-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27519.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">537</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Clinical Signs of Neonatal Calves in Experimental Colisepticemia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samad%20Lotfollahzadeh">Samad Lotfollahzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Escherichia coli (E.coli) is the most isolated bacteria from blood circulation of septicemic calves. Given the prevalence of septicemia in animals and its economic importance in veterinary practice, better understanding of changes in clinical signs following disease, may contribute to early detection of the disorder. The present study has been carried out to detect changes of clinical signs in induced sepsis in calves with E.coli. Colisepticemia has been induced in 10 twenty-day old healthy Holstein- Frisian calves with intravenous injection of 1.5 X 109 colony forming units (cfu) of O111: H8 strain of E.coli. Clinical signs including rectal temperature, heart rate, respiratory rate, shock, appetite, sucking reflex, feces consistency, general behavior, dehydration and standing ability were recorded in experimental calves during 24 hours after induction of colisepticemia. Blood culture was also carried out from calves four times during the experiment. ANOVA with repeated measure is used to see changes of calves’ clinical signs to experimental colisepticemia, and values of P≤ 0.05 was considered statistically significant. Mean values of rectal temperature and heart rate as well as median values of respiratory rate, appetite, suckling reflex, standing ability and feces consistency of experimental calves increased significantly during the study (P<0.05). In the present study, median value of shock score was not significantly increased in experimental calves (P> 0.05). The results of present study showed that total score of clinical signs in calves with experimental colisepticemia increased significantly, although the score of some clinical signs such as shock did not change significantly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calves" title="calves">calves</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20signs%20scoring" title=" clinical signs scoring"> clinical signs scoring</a>, <a href="https://publications.waset.org/abstracts/search?q=E.%20coli%20O111%3AH8" title=" E. coli O111:H8"> E. coli O111:H8</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20colisepticemia" title=" experimental colisepticemia"> experimental colisepticemia</a> </p> <a href="https://publications.waset.org/abstracts/37741/clinical-signs-of-neonatal-calves-in-experimental-colisepticemia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37741.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">376</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Effect of an Oral Dose of M. elsdenii NCIMB 41125 on Lower Digestive Tract, Bacteria Count and Rumen Fermentation in Holstein Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20C.%20Muya">M.

The first groups were dosed with 50 ml containing 108 CFU/mL of M. elsdenii NCIMB 41125 (Me) and the control calves were not dosed. Within each of the two treatments groups, calves were divided into three treatment groups (Not dosed: 7 d, 14 d and 21 d vs dosed Me 7 d, Me14 and Me21 d (treatments), each groups contained 4 calves within which two calves were euthanized at 24 h and two calves at 72 h. Calves entered the trial until euthanize at whether 24 or 72 H after dosing time. After receiving colostrum for 3 consecutive days after birth, calves were fed whole milk and had free access to a commercial calf starter pellet and fresh water. Fecal grab samples were taken from each calf in duplicate +24 h or +72 h relative to dosing. Immediately after euthanizing, the digestive tract was harvested, and duplicate rumen and colon digesta samples collected for VFA’s determination and DNA extraction for bacteria count using 16s RNA PCR probe technique. Independent two t-test was performed to compare mean volatile fatty acids. Mixed-effects linear regressions were performed to establish relationships between: 1) M. elsdenii and Me, and between VFA’s and Me using SAS (2009). M. elsdenii NCIMB 41125 was detected in the faeces, colon and rumen of dosed calves at both +24H and +72H and ranged from 1.6 x 106 to 4.9 x 109 cfu/ml, indicating its potential to colonize in the digestive tract of calves. There was a strong positive relationship (R²=0.96; P < 0.0001) between M. elsdenii NCIMB 41125 and M. elsdenii population (cfu/ml) in the rumen, suggesting that the increase in M. elsdenii was due to increased M. elsdenii NCIMB 41125. An increase in butyrate was observed from +24 h to +72 h when calves were dosed on both d 7 and 14. Results showed that Me presented a positive relationship with butyrate (P < 0.001, R² = 0.43) and a concomitant negative relationship with acetate (P = 0.017, R² = -0.33). These results suggest that dosing pre-weaned dairy calves with M. elsdenii NCIMB 41125 has the potential to alter ruminal VFA production through increasing proportions of butyrate at the expense of propionate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calves" title="calves">calves</a>, <a href="https://publications.waset.org/abstracts/search?q=megasphaera%20elsdenii" title=" megasphaera elsdenii"> megasphaera elsdenii</a>, <a href="https://publications.waset.org/abstracts/search?q=rumen%20fermentation" title=" rumen fermentation"> rumen fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteria" title=" bacteria"> bacteria</a> </p> <a href="https://publications.waset.org/abstracts/37345/effect-of-an-oral-dose-of-m-elsdenii-ncimb-41125-on-lower-digestive-tract-bacteria-count-and-rumen-fermentation-in-holstein-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37345.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">394</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Genetics of Birth and Weaning Weight of Holstein, Friesians in Sudan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Safa%20A.%20Mohammed%20Ali">Safa A.

Kucinskas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In calves less than 10-day-old, infection commonly cause severe diarrhoea and high mortality. To prevention of calves diseases a common practice is to treat calves with prophylactic antibiotics, in this case the use of lactic acid bacteria (LAB) is promising. Often LAB strains are incubated in comercial de Man-Rogosa-Sharpe (MRS) medium, the culture are centrifuged, the cells are washing with sterile water, and this suspension is used as a starter culture for animal health care. Juice of potatoe tubers is industrial wastes, wich may constitute a source of digestible nutrients for microorganisms. In our study the ability of LAB to utilize potatoe tubers juice in cell synthesis without external nutrient supplement was investigated, and the influence of multiplied LAB on calves blood parameters was evaluated. Calves were selected based on the analogy principle (treatment group (n=6), control group (n=8)). For the treatment group 14 days was given a 50 ml of fermented potatoe tubers juice containing 9.6 log10 cfu/ml of LAB. Blood parameters (gas and biochemical) were assessed by use of an auto-analyzers (Hitachi 705 and EPOC). Before the experiment, blood pH of treatment group calves was 7.33, control – 7.36, whereas, after 14 days, 7.28 and 7.36, respectively. Calves blood pH in the treatment group remained stable over the all experiment period. Concentration of PCO2 in control calves group blood increased from 63.95 to 70.93, whereas, in the treatment group decreased from 63.08 to 60.71. Concentration of lactate in the treatment group decreased from 3.20 mmol/l to 2.64 mmol/l, whereas, in control - increased from 3.95 mmol/l to 4.29 mmol/l. Concentration of AST in the control calves group increased from 50.18 IU/L to 58.9 IU/L, whereas, in treatment group decreased from 49.82 IU/L to 33.1 IU/L. We conclude that the 50 ml of fermented potatoe tubers juice containing 9.6 log10 cfu/ml of LAB per day, by using 14 days, reduced risk of developing acidosis (stabilizes blood pH (p < 0.05)), reduces lactates and PCO2 concentration (p < 0.05) and risk of liver lesions (reduces AST concentration (p < 0.005)) in blood of calves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20substrate" title="alternative substrate">alternative substrate</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20parameters" title=" blood parameters"> blood parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=calves" title=" calves"> calves</a>, <a href="https://publications.waset.org/abstracts/search?q=lactic%20acid%20bacteria" title=" lactic acid bacteria"> lactic acid bacteria</a> </p> <a href="https://publications.waset.org/abstracts/24269/the-influence-of-bacteriocins-producing-lactic-acid-bacteria-multiplied-in-an-alternative-substrate-on-calves-blood-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24269.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">313</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Effect of Parenteral Administration of Vitamin A in Pregnant Dry Cows, on Vitamin A Status of Neonatal Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samad%20Lotfollahzadeh">Samad Lotfollahzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To evaluate the effect of intramuscular administration of vitamin A during dry period in pregnant dairy cows, which already received it in their daily ration, on vitamin A status of neonatal calves, a total of 30 cows were randomly selected and divided to two main groups; treatment and control group. Animals in the treatment group were subdivided into two groups. Single intramuscular injection of 2000000 IU vitamin A; was carried in 10 dairy cows at 7 months of pregnancy (group 1). In the second group of treated animals (10 cows) the injection was performed in 8 months of pregnancy (group 2). Ten pregnant dairy cows were received saline injection as placebo and selected as the control group. Blood samples were collected from experimental dairy cows at 7 and 8 months of pregnancy as well as their newborn calves’ pre and after colostrum intake. There was no significant difference between vitamin A and β- carotene concentration of dairy cows of three groups in two last months of pregnancy (P > 0.05). Vitamin A concentration of calves of two treatment groups before and after receiving of colostrum were significantly higher than that in the control group (P < 0.05). There was no significant difference between serum concentrations of vitamin A in calves of two treated groups (P > 0.05). β- Carotene concentration of serum samples of dairy cows and neonatal calves of three groups were not significantly different as compared with together. From results of the present study it can be concluded that daily supplementation of vitamin A in late pregnancy in dairy cows may not compensate the calves need for vitamin A and single injection of this vitamin A during dry either in 7 or 8 months of pregnancy can significantly increase level of vitamin A in their colostrum and neonatal calves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dry%20cow" title="dry cow">dry cow</a>, <a href="https://publications.waset.org/abstracts/search?q=beta%20carotene" title=" beta carotene"> beta carotene</a>, <a href="https://publications.waset.org/abstracts/search?q=newborn%20calves" title=" newborn calves"> newborn calves</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20A" title=" vitamin A"> vitamin A</a>, <a href="https://publications.waset.org/abstracts/search?q=dry%20cows" title=" dry cows"> dry cows</a> </p> <a href="https://publications.waset.org/abstracts/37739/effect-of-parenteral-administration-of-vitamin-a-in-pregnant-dry-cows-on-vitamin-a-status-of-neonatal-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37739.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">376</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Blood Analysis of Diarrheal Calves Using Portable Blood Analyzer: Analysis of Calves by Age</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwangman%20Park">Kwangman Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinhee%20Kang"> Jinhee Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Suhee%20Kim"> Suhee Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Dohyeon%20Yu"> Dohyeon Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoungseong%20Choi"> Kyoungseong Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinho%20Park"> Jinho Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Statement of the Problem: Diarrhea is a major cause of death in young calves. This causes great economic damage to the livestock industry. These diarrhea cause dehydration, decrease blood flow, lower the pH and degrade enzyme function. In the past, serum screening was not possible in the field. However, now with the spread of portable serum testing devices, it is now possible to conduct tests directly on field. Thus, accurate serological changes can be identified and used in the field of large animals. Methodology and Theoretical Orientation: The test groups were calves from 1 to 44 days old. The status of the feces was divided into four grade to determine the severity of diarrhea (grade 0,1,2,3). Grade 0, 1 is considered to have no diarrhea. Grade 2, 3 is considered to diarrhea positive group. One or more viruses were detected in this group. Diarrhea negasitive group consisted of 57 calves (Asan=30, Samrye=27). Diarrhea positive group consisted of 34 calves (Kimje=27, Geochang=7). The feces of all calves were analyzed by PCR Test. Blood sample was measured using an automatic blood analyzer(i-STAT, Abbott inc. Illinois, US). Calves were divided into 3 groups according to age. Group 1 is 1 to 14 days old. Group 2 is 15 to 28 days old. Group 3 is more than 28 days old. Findings: Diarrhea caused an increase in HCT due to dehydration. The difference from normal was highest in 15 to 28 days old (p < 0.01). At all ages, bicarbonate decreased compared to normal, and therefore pH decreased. Similar to HCT, the largest difference was observed between 15 and 28 days (p < 0.01). The pCO₂ decreases to compensate for the decrease in pH. Conclusion and Significance: At all ages, HCT increases, and bicarbonate, pH, and pCO₂ decrease in diarrhea calves. The calf from 15 days to 28 days shows the most difference from normal. Over 28 days of age, weight gain and homeostasis ability increase, diarrhea is seen in the stool, there are fewer hematologic changes than groups below 28 days of age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calves" title="calves">calves</a>, <a href="https://publications.waset.org/abstracts/search?q=diarrhea" title=" diarrhea"> diarrhea</a>, <a href="https://publications.waset.org/abstracts/search?q=hematological%20changes" title=" hematological changes"> hematological changes</a>, <a href="https://publications.waset.org/abstracts/search?q=i-STAT" title=" i-STAT"> i-STAT</a> </p> <a href="https://publications.waset.org/abstracts/102455/blood-analysis-of-diarrheal-calves-using-portable-blood-analyzer-analysis-of-calves-by-age" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102455.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Anatomical and Pathological Evaluation of Anomaly Cases Presented to the Department of Pathology at the Kafkas University Faculty of Veterinary Medicine, between 2017 and 2019</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G%C3%BClseren%20K%C4%B1rba%C5%9F%20Do%C4%9Fan">Gülseren Kırbaş Doğan</a>, <a href="https://publications.waset.org/abstracts/search?q=Emin%20Karakurt"> Emin Karakurt</a>, <a href="https://publications.waset.org/abstracts/search?q=Mushap%20Kuru"> Mushap Kuru</a>, <a href="https://publications.waset.org/abstracts/search?q=Hilmi%20Nuho%C4%9Flu"> Hilmi Nuhoğlu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Developmental anomalies can be caused by defects in bone tissue, cartilage tissue, or primitive mesenchymal tissue. Genetic-, environmental-, teratogenic-, faulty breeding selection–, or feeding-related anomalies can be observed either locally or systemically. This study aimed to evaluate in detail the various anomalies in six calves according to pathological and anatomical investigations. Six calves were delivered to the Department of Pathology at the Kafkas University Faculty of Veterinary Medicine between 2017 and 2019. These calves comprised one with anencephaly, one with the diencephalic syndrome, one with Schistosoma reflexum, two with anasarca, and one with nasal and calvarium openings. After necropsy, samples were taken from the organs, foreseen, and routine pathological examinations were performed. Following these procedures, the calves were brought to the anatomy laboratory and anatomically examined. As a result, various anomalies in 6 calves were evaluated according to pathological and anatomical investigations. These findings are believed to contribute to the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anatomy" title="anatomy">anatomy</a>, <a href="https://publications.waset.org/abstracts/search?q=anomaly" title=" anomaly"> anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=calf" title=" calf"> calf</a>, <a href="https://publications.waset.org/abstracts/search?q=pathology" title=" pathology"> pathology</a> </p> <a href="https://publications.waset.org/abstracts/110508/anatomical-and-pathological-evaluation-of-anomaly-cases-presented-to-the-department-of-pathology-at-the-kafkas-university-faculty-of-veterinary-medicine-between-2017-and-2019" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110508.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Effects of Ig Y Supplementation to Colostrum Having Insufficient Antibodies on Calves Metabolism and Costs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cangir%20Uyarlar">Cangir Uyarlar</a>, <a href="https://publications.waset.org/abstracts/search?q=Eyup%20Eren%20Gultepe"> Eyup Eren Gultepe</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Kabu"> Mustafa Kabu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hac%C4%B1%20Ahmet%20Celik"> Hacı Ahmet Celik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to evaluate the effects of orally Immunoglobulin (Ig) Y treatments to calves were fed with colostrum having insufficient antibodies before first suckling. A total of 28 Holstein calves were fed assigned into control and treatment groups. The calves were fed fresh colostrum from their respective mother for the first 4 days. The treatment group calves were orally administered IgLock (10 g/d/calf) immediately before the first colostrum feeding and IgLock was administered just one time in treatment group calves. Then, the calves were offered normal milk until weaning. After weaning, all calves kept same paddock and were fed same ration. Diarrhea and respiratoric diseases were recorded for one year. Blood was collected from all calves in the study on birth day (0 day) before vaccination and IgLock administration, then, collected for the following 2 days in all groups. Albumin (ALB), Total Protein (TP), Aspartate Aminotransferase (AST), Alanine Aminotrasferase (ALT), Gamma-Glutamyl Transferase (GGT), Serum Amyloid A (SAA), Haptoglobin (HPT) and Ig G analyses were performed on all samples. Although serum ALB, ALT, GGT and Ig G levels were not shown a time dependent-change within control group; serum TP, AST, HPT and SAA levels were significantly changed by the time within mentioned group. Serum TP level was steady at first 2 days, then, it was increased significantly at 3rd day. Also, serum AST level was significantly increased at 2nd day, then it was descended to first day levels again at 3rd day. Although serum HPT levels were shown a significant gradually decreasing within control group, serum SAA levels were decreased rapidly after first day and there were no significance differences between 2nd and 3rd day in SAA levels. Serum ALB, ALT, HPT and SAA levels were not shown a time dependent-change within treatmet group. After first day Serum TP, GGT, AST and Ig G levels were shown an significant increasing at 2nd day. Serum TP, GGT and Ig G levels were higher as compared to 1st day within treatment group at 3rd day. But, serum AST level was less significantly 3rd day as compared to 2nd day values. The total numbers of calves suffered from diarrhea were significantly less in treatment group as compared to control group (p < 0,05). The pneumonia reappear ratio in calves suffered the diseases is 33,3% in control group and 11,11% in treatment group. Total cost of diseases and additives was 2339,36 $ for control and 1276,4 $ for treatment. As a conclusion, the immunity enhancers like IgLock are important and cost-effective to boost up immunity status in the early age which would be having positive effects on calves were received colostrum included insufficient antibodies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dairy%20calves" title="dairy calves">dairy calves</a>, <a href="https://publications.waset.org/abstracts/search?q=Ig%20Y" title=" Ig Y"> Ig Y</a>, <a href="https://publications.waset.org/abstracts/search?q=pneumonia" title=" pneumonia"> pneumonia</a>, <a href="https://publications.waset.org/abstracts/search?q=scours" title=" scours"> scours</a> </p> <a href="https://publications.waset.org/abstracts/27697/effects-of-ig-y-supplementation-to-colostrum-having-insufficient-antibodies-on-calves-metabolism-and-costs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27697.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">494</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Effect of Probiotic (RE3) Supplement on Growth Performance, Diarrhea Incidence and Blood Parameters of N'dama Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20Abdul%20Aziz">Y.

This study sought to investigate the effects of Probiotic (RE3) on growth performance, diarrhea incidence and blood parameters of N’dama calves. Sixteen N’dama calves aged 3 months of an average initial weight of 44.2 kg were randomly assigned to one of four dietary treatments according to their body weight, age, and sex. Treatment 1 (T1) serve as a control animal (No RE3 supplementation). Treatment 2 (T2) receives 0.03 ml RE3 per kg body weight. Treatment 3 (T3) receives 0.06 ml RE3 per kg body weight, and Treatment 4 (T4) also receives 0.09 ml RE3 per kg body weight in a Completely Randomize Design (CRD). There were 4 replicates per treatment. The calves were allowed access to feed and water ad libitum. The body weight of the calves was recorded at the start of the experiment and thereafter regularly at two weeks interval. Weighing was done early morning before the calves are allowed to access feed and water and were also observed in their pens for occurrence of diarrhea and faecal scores recorded. Blood samples were obtained from each calf at the end of the study through jugular vein puncture. Supplementation of RE3 to calves had showed a beneficial effect by reducing the incidence of diarrhea. The highest faecal score was recorded in T1 and the least faecal score was recorded in T3. There was significant difference (P < 0.05) in the faecal score between the treatment group and the control after two weeks of the experiment. There was no significant difference (P > 0.05) in the average daily gain of the animals. Hematological and biochemical indices of calves were all within the normal range except in treatments (1, 3 and 4) which recorded high White Blood Cell (WBC) count with no significant difference (P > 0.05). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=probiotics%20%28RE3%29" title="probiotics (RE3)">probiotics (RE3)</a>, <a href="https://publications.waset.org/abstracts/search?q=diarrhea%20incidence" title=" diarrhea incidence"> diarrhea incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20parameters" title=" blood parameters"> blood parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=N%E2%80%99dama%20calves" title=" N’dama calves"> N’dama calves</a> </p> <a href="https://publications.waset.org/abstracts/91757/effect-of-probiotic-re3-supplement-on-growth-performance-diarrhea-incidence-and-blood-parameters-of-ndama-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91757.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Effects of a Bacteria-Based Probiotic on Subpopulations of Peripheral Leukocytes and Their Interleukin mRNA Expression in Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Qadir%20Qadis">Abdul Qadir Qadis</a>, <a href="https://publications.waset.org/abstracts/search?q=Satoru%20Goya"> Satoru Goya</a>, <a href="https://publications.waset.org/abstracts/search?q=Minoru%20Yatsu"> Minoru Yatsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-uki%20Yoshida"> Yu-uki Yoshida</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshihiro%20Ichijo"> Toshihiro Ichijo</a>, <a href="https://publications.waset.org/abstracts/search?q=Shigeru%20Sato"> Shigeru Sato</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bacterial probiotics are known to modulate the gut-associated lymphoid and epithelial tissue response to enhance the activities of intestinal and systemic immune system in human and animals. In cattle, the immune-stimulatory effects of probiotics have been evaluated during intestinal disorders. To investigate the effects of probiotic on the function of peripheral blood mononuclear cells, eight healthy Holstein calves (10 ± 3 weeks) were assigned to a 4 × 2 experimental design. The probiotic, consisting of Lactobacillus plantarum, Enterococcus faecium and Clostridium butyricum, was administered orally at 3.0 g/100 kg body weight to calves once daily for 5 consecutive days. Calves given no probiotic served as the control. In the treatment group, increases in numbers of CD282+ monocytes, CD3+ T-cells and CD4+, CD8+ and WC1+ γδ T- cell subsets were noted on day 7 post-placement compared to pre-dose day and the control group. Expression of interleukin-6, interferon-gamma and tumor necrosis factor-alpha was elevated in peripheral leukocytes on days 7 and 14. These results suggest that peripheral blood leukocytes in healthy calves may be stimulated via the gastrointestinal microbiota, which was increased by the oral probiotic treatment. The 5-day repeated administration of a bacterial probiotic may enhance cellular immune function in weaned calves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacterial-probiotic" title="bacterial-probiotic">bacterial-probiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=calf" title=" calf"> calf</a>, <a href="https://publications.waset.org/abstracts/search?q=interleukin" title=" interleukin"> interleukin</a>, <a href="https://publications.waset.org/abstracts/search?q=leukocyte" title=" leukocyte"> leukocyte</a> </p> <a href="https://publications.waset.org/abstracts/6561/effects-of-a-bacteria-based-probiotic-on-subpopulations-of-peripheral-leukocytes-and-their-interleukin-mrna-expression-in-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6561.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">660</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> The Pathology of Bovine Rotavirus Infection in Calves That Confirmed by Enzyme Linked Immunosorbant Assay, Reverse Transcription Polymerase Chain Reaction and Real-Time RT-PCR</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shama%20Ranjan%20Barua">Shama Ranjan Barua</a>, <a href="https://publications.waset.org/abstracts/search?q=Tofazzal%20M.%20Rakib"> Tofazzal M.

The present study was carried out to investigate the pathology of neonatal enteritis in calves due to bovine rotavirus infection in south-eastern part of Bangladesh. Rotavirus was identified by using ELISA, RT-PCR (Reverse Transcription Polymerase Chain Reaction), real-time RT-PCR. We examined 12 dead calves with history of diarrhea during necropsy. Among 12 dead calves, in gross examination, 6 were found with pathological changes in intestine, 5 calves had congestion of small intestine and rest one had no distinct pathological changes. Intestinal contents and/or faecal samples of all dead calves were collected and examined to confirm the presence of bovine rotavirus A using Enzyme linked immunosorbant assay (ELISA), RT-PCR and real-time RT-PCR. Out 12 samples, 5 (42%) samples revealed presence of bovine rotavirus A in three diagnostic tests. The histopathological changes were found almost exclusively limited in the small intestine. The lesions of rotaviral enteritis ranged from slight to moderate shortening (atrophy) of villi in the jejunum and ileum with necrotic crypts. The villi were blunt and covered by immature epithelial cells. Infected cells, stained with Haematoxylin and Eosin staining method, showed characteristic syncytia and eosinophilc intracytoplasmic inclusion body. The presence of intracytoplasmic inclusion bodies in enterocytes is the indication of viral etiology. The presence of rotavirus in the affected tissues and/or lesions was confirmed by three different immunological and molecular tests. The findings of histopathological changes will be helpful in future diagnosis of rotaviral infection in dead calves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calves" title="calves">calves</a>, <a href="https://publications.waset.org/abstracts/search?q=diarrhea" title=" diarrhea"> diarrhea</a>, <a href="https://publications.waset.org/abstracts/search?q=pathology" title=" pathology"> pathology</a>, <a href="https://publications.waset.org/abstracts/search?q=rotavirus" title=" rotavirus"> rotavirus</a> </p> <a href="https://publications.waset.org/abstracts/77041/the-pathology-of-bovine-rotavirus-infection-in-calves-that-confirmed-by-enzyme-linked-immunosorbant-assay-reverse-transcription-polymerase-chain-reaction-and-real-time-rt-pcr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77041.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">252</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Incidence and Etiology of Neonatal Calf Diarrhea in the Region of Blida, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Dadda">A.

The experiment was carried out at District AI Station. Four pluriparous cows and four nulliparous heifers were used in this study and they were housed in free stall barns. The heifers fed with corn silage supplemented with UMMB, while the cows fed with green fodder. All animals were given 500 mg cloprostenolum i.m. injections PGF2α twice, 11 days apart, to synchronize the occurrence of estrus. Estrus was detected by visual observation twice a day and determined if all cattle accepted mount from other females. All animals were inseminated twice with Bali sexed-semen at 72 and 76 h after observed oestrus. Results suggested that the percentage of calving rate either for pluriparous cows or nulliparous heifers were recorded to be 75 percent. One cow and one heifer did not produce calves because of embryonic lost. Regardless the sex of calves, the mean of birth weight of calves in cows was higher than that of heifers (18.50 ± 2.60 kg vs 13.83 ± 5.20 kg). One female calf from heifer with lower birth weight (8.0 kg) was dead one day after born. In pluriparous group, two cows delivered male calves and the other delivered female calf. Conversely in nulliparous group, two heifers delivered female calves and the other male calf. It is concluded that under the conditions of this preliminary trials, the sex ratio between pluriparous and nulliparous groups was found to be 50:50 (male:female). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20insemination" title="artificial insemination">artificial insemination</a>, <a href="https://publications.waset.org/abstracts/search?q=bali%20cattle" title=" bali cattle"> bali cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=calves" title=" calves"> calves</a>, <a href="https://publications.waset.org/abstracts/search?q=sexed%20sperm" title=" sexed sperm"> sexed sperm</a> </p> <a href="https://publications.waset.org/abstracts/40944/artificial-insemination-of-bali-cattle-with-frozen-thawed-sexed-sperm-under-district-ai-station-conditions-in-lombok-a-preliminary-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40944.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">311</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Effect of Food Supplies Holstein Calves Supplemented with Bacillus Subtilis PB6 in Morbidity and Mortality </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Banca%20Patricia%20Pena%20Revuelta">Banca Patricia Pena Revuelta</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramiro%20Gonzalez%20Avalos"> Ramiro Gonzalez Avalos</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Leonardo%20Rocha%20Valdez"> Juan Leonardo Rocha Valdez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20%20Gonzalez%20Avalos"> Jose Gonzalez Avalos</a>, <a href="https://publications.waset.org/abstracts/search?q=Karla%20Rodriguez%20Hernandez"> Karla Rodriguez Hernandez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Probiotics are a promising alternative to improve productivity and animals' health. In addition, they can be part of the composition of different types of products, including foods (functional foods), medicines, and dietary supplements. The objective of the present work was to evaluate the effect of the feeding of Holstein calves supplemented with bacillus subtilis PB6 in morbidity and mortality. 60 newborn animals were used, randomly included in 1 of 3 treatments. The treatments were as follows: T1 = control, T2 = 10 g / calf / day. The first takes within 20 min after birth, T3 = 10 g / calf/day. The first takes between 12 and 24 h after birth. In all the treatments, 432 L of pasteurized whole milk divided into two doses/day 07:00 and 15:00, respectively, were given for 60 days. The addition of bacillus subtilis PB6 was carried out in the milk tub at the time of feeding them. The first colostrum intake (2 L • intake) was given within 2 h after birth, after which they were given a second 6 h after the first one. The diseases registered to monitor the morbidity and mortality of the calves were: diarrhea and pneumonia. The registry was carried out from birth to 60 days of life. The parameter evaluated was food consumption. The variable statistical analysis was performed using analysis of variance, and comparison of means was performed using the Tukey test. The value of P < 0.05 was used to consider the statistical difference. The results of the present study in relation to the consumption of food show no statistical difference P < 0.05 between treatments (14,762, 11,698, and 12,403 kg of food average, respectively). Calves group to which they were not provided Bacillus subtilis PB6 obtained higher feed intake. The addition of Bacillus subtilis PB6 in feeding calves does not increase feed intake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=feeding" title="feeding">feeding</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=milk" title=" milk"> milk</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotic" title=" probiotic "> probiotic </a> </p> <a href="https://publications.waset.org/abstracts/118983/effect-of-food-supplies-holstein-calves-supplemented-with-bacillus-subtilis-pb6-in-morbidity-and-mortality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118983.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Identification and Molecular Characterization of Cryptosporidium Spp. in Pre-Wean Dairy Calves in Mashhad, Northeastern of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Asadpour">Mohammad Asadpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Razmi"> Gholamreza Razmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Mohammadi"> Gholamreza Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abolghasem%20Naghibi"> Abolghasem Naghibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cryptosporidium Spp., protozoan parasites of the phylum Apicomplexa, have a wide spectrum of hosts including humans, domestic animals and wild mammals, birds, reptiles, amphibians and fish. Dairy cattle have been identified in numerous reports as a major source of environmental contamination with this pathogen. In this study, a Polymerase Chain Reaction (PCR), Restriction Fragment Length Polymorphism (RFLP) analysis of the Small-Subunit (SSU) rRNA gene was used to detect and identify Cryptosporidium Spp. in 300 fecal specimens from 1 to 30 days pre-wean calves in 10 farms in Mashhad, Iran. Eighty five (28.3%) and forty five (15%) of the specimens were positive for Cryptosporidium by microscopic and PCR examination respectively. Restriction digestion of the PCR products by VSPI and Ssp1 restriction enzymes and analysis of sequence data revealed the presence of C. parvum, bovine genotype in all isolates. Our findings suggest that cattle can be a source of Cryptosporidial infections for humans and animals in Mashhad area. This is the first published description of Cryptosporidium sub genotyping in Mashhad. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptosporidium" title="cryptosporidium">cryptosporidium</a>, <a href="https://publications.waset.org/abstracts/search?q=genotype" title=" genotype"> genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy%20calves" title=" dairy calves"> dairy calves</a>, <a href="https://publications.waset.org/abstracts/search?q=18S%20rRNA" title=" 18S rRNA"> 18S rRNA</a>, <a href="https://publications.waset.org/abstracts/search?q=Mashhad" title=" Mashhad"> Mashhad</a> </p> <a href="https://publications.waset.org/abstracts/5569/identification-and-molecular-characterization-of-cryptosporidium-spp-in-pre-wean-dairy-calves-in-mashhad-northeastern-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5569.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">413</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Rumen Epithelium Development of Bovine Fetuses and Newborn Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juliana%20Shimara%20Pires%20Ferr%C3%A3o">Juliana Shimara Pires Ferrão</a>, <a href="https://publications.waset.org/abstracts/search?q=Let%C3%ADcia%20Palmeira%20Pinto"> Letícia Palmeira Pinto</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Palma%20Renn%C3%B3"> Francisco Palma Rennó</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Javier%20Hernandez%20Blazquez"> Francisco Javier Hernandez Blazquez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ruminant stomach is a complex and multi-chambered organ. Although the true stomach (abomasum) is fully differentiated and functional at birth, the same does not occur with the rumen chamber. At this moment, rumen papillae are small or nonexistent. The papillae only fully develop after weaning and during calf growth. Papillae development and ruminal epithelium specialization during the fetus growth and at birth must be two interdependent processes that will prepare the rumen to adapt to ruminant adult feeding. The microscopic study of rumen epithelium at these early phases of life is important to understand how this structure prepares the rumen to deal with the following weaning processes and its functional activation. Samples of ruminal mucosa of bovine fetuses (110- and 150 day-old) and newborn calves were collected (dorsal and ventral portions) and processed for light and electron microscopy and immunohistochemistry. The basal cell layer of the stratified pavimentous epithelium present in different ruminal portions of the fetuses was thicker than the same portions of newborn calves. The superficial and intermediate epithelial layers of 150 day-old fetuses were thicker than those found in the other 2 studied ages. At this age (150 days), dermal papillae begin to invade the intermediate epithelial layer which gradually disappears in newborn calves. At birth, the ruminal papillae project from the epithelial surface, probably by regression of the epithelial cells (transitory cells) surrounding the dermal papillae. The PCNA cell proliferation index (%) was calculated for all epithelial samples. Fetuses 150 day-old showed increased cell proliferation in basal cell layer (Dorsal Portion: 84.2%; Ventral Portion: 89.8%) compared to other ages studied. Newborn calves showed an intermediate index (Dorsal Portion: 65.1%; Ventral Portion: 48.9%), whereas 110 day-old fetuses had the lowest proliferation index (Dorsal Portion: 57.2%; Ventral Portion: 20.6%). Regarding the transitory epithelium, 110 day-old fetuses showed the lowest proliferation index (Dorsal Portion: 44.6%; Ventral Portion: 20.1%), 150 day-old fetuses showed an intermediate proliferation index (Dorsal Portion: 57.5%; Ventral Portion: 71.1%) and newborn calves presented a higher proliferation index (Dorsal Portion: 75.1%; Ventral Portion: 19.6%). Under TEM, the 110- and 150 day-old fetuses presented thicker and poorly organized basal cell layer, with large nuclei and dense cytoplasm. In newborn calves, the basal cell layer was more organized and with fewer layers, but typically similar in both regions of the rumen. For the transitory epithelium, fetuses displayed larger cells than those found in newborn calves with less electrondense cytoplasm than that found in the basal cells. The ruminal dorsal portion has an overall higher cell proliferation rate than the ventral portion. Thus we can infer that the dorsal portion may have a higher cell activity than the ventral portion during ruminal development. Moreover, the basal cell layer is thicker in the 110- and 150 day-old fetuses than in the newborn calves. The transitory epithelium, which is much reduced, at birth may have a structural support function of the developing dermal papillae. When it regresses or is sheared off, the papillae are “carved out” from the surrounding epithelial layer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bovine" title="bovine">bovine</a>, <a href="https://publications.waset.org/abstracts/search?q=calf" title=" calf"> calf</a>, <a href="https://publications.waset.org/abstracts/search?q=epithelium" title=" epithelium"> epithelium</a>, <a href="https://publications.waset.org/abstracts/search?q=fetus" title=" fetus"> fetus</a>, <a href="https://publications.waset.org/abstracts/search?q=hematoxylin-eosin" title=" hematoxylin-eosin"> hematoxylin-eosin</a>, <a href="https://publications.waset.org/abstracts/search?q=immunohistochemistry" title=" immunohistochemistry"> immunohistochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=TEM" title=" TEM"> TEM</a>, <a href="https://publications.waset.org/abstracts/search?q=Rumen" title=" Rumen"> Rumen</a> </p> <a href="https://publications.waset.org/abstracts/51372/rumen-epithelium-development-of-bovine-fetuses-and-newborn-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51372.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">388</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Effect of Different SE Diets on Blood SE, TAC Levels in Dairy Cattle and Their Newborn Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moshfeghi%20Sogand">Moshfeghi Sogand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Free radicals can be produced during the respiratory oxidation of different cells. These free radicals can damage to various macromolecules as protein ,fat, nucleic acids and … are harmful for body. The natural defence system that can prevent the damage of free radicals and nuteralized them , have tittled under the name total antioxidant capacity (TAC ). Se is one main antioxidant part in TAC , because it is one main part in structure of some body antioxidant enzymes such as GPX(glutathione peroxidase). Blood SE ,GPX and TAC probably can change by feeding of different selenium supplement diet in late pregnancy and also may transport from maternal blood to its fetus or by clostrum after calving. In this respect we have determined 100 pregnant dairy cattle (in the same condition of age , race and number of parturient) then devided them to 4 groups feed them in 3 last pregnancy months by different selenium diets. Group1:controle no se supplementation , group2: recived 0/3 ppm of the daily diet Saccharomyces Cervisiae . group3 :recived selenium _ rich yeast(containing200ppm selenium)was mixed with total daily ration fed. Group4: recived se _rich yeast(containing300 ppm selenium)was mixed with total daily ration fed. Then measured blood SE,GPX and TAC levels in them and in 3 days newborn calves after calving. The results were analysed by Tukey Anova test and the highest level of blood SE ,GPX and TAC was shown in cattle that feed fermented SE_yeast diet and in their 3 days newborn calves. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SE" title="SE">SE</a>, <a href="https://publications.waset.org/abstracts/search?q=TAC" title=" TAC"> TAC</a>, <a href="https://publications.waset.org/abstracts/search?q=SE%20DIETS" title=" SE DIETS"> SE DIETS</a>, <a href="https://publications.waset.org/abstracts/search?q=FRAP" title=" FRAP"> FRAP</a> </p> <a href="https://publications.waset.org/abstracts/186629/effect-of-different-se-diets-on-blood-se-tac-levels-in-dairy-cattle-and-their-newborn-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186629.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">44</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Adrenergic and Non-Adrenergic Control of Mesenteric Blood Vessels of Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Elmajdoub">A.

El-Mahmoudy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was designed to investigate the neurotransmitters that mediate the excitatory response of the circular muscle of final branches of mesenteric artery in bovine calves. Mesentery was dissected and the iliac branches were separated and used. The final mesenteric branches of diameter 400 micrometers and less responded strongly to norepinephrine and moderately to ATP. However, the mesenteric branches of wider diameters were gradually less responsive to norepinephrine and those of diameter 700 micrometers were exclusively nonresponsive. These arteries were strongly responsive to ATP (100 µM). Norepinephrine response was sensitive to phentolamine (3 µM) and prazosin (5 µM) indicating that it is mediated by α1 receptor; while ATP response was sensitive to suramin (200 µM), PPADS (50 µM), but not to cibacron blue (100 µM) indicating that it is mediated via P2X receptor. Further confirmatory experiments were performed including application of α1 and P2X receptor specific agonists which are methoxamine and α,β-methylene ATP. Methoxamine (1 µM) showed effects similar to norepinephrine in final branches and was without effect in wider branches. α,β-methylene ATP (1 µM), exhibited more pronounced effects on both wide and narrow branches but in parallel manner to that of ATP. Agonists for α2 and P2Y receptors as clonidine (10 µM) and 2-meThio ATP (10 µM), respectively, were without effect indicating that involvement of these receptors is unlikely. The neuropeptide-Y (200 nM) did not have any effects on either the narrow or the wide rings. Conclusion: These data may imply that in the most peripheral mesenteric arteries a strong vasopressor power represented by norepinephrine and ATP integration is needed for maintaining peripheral resistance; on the other hand a mild vasopressor power mediated only by ATP is enough to maintain the vascular tone in the relatively central mesenteric branches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ATP" title="ATP">ATP</a>, <a href="https://publications.waset.org/abstracts/search?q=calves" title=" calves"> calves</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenteric%20artery" title=" mesenteric artery"> mesenteric artery</a>, <a href="https://publications.waset.org/abstracts/search?q=norepinephrine" title=" norepinephrine"> norepinephrine</a> </p> <a href="https://publications.waset.org/abstracts/3157/adrenergic-and-non-adrenergic-control-of-mesenteric-blood-vessels-of-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3157.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">305</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Effect of Varying Levels of Concentrate Ration on the Performance of Nili-Ravi Buffalo Heifer Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Z.%20M.%20Iqbal">Z.

Twenty seven buffalo heifers were randomly divided into three different groups A, B and C having nine animals in each group. All the heifers were given free access to chopped green fodder and fresh water. In addition, heifers of group A, B and C were given concentrate at the rate of 0.5%, 1% and 1.5% of their body weight. The average daily dry matter intake was 2.69, 3.06 and 3.83 kg with average daily gain of 456.09, 398.56 and 515.87 gm in group A, B and C, respectively. The feed conversion ratio of heifers of these groups was 5.89, 7.74 and 7.52, respectively. There was non-significant (P>0.05) difference in the body measurements (height at wither, body length and heart girth), final body condition and scoring and blood serum (glucose, total protein and cholesterol) of heifers of all the three groups. The results of current study shows that there is non-significant (P>0.05) difference in the growth rate of Nili-Ravi heifers at varying levels of concentrate so, it is cost effective to raise 6-8 month calves by offering concentrate at the rate of 0.5% body weight along with free access of green fodder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concentrate%20level" title="concentrate level">concentrate level</a>, <a href="https://publications.waset.org/abstracts/search?q=buffalo%20heifer" title=" buffalo heifer"> buffalo heifer</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20measurement" title=" body measurement"> body measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20fodder" title=" green fodder "> green fodder </a> </p> <a href="https://publications.waset.org/abstracts/5540/effect-of-varying-levels-of-concentrate-ration-on-the-performance-of-nili-ravi-buffalo-heifer-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5540.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">422</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Biometry and Pathology of Internal Genital Organs of Female Camel (Camelus dromedarius) in Lahore, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umair%20Riaz">Umair Riaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mudassar%20Iqbal"> Mudassar Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Umer%20Farooq"> Umer Farooq</a>, <a href="https://publications.waset.org/abstracts/search?q=Farah%20Ali"> Farah Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Musadiq%20Idris"> Musadiq Idris</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work was designed to establish biometrical norms for ovaries, oviducts and crevices of one humped camels (Camelus dromedarius) and the diseases associated thereof in various age groups viz. calves (< 2 years, n=15), heifers (2-4 years, n=34) and adults (> 4 years, n=81). The genitalia were attained from Lahore Abbatoir, Punjab, Pakistan. Ovaries, oviducts and cervices of experimental genitalia were assessed for their length, width, thickness and weight. Statistically, there was no difference in the length and width of both left and right ovaries which however, increased with the advancement of age of camel. Similar results were noticed regarding the width of oviducts. The mean length of cervices of female camels correlated well with the number of cervical annular rings amongst the age groups. Regarding the abnormalities of ovaries and cervices in the 3 age groups, camel calves did not have any of the abnormalities. However, ovarian hypoplasia in heifers (2.94%) and follicular cyst in adult female camels (1.23%) were revealed in the present study. Mucocervix in heifers (2.96%) and cervicitis 1.23% in adult camels was also noticed.

In Pakistan, its prevalence is up to 29% in the cattle and buffalo population in different regions. Cattle show a long lasting and durable immunity by giving an infection of B.bovis, B. bigemina, or Babesiadivergens. this is used in cattle to immunize them in a few countries as anti-babesiosis vaccine. Development of frozen vaccine allows for complete testing after production of each batch, However, once thawed, its reduced its shelf life, frozen vaccines are more difficult to transport as well as expensive to produce as compared to chilled vaccine. The contamination of blood derived vaccine has the potential risk that makes pre-production and post-production quality control necessary. For the trail master seed production of whole blood frozen bivalent Babesia(Babesiabovis and Babesiabigemina), 100 blood samples of Babesial positive suspected cattle was taken and processed for separation microscopic detection and rectification by PCR. Vaccine passages were done to reduce the parasitaemiasis in live calves. After 8 passages, parasitemia of Babesia reduced from 80% to 15%. Infected donor calf’s blood was taken by jugular cannulation by using preservative free lithium heparin as an anticoagulant (5 International Units IU heparin/ml blood). In lab, parasite containing blood was mixed in equal volumes with 3 M glycerol in PBS supplemented with 5 mM glucose (final concentration of glycerol 1.5 M) at 37°C. The mixture was then equilibrized at 37°C for 30 minutes and were dispensed in required containers (e.g., 5 ml cryovials). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distribution" title="distribution">distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=babesia" title=" babesia"> babesia</a>, <a href="https://publications.waset.org/abstracts/search?q=primer%20sequences" title=" primer sequences"> primer sequences</a>, <a href="https://publications.waset.org/abstracts/search?q=PCV" title=" PCV"> PCV</a> </p> <a href="https://publications.waset.org/abstracts/152432/preparation-of-frozen-bivalent-babesial-babesia-bovis-and-babesia-bigemina-vaccine-from-field-isolates-and-evaluation-of-its-efficacy-in-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152432.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">104</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Performance of Growing Rahaji Bulls Fed Diets Containing Similar Concentrates and Different Crop Residues in a Semi-Arid Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Husaini%20Sama">Husaini Sama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study was conducted, in a 120 - day’s trial, to monitor the performance of growing Rahaji bulls fed different crop residues. There were four experimental treatments, each containing three (3) bull-calves. The first three (experimental) diets were prepared with rice straw, millet stalks and a combination of the two in equal proportions. These 3 diets were supplemented with concentrates. Treatments 1, 2 and 3 consisted of rice straw, millet stalk and combination of rice straw and millet stalk in equal ratio, respectively as basal feeds, while, Treatment 4 (containing standard diet of cow pea haulms, rice straw and wheat offal) served as control to compare with the other treatments. Data on feed intake and livability was collected on daily basis and that of live weight gain and feed conversion ratio were collected fortnightly, but data on apparent nutrient retention trial was collected towards the end of the experiment. Water was offered ad libitum. Records obtained were subjected to statistical analysis using SPSS (1988) software package in accordance with a Completely Randomized Design (CRD). Results obtained indicated that feed intake was significantly higher (P<0.05) for calves on treatments 3 and 4 compared to those on treatments 1and 2. The study observed that it was cheaper to formulate diets 2 and 3 than the other 2 diets. The control diet (T4) was observed to be relatively more expensive than the other 3 formulated diets. It was concluded from the findings that, concentrate containing combination of rice straw and cereal stalks was economical and satisfactory for feeding growing Rahaji bulls in this ecological zone
