Conjunctival and cloacal swabs from 54 captive psittacine birds presented at veterinary clinics were collected to determine the prevalence of C. psittaci in domestic birds in Isfahan. Samples were collected during 2014 from a total of 10 different species of parrots, with African gray(33), Cockatiel lutino(3), Cockatiel gray(2), Cockatiel cinnamon(1), Pearl cockatiel(6), Timneh African grey(1), Ringneck parakeet(2), Melopsittacus undulatus(1), Alexander parakeet(2), Green Parakeet(3) being the most representative species sampled. C. psittaci was detected in 27 (50%) birds using molecular detection (PCR) method. The detection of this bacterium in captive psittacine birds shows that there is a potential risk for human whom has a direct contact and there is a possibility of infecting other birds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chlamydophila%20psittaci" title="chlamydophila psittaci">chlamydophila psittaci</a>, <a href="https://publications.waset.org/abstracts/search?q=psittacine%20birds" title=" psittacine birds"> psittacine birds</a>, <a href="https://publications.waset.org/abstracts/search?q=PCR" title=" PCR"> PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=Isfahan" title=" Isfahan"> Isfahan</a> </p> <a href="https://publications.waset.org/abstracts/39281/detection-and-identification-of-chlamydophila-psittaci-in-asymptomatic-and-symptomatic-parrots-in-isfahan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39281.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">371</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">276</span> Bird Diversity along Boat Touring Routes in Tha Ka Sub-District, Amphawa District, Samut Songkram Province, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Charoenpokaraj">N.

The data was analyzed to find the abundance, and similarity index of the birds. The results from the survey of birds on all three routes found that there are 33 families and 63 species. Route 3 (traditional coconut sugar making kiln – resort) had the most species; 56 species. There were 18 species of commonly found birds with an abundance level of 5, which calculates to 28.57% of all bird species. In August, 46 species are found, being the greatest number of bird species benefiting from this route. As for the status of the birds, there are 51 resident birds, 7 resident and migratory birds, and 5 migratory birds. On Route 2 and Route 3, the similarity index value is equal to 0.881. The birds are classified by their activity characteristics i.e. insectivore, piscivore, granivore, nectrivore and aquatic invertebrate feeder birds. Some birds also use the area for nesting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bird%20diversity" title="bird diversity">bird diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=boat%20touring%20routes" title=" boat touring routes"> boat touring routes</a>, <a href="https://publications.waset.org/abstracts/search?q=Samut%20Songkram" title=" Samut Songkram"> Samut Songkram</a>, <a href="https://publications.waset.org/abstracts/search?q=similarity%20index" title=" similarity index"> similarity index</a> </p> <a href="https://publications.waset.org/abstracts/10542/bird-diversity-along-boat-touring-routes-in-tha-ka-sub-district-amphawa-district-samut-songkram-province-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10542.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">334</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">275</span> Sensory Evaluation of Meat from Broilers Bird Fed Detoxified Jatropher Curcas and that Fed Conventional Feed</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20S.%20Lawal">W.

Two hundred and forty (240) day-old commercial broiler chicks were randomly allotted to four dietary treatments having four replicates each. Each replicate had 15 birds. The levels of inclusion were 0g (Control group), 4g, 8g and 12g/Kg feed. The experiment lasted for eight weeks. The results of the study revealed that the initial body weight was significantly (P < 0.05) higher in birds fed 12g/kg diet than those fed 0, 4, and 8g MOLP. The birds fed 0, 4 and 8g/kg diet however had similar weights. The final body weight was significantly (P < 0.05) higher in the birds fed 12g MOLP than those fed 0, 4 and 8g MOLP. The final weights were similar in the birds fed 4 and 8g/kg diet but higher (P < 0.05) than those of the birds in the control group. The body weight gain was similar in birds fed 0 and 4g MOLP but significantly higher (P < 0.05) than those of the birds in 12g/kg diet. There were no significant differences (P > 0.05) in the feed intake. The serum albumin of the birds fed 12g MOLP/Kg diet (48.85g/L) was significantly (P < 0.05) higher than the mean value of those fed the control diet 0 and 8g MOLP/Kg diets having 36.05 and 37.10g/L respectively. Birds fed 12g MOLP/Kg feed recorded the lowest level of triglyceride (122.75g/L) which was significantly (P < 0.05) lower than those of the birds fed 0 and 4g/kg diet MOLP. The serum corticosterone decreased with increase in MOLP inclusion levels. The birds fed 12g MOLP had the least value. This study has shown that MOLP may contain potent antioxidants capable of ameliorating the effects of heat stress in broiler chickens with 12g MOLP inclusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=physiology" title="physiology">physiology</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20stress" title=" heat stress"> heat stress</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-oxidant" title=" anti-oxidant"> anti-oxidant</a> </p> <a href="https://publications.waset.org/abstracts/26533/effect-of-inclusion-of-moringa-oleifera-leaf-on-physiological-responses-of-broiler-chickens-at-finisher-phase-during-hot-dry-season" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26533.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">351</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">273</span> Egg Yolk and Serum Cholesterol Reducing Effect of Garlic and Natural Cocoa Powder Using Laying Birds as Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onyimonyi%20Anselm%20Ego">Onyimonyi Anselm Ego</a>, <a href="https://publications.waset.org/abstracts/search?q=Obi-Keguna%20Christy"> Obi-Keguna Christy</a>, <a href="https://publications.waset.org/abstracts/search?q=Dim%20Emmanuel%20Chinonso"> Dim Emmanuel Chinonso</a>, <a href="https://publications.waset.org/abstracts/search?q=Ugwuanyi%20Evelyn"> Ugwuanyi Evelyn</a>, <a href="https://publications.waset.org/abstracts/search?q=Uzochukwu%20Ifeanyi%20Emmanuel"> Uzochukwu Ifeanyi Emmanuel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A total of 144 Shaver Brown Layers in their sixteenth week of lay were used in a twelve weeks study to evaluate the egg yolk and serum cholesterol of the birds when fed varying dietary combinations of garlic and natural cocoa powder. The birds were randomly assigned into nine dietary treatments with 16 birds per treatment. Each bird was housed separately in a cage measuring 45 cm x 35 cm in an open sided battery cage house typical of the tropics. A standard poultry mash diet with 16.5% CP and 2800 KcalME/kg was formulated as the basal ration which also served as the control diet. Garlic and natural cocoa powder were incorporated in varying combinations (50 g or 100 g/100 kg of feed) in the remaining eight treatments. Weekly data of egg weight, egg length, egg diameter, yolk weight, albumen weight and hen day egg production were kept. Egg yolk and serum cholesterol levels were determined using a Randox kit. Results showed that birds receiving garlic and natural cocoa powder had significantly (P<0.05) reduced egg and albumen weight as compared to control birds. Hen day production of the birds was also significantly higher than control birds. Egg yolk and serum cholesterol of birds receiving the garlic and natural cocoa powder were significantly (P<0.05) lower than the control. Serum cholesterol levels showed decline in the birds receiving garlic and natural cocoa powder. The least yolk cholesterol level of 160 mg/dl was observed in birds receiving 50g garlic and 50 g natural cocoa powder (Treatment 5). Control birds had an egg cholesterol level of 245.45 mg/dl. It was concluded that incorporating garlic and natural cocoa powder in the diets of laying hens can result in a significant reduction in the egg and serum cholesterol levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=egg" title="egg">egg</a>, <a href="https://publications.waset.org/abstracts/search?q=serum" title=" serum"> serum</a>, <a href="https://publications.waset.org/abstracts/search?q=cholesterol" title=" cholesterol"> cholesterol</a>, <a href="https://publications.waset.org/abstracts/search?q=garlic" title=" garlic"> garlic</a> </p> <a href="https://publications.waset.org/abstracts/30162/egg-yolk-and-serum-cholesterol-reducing-effect-of-garlic-and-natural-cocoa-powder-using-laying-birds-as-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30162.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">766</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">272</span> Prevalence of Cryptosporidium spp. in Free-Living Wild Birds by Using Carbol Fuchsin Staining Methods in Konya, Turkey</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> </p> <p class="card-text"><strong>Abstract:</strong></p> Cryptosporidiosis is one of the most common parasitic infection in domesticated, caged, wild birds. Cryptosporidium sp. has been reported in over 30 avian species worldwide. Cryptosporidium meleagridis, Cryptosporidium baileyi and Cryptosporidium galli are recognised avian species of Cryptosporidium. This study was carried out to determine the prevalance of Cryptosporidium sp. in wild birds in Konya province, Turkey. Faecal samples were collected from 65 wild birds including 52 Podicipedidae (Podiceps cristatus), 11 Rallidae (Fulicia Atra), 2 Anitadia (Aytha ferina). Faecal samples were stained with Modified Ziehl-Neelsen staining technigue, they were examined under light microscope for the presence of Cryptosporidium sp. oocyts. Among the 65 faecal samples, 11 (16.9%) were found to be infected with Cryptosporidium sp. oocysts. The results of this study indicate that wild birds may play an important role in the epidemiology of Cryptosporidium. In conclusion, Cryptosporidiosis has suggested zoonotic potential and thus warrant further attention. In addition, biological and genetic studies are required to provide more information on Cryptosporidiosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cryptosporidium%20sp" title="Cryptosporidium sp">Cryptosporidium sp</a>, <a href="https://publications.waset.org/abstracts/search?q=wild%20birds" title=" wild birds"> wild birds</a>, <a href="https://publications.waset.org/abstracts/search?q=Konya" title=" Konya"> Konya</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkey" title=" Turkey"> Turkey</a> </p> <a href="https://publications.waset.org/abstracts/50934/prevalence-of-cryptosporidium-spp-in-free-living-wild-birds-by-using-carbol-fuchsin-staining-methods-in-konya-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50934.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">358</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">271</span> Curve Fitting by Cubic Bezier Curves Using Migrating Birds Optimization Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mitat%20Uysal">Mitat Uysal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new met heuristic optimization algorithm called as Migrating Birds Optimization is used for curve fitting by rational cubic Bezier Curves.

Data were kept on daily egg production, egg weight and feed intake. 10 eggs were collected per treatment at the end of the study for yolk cholesterol determination. Blood samples from four birds per treatment were collected and used for the serum cholesterol and triglycerides determination. Results showed that bird on treatment 3 (5% moringa leaf meal/kg of feed) had significantly higher (P < 0.05) Hen Day Egg Production record of 83.3% as against 78.75%, 65.05% and 66.67% recorded for the control, T2 and T4 birds, respectively. Egg weight of 56.39 g recorded for the same birds on treatment 3 was significantly (P< 0.05) lower than the values of 62.61 g, 60.99 g and 59.33 g recorded for birds on T4, T1 and T2, respectively. Yolk and serum cholesterol profiles of the moringa leaf meal fed birds were significantly (P<0.05) lowered when compared to those of the other treatments. Comparatively, the birds on the MOGA diets had significantly reduced yolk and serum cholesterol than the control. It is concluded that supplementation of moringa leaf meal and sun dried garlic powder at the levels used in this study will result in the production of nutritionally healthier eggs with less yolk and serum cholesterol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performance" title="performance">performance</a>, <a href="https://publications.waset.org/abstracts/search?q=cholesterol" title=" cholesterol"> cholesterol</a>, <a href="https://publications.waset.org/abstracts/search?q=moringa" title=" moringa"> moringa</a>, <a href="https://publications.waset.org/abstracts/search?q=garlic" title=" garlic"> garlic</a> </p> <a href="https://publications.waset.org/abstracts/5021/performance-yolk-and-serum-cholesterol-of-shaver-brown-layers-fed-moringa-leaf-meal-and-sun-dried-garlic-powder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5021.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">520</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">269</span> Growth Performance,haematological And Serum Biochemistry Of Broilers Fed Graded Levels Of Cocoyam (Xanthosoma Sagittifolium)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Urom%20Scholastica%20Mgbo">Urom Scholastica Mgbo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ifeanyichukwu"> Ifeanyichukwu</a>, <a href="https://publications.waset.org/abstracts/search?q=Vivian"> Vivian</a>, <a href="https://publications.waset.org/abstracts/search?q=Anaba"> Anaba</a>, <a href="https://publications.waset.org/abstracts/search?q=Uchemadu%20Martins"> Uchemadu Martins</a>, <a href="https://publications.waset.org/abstracts/search?q=Arusiaba"> Arusiaba</a>, <a href="https://publications.waset.org/abstracts/search?q=Nelson%20Chijioke"> Nelson Chijioke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study was investigated to determine the growth performance , haematological and serum biochemistry of broiler fed graded levels of cocoyam (Xanthosoma sagittifolium). One hundred and twenty (120) day old broiler chicks of Anak strain were used for the study. The birds were randomly divided into 4 treatment groups of 30 birds per group, and each group was further divided into 3 replicates of 10 birds per replicate in group. Cooked cocoyam was used to formulate diets at inclusion levels of 0.00% for T1 (control), while T2, T3 and T4 contained 10.00%, 20.00% and 30.00% inclusion of cocoyam in partial replacement of maize in a Completely Randomized Design (CRD). At the end of the research, the haematological indices of broiler showed that packed cell volume (PCV) of birds fed diets 1(42.26%) and 3 (42.42%) were significantly (p<0.05) higher than birds fed diets 2 (39.72%) and 4 (38.78%).The Haemoglobin (Hb) of birds fed diets 3 (12.58g/dl) and 4 (12.26g/dl) were significantly (p<0.05) higher than birds fed diets 1 (11.60g/dl) and 2 (11.42g/dl). The values of the white blood cell (WBC) of the broiler chickens placed on cocoyam diet increased significantly (P<0.05) compared with the values obtained in the control (T1) . The serum protein value for birds fed diet I (5.45g/dl) were statistically (P>0.05) similar to those fed diets 2 (5.10g/dl) and 3 (5.38g/dl) but differ significantly (P<0.05) from diet 4 (4.97g/dl) which had the least protein value. Final weight of the birds showed that diet 4 (2370.85g) had the highest (P<0.05) value which was followed closely by diet 3 (2225.55g), while birds fed diets 1 (2165.70g) and diet 2 (2145.00g) recorded the least values Similar pattern was observed in the weight gain of the birds. Birds fed diet 4 (2270.30g) had higher (P<0.05) value, followed by birds on diet 3 (2125.45g), while birds fed diet 1 (2065.15g) and 2 (2044.90g) had the least values.. This study showed that birds fed diet 3 (50.60g) and diet 4 (54.05g) gave significantly (P<0.05) higher weight than the control diet (49.17g). There was significant (P<0.05) difference among the treatments for feed conversion ratio (FCR), were birds fed diet 4 (1.74) performed better, having the least feed conversion ratio. Economics of broiler chickens showed that Cost/kg of feed favored diet 4 (₦158.65) followed by diets 3 (₦165.95), 2 (₦178.52) and control diet 1 (₦197.14). From the result, the higher weight recorded in T4 4 showed that cocoyam meal can successfully replace maize up to 30% in the diet of broiler chickens. The low cost recorded in cocoyam based diets showed that the diets were more economical and beneficial compared to control diet 1. Therefore, feeding diet 4 (30%) cocoyam meal as replacement of maize in broiler chickens is recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cocoyam" title="cocoyam">cocoyam</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=heamatology" title=" heamatology"> heamatology</a>, <a href="https://publications.waset.org/abstracts/search?q=serum%20biochemistry" title=" serum biochemistry"> serum biochemistry</a> </p> <a href="https://publications.waset.org/abstracts/167704/growth-performancehaematological-and-serum-biochemistry-of-broilers-fed-graded-levels-of-cocoyam-xanthosoma-sagittifolium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167704.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">116</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">268</span> Avifaunal Diversity in the Mallathahalli Lake of Bangalore Urban District, Karnataka, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vidya%20Padmakumar">Vidya Padmakumar</a>, <a href="https://publications.waset.org/abstracts/search?q=N.%20C.%20Tharavathy"> N.

During the study period, 46 species of both terrestrial, as well as, aquatic birds belonging to 30 families were identified out of which 9 families were aquatic birds and 21 families were terrestrial birds. There were 4 species of migratory birds out of 46, showing diurnal migration. There was a significant reduce in the number of bird species both terrestrial and aquatic during the summer season and also varied greatly during winters and monsoon. Of the total 24 species of aquatic birds, Fulica atra and Tachybaptus ruficolis were the most common with 100% frequency and the least frequent species with 3.02% frequency was identified as Threskiornis melanocephalus. Among the 22 species of terrestrial birds, Acridotheres tristis had a frequency of 89% and the least frequent was Pycnonotus cafer (4.45%). The most commonly encountered bird species were from the families- Anatidae, Podicipedidae, Ardeidae, Phalacrocoracidae, Rallidae, Accipitridae, Scolopacidae, Charadridae, Laridae, Meropidae, Hirudinidae. All the birds surviving around the area are dependent on the wetland and crop vegetation surrounding the lake, which are deteriorating due to anthropogenic interventions and urbanization which are rising to its peak gradually causing the decline in the avifaunal diversity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Avifaunal%20diversity" title="Avifaunal diversity">Avifaunal diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=Mallathahalli%20lake" title=" Mallathahalli lake"> Mallathahalli lake</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonal%20migration" title=" seasonal migration"> seasonal migration</a>, <a href="https://publications.waset.org/abstracts/search?q=urbanization" title=" urbanization"> urbanization</a> </p> <a href="https://publications.waset.org/abstracts/87938/avifaunal-diversity-in-the-mallathahalli-lake-of-bangalore-urban-district-karnataka-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87938.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">179</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">267</span> Species Diversity of Migratory Birds along Boat Touring Routes in Klong Kone Sub-District, Muang District, Samut Songkram Province, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Chitman">P.

Wind turbines are installed in more and more challenging locations, often close to the natural environment of birds. More and more countries and organizations are defining guidelines for the necessary functionality of such systems. The minimum bird detection distance, trajectory tracking, and shutdown time are key factors in eliminating collisions. Since 2020, we have continued the survey on the validation of the subsequent version of the BPS detection and reaction system. Bird protection system (BPS) is a fully automatic camera system which allows one to estimate the distance of the bird to the turbine, classify its size and autonomously undertake various actions depending on the bird's distance and flight path. The BPS was installed and tested in a real environment at a wind turbine in northern Poland and Central Spain. The performed validation showed that at a distance of up to 300 m, the BPS performs at least as well as a skilled ornithologist, and large bird species are successfully detected from over 600 m. In addition, data collected by BPS systems installed in Spain showed that 60% of the detections of all birds of prey were from individuals approaching the turbine, and these detections meet the turbine shutdown criteria. Less than 40% of the detections of birds of prey took place at wind speeds below 2 m/s while the turbines were not working. As shown by the analysis of the data collected by the system over 12 months, the system classified the improved size of birds with a wingspan of more than 1.1 m in 90% and the size of birds with a wingspan of 0.7 - 1 m in 80% of cases. The collected data also allow the conclusion that some species keep a certain distance from the turbines at a wind speed of over 8 m/s (Aquila sp., Buteo sp., Gyps sp.), but Gyps sp. and Milvus sp. remained active at this wind speed on the tested area. The data collected so far indicate that BPS is effective in detecting and stopping wind turbines in response to the presence of birds of prey with a wingspan of more than 1 m. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=protecting%20birds" title="protecting birds">protecting birds</a>, <a href="https://publications.waset.org/abstracts/search?q=birds%20monitoring" title=" birds monitoring"> birds monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20farms" title=" wind farms"> wind farms</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20energy" title=" green energy"> green energy</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a> </p> <a href="https://publications.waset.org/abstracts/162657/artificial-intelligence-protecting-birds-against-collisions-with-wind-turbines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162657.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">76</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">264</span> Artificial Nesting in Birds at UVAS-Ravi Campus: Punjab-Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Chaudhary">Fatima Chaudhary</a>, <a href="https://publications.waset.org/abstracts/search?q=Rehan%20Ul%20Haq"> Rehan Ul Haq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Spatial and anthropogenic factors influencing nest-site selection in birds need to be identified for effective conservative practices. Environmental attributes such as food availability, predator density, previous reproductive success, etc., provide information regarding the site's quality. An artificial nest box experiment was carried out to evaluate the effect of various factors on nest-site selection, as it is hard to assess the natural cavities. The experiment was conducted whereby half of the boxes were filled with old nest material. Artificial nest boxes created with different materials and different sizes and colors were installed at different heights. A total of 14 out of 60 nest boxes were occupied and four of them faced predation. The birds explored a total of 32 out of 60 nests, whereas anthropogenic factors destroyed 25 out of 60 nests. Birds chose empty nest boxes at higher rates however, there was no obvious avoidance of sites having high ectoparasites load due to old nest material. It is also possible that the preference towards the artificial nest boxes may differ from year to year because of several climatic factors and the age of old nest material affecting the parasite's survival. These variables may fluctuate from one season to another. Considering these factors, nest-site selection experiments concerning the effectiveness of artificial nest boxes should be carried out over several successive seasons. This topic may stimulate further studies, which could lead to a fully understanding the birds' evolutionary ecology. Precise information on these factors influencing nest-site selection can be essential from an economic point of view as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20nesting" title="artificial nesting">artificial nesting</a>, <a href="https://publications.waset.org/abstracts/search?q=nest%20box" title=" nest box"> nest box</a>, <a href="https://publications.waset.org/abstracts/search?q=old%20nest%20material" title=" old nest material"> old nest material</a>, <a href="https://publications.waset.org/abstracts/search?q=birds" title=" birds"> birds</a> </p> <a href="https://publications.waset.org/abstracts/164894/artificial-nesting-in-birds-at-uvas-ravi-campus-punjab-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164894.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">93</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">263</span> Efficacy of Vitamins A, C and E on the Growth Performance of Broiler Chickens Subjected to Heat Stress</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Desierin%20Rodrin">Desierin Rodrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Alcantara"> Magdalena Alcantara</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristina%20Olo"> Cristina Olo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increase in environmental temperatures brought about by climate change impacts negatively the growth performance of broilers that may be solved by manipulating the diet of the animals. Hence, this study was conducted to evaluate the effects of different vitamin supplements on the growth performance of broiler chickens subjected to ambient (31°C) and heat stress (34°C) temperatures. The treatments were: I- Control (no vitamin supplement), II- Vitamin A (4.5 mg/kg of feed), III- Vitamin C (250 mg/kg of feed), IV- Vitamin E (250 mg/kg of feed), V- Vitamin C and E (250 mg/kg of feed and 250 mg/kg of feed), VI- Vitamin A and E (4.5 mg/kg of feed and 250 mg/kg of feed), VII- Vitamin A and C (4.5 mg/kg of feed and 250 mg/kg of feed), and VIII- Vitamin A, C and E (4.5 mg/kg of feed, 250 mg/kg of feed and 250 mg/kg of feed). The birds (n=240) were distributed randomly into eight treatments replicated three times, with each replicates having five birds. Ambient temperature was maintained using a 25 watts bulb for every 20 birds, while heat stress condition was sustained at 34°C for about 9 hours daily by using a 50 watts bulb per 5 birds. The interaction of vitamin supplements and temperatures did not significantly (P>0.05) affected body weight, average daily gain, feed consumption and feed conversion efficiency throughout the growing period. Similarly, supplementation of different vitamins did not improve (P>0.05) the overall production performance of birds throughout the rearing period. Birds raised in heat stress (34°C) condition had significantly lower ((P<0.05) body weight, average daily gain, and feed consumption compared to birds raised in ambient temperature at weeks 3, 4 and 5 of rearing. Supplementation of vitamins A, C, and E in the diet of broilers did not alleviate the effect of heat stress in the growth performance of broilers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broiler%20growth%20performance" title="broiler growth performance">broiler growth performance</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20stress" title=" heat stress"> heat stress</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20supplementation" title=" vitamin supplementation"> vitamin supplementation</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=vitamin%20C" title=" vitamin C"> vitamin C</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20E" title=" vitamin E"> vitamin E</a> </p> <a href="https://publications.waset.org/abstracts/68238/efficacy-of-vitamins-a-c-and-e-on-the-growth-performance-of-broiler-chickens-subjected-to-heat-stress" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68238.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">292</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">262</span> Density of Introduced Birds (Sturnidae: Mynas) in Urban Areas of Kuching and Samarahan, Sarawak, Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Abdul%20Rahman">Mustafa Abdul Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Maisarah%20Abdullah"> Maisarah Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurfarahin%20Azizan"> Nurfarahin Azizan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd-Azlan%20Jayasilan"> Mohd-Azlan Jayasilan</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Alek%20Tuen"> Andrew Alek Tuen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Common myna (Acridotheres tristis) and Javan myna (A. javanicus) belong to the family Sturnidae. These two species range from Iran, Afghanistan, and east through the Indian subcontinent to south China, Indochina and the mainland Southeast Asia. It was introduced to Sarawak in 1980’s and since then the population has increased tremendously. A study to determine the density of these two species was conducted in the Kuching and Samarahan Districts, Sarawak, Malaysian Borneo between November 2013 and January 2014. In Kuching City a total of 12 transect lines of 500 m each were established totaling 6 km. In Samarahan District, six 500 m transect lines were established both within Universiti Malaysia Sarawak (UNIMAS) campus and in Serian Town totaling 6 km. The results showed that the density of Javan myna in Kuching City (east) was 13.9 birds/ha, Kuching City (center) was 21.3 birds/ha and Kuching City (west) was 43.1 birds/ha. The density of common myna at UNIMAS campus was 20.3 birds/ha and Serian Town was 13.2 birds/ha. The density of human population probably plays an important role in determining the density of mynas in an area as it is associated with the availability of food sources, roosting and nesting places originating from human activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=density" title="density">density</a>, <a href="https://publications.waset.org/abstracts/search?q=myna" title=" myna"> myna</a>, <a href="https://publications.waset.org/abstracts/search?q=transect" title=" transect"> transect</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive" title=" invasive"> invasive</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarawak" title=" Sarawak"> Sarawak</a>, <a href="https://publications.waset.org/abstracts/search?q=Borneo" title=" Borneo"> Borneo</a> </p> <a href="https://publications.waset.org/abstracts/25993/density-of-introduced-birds-sturnidae-mynas-in-urban-areas-of-kuching-and-samarahan-sarawak-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25993.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">574</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">261</span> Surveillance of Mycoplasma gallisepticum in Pet, Game and Free Flying Birds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shamas%20Ul%20Hassan">Shamas Ul Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasir%20Mukhtar"> Nasir Mukhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajjad%20Ur%20Rehman"> Sajjad Ur Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Asghar%20Ali%20Mian"> Asghar Ali Mian</a>, <a href="https://publications.waset.org/abstracts/search?q=Iftikhar%20Hussain"> Iftikhar Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Safdar%20Anjum"> Muhammad Safdar Anjum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Mycoplasma gallisepticum (MG) is the major cause of economic looses in birds which is transmitted by free flying birds in the environment. These demands for improving the biosecurity measures at farm level including proper disposal of farm mortality and other wastes along with the inclusion of zoos and wild life parks in the MG surveillance programme. For the purpose of doing surveillance of MG in different pet, game and free flying birds a total of 12 samples each of peacocks, pheasants, ducks, pigeons, parrots, and house crows were included in the first ever study of its nature in Pakistan. During the study, the relevant samples along with recording clinical and postmortem findings were subjected to sero-prevalence, culture isolation and PCR system. Further PCR being more sensitive proves to be a better epidemiological tool. Seropositive findings revealed in peacocks, pheasants, ducks, pigeons, parrots, and crows were 66.7%, 58.3%, 41.7%, 41.7%, 16.7% and 16.7% respectively with some free flying birds giving ambiguous reactions. Whereas in the same order the culture/isolation positive results were recorded as 25%, 16.7%, 8.3%, 16.7%, 16.7%, and 25%. The samples were further confirmed on the basis of 732 bp product in PCR system. High rate of prevalence of MG in the pet, game and free flying birds regardless to their clinical findings demands to improve the biosecurity measures at the farm level with the minimum interaction of these birds with commercial poultry. Further the proper and timely disposal of all sorts of carcasses contaminated litter and wasted feed in such ways that the free flying birds are denied of picking up at those wastages. Moreover, MG surveillance system including the advances diagnostic techniques in wildlife parks and zoos be devised with proper timely preventive and therapeutic measures. The study proves that a variety of birds other then chicken either with or without clinical exhibitions carry MG organism which could be the potential source of infection for commercial poultry. The routine surveillance will be done to reduce the economic losses in poultry production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title="epidemiology">epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=Mycoplasma%20gallisepticum%20%28MG%29" title=" Mycoplasma gallisepticum (MG)"> Mycoplasma gallisepticum (MG)</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20flying%20birds" title=" free flying birds"> free flying birds</a>, <a href="https://publications.waset.org/abstracts/search?q=surveillance" title=" surveillance"> surveillance</a>, <a href="https://publications.waset.org/abstracts/search?q=PCR" title=" PCR"> PCR</a> </p> <a href="https://publications.waset.org/abstracts/36811/surveillance-of-mycoplasma-gallisepticum-in-pet-game-and-free-flying-birds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36811.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">420</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">260</span> The Effect of Protexin and Curcuma Longa on Growth Performance, Serum Lipid and Immune Organ Weight of Broilers at Starter Period</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Ahmadi">Farhad Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Mohammadi%20Khah"> Mehran Mohammadi Khah</a>, <a href="https://publications.waset.org/abstracts/search?q=Fariba%20Rahimi"> Fariba Rahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=N.%20Vejdani%20Far"> N.

The use of enzymes and probiotics is becoming prominent due to the ban on antibiotics as growth promoters in many parts of the world. It is conceived that with enzymes and probiotics additives, fibrous leafy vegetables can be incorporated into poultry feeds as protein source. However, certain antinutrients were also found in the leaves of <em>Telfairia occidentalis</em>. Four broiler starter and finisher diets were formulated for the two phases of the broiler experiments. A mixture of fiber degrading enzymes, Roxazyme G2 (combination of cellulase, glucanase and xylanase) and probiotics (<em>Turbotox), </em>a growth promoter, were used in broiler diets at 1:1. The Roxazyme G2/<em>Turbotox</em> mixtures were used in diets containing four varying levels of <em>Telfairia occidentalis</em> leaf meal (TOLM) at 0, 10, 20 and 30%. Diets 1 were standard broiler diets without TOLM and Roxazyme G2 and <em>Turbotox</em> additives. Diets 2, 3 and 4 had enzymes and probiotics additives. Certain mineral elements such as Ca, P, K, Na, Mg, Fe, Mn, Cu and Zn were found in notable quantities viz. 2.6 g/100 g, 1.2 g/100 g, 6.2 g/100 g, 5.1 g/100 g, 4.7 g/100 g, 5875 ppm, 182 ppm, 136 ppm and 1036 ppm, respectively. Phytin, phytin-P, oxalate, tannin and HCN were also found in ample quantities viz. 189.2 mg/100 g, 120.1 mg/100 g, 80.7 mg/100 g, 43.1 mg/100 g and 61.2 mg/100 g, respectively. The average weight gain was highest at 46.3 g/bird/day for birds on 10% TOLM diet but similar (P > 0.05) to 46.2 g/bird/day for birds on 20% TOLM. The feed conversion ratio (FCR) of 2.27 was the lowest and optimum for birds on 10% TOLM although similar (P > 0.05) to 2.29 obtained for birds on 20% TOLM. FCR of 2.61 was the highest at 2.61 for birds on 30% TOLM diet. The lowest FCR of 2.27 was obtained for birds on 10% TOLM diet although similar (P > 0.05) to 2.29 for birds on 20% TOLM diet. Most carcass characteristics and organ weights were similar (P > 0.05) for the experimental birds on the different diets except for kidney, gizzard and intestinal length. The values for kidney, gizzard and intestinal length were significantly higher (P < 0.05) for birds on the TOLM diets. The nitrogen retention had the highest value of 72.37 ± 0.10% for birds on 10% TOLM diet although similar (P > 0.05) to 71.54 ± 1.89 obtained for birds on the control diet without TOLM and enzymes/probiotics mixture. There was evidence of a better utilization of TOLM as a plant protein source. The carcass characteristics and organ weights all showed evidence of uniform tissue buildup and muscles development particularly in diets containing 10% of TOLM level. There was also better nitrogen utilization in birds on the 10% TOLM diet. Considering the cheap cost of TOLM, it is envisaged that its introduction into poultry feeds as a plant protein source will ultimately reduce the cost of poultry feeds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Telfairia%20occidentalis%20leaf%20meal" title="Telfairia occidentalis leaf meal">Telfairia occidentalis leaf meal</a>, <a href="https://publications.waset.org/abstracts/search?q=enzymes" title=" enzymes"> enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotics" title=" probiotics"> probiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=additives" title=" additives"> additives</a> </p> <a href="https://publications.waset.org/abstracts/122958/improving-the-utilization-of-telfairia-occidentalis-leaf-meal-with-cellulase-glucanase-xylanase-combination-and-selected-probiotic-in-broiler-diets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122958.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">136</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">258</span> Full Fat Soybean Meal as a Substitute for Soybean Meal in Broiler Rations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20M.%20K.%20S.%20Chandana">R.

Although some local FFSBM is available, their use has not been assessed experimentally. This study was carried out to evaluate the use of local extruded FFSBM in broiler rations. Four treatment diets were formulated by incorporating locally produced FFSBM (0, 10, 20, and 30%) as a replacement for soybean meal (SBM) in a two-phase (starter and finisher) feeding program. Two hundred Hubbard F 15 day old broiler chicks were randomly assigned into four treatments with five replicates per each. Bodyweight gain (BWG), feed intakes (FI), and feed conversion ratio (FCR) were calculated for a period of 42 days. Nutrient utilization in the form of dry matter (DM), energy, nitrogen, and fat retention were estimated by the total collection method in three weeks old broilers. At the end of the experiment, carcass weight was measured, and the dressing percentage was calculated. Data were analyzed using one way analysis of variance (ANOVA) in SAS. There was no significant effect of FFSBM on feed intakes of chicks fed different diets (p > 0.05). Birds fed the control diet, and FF10 (10% FFSBM diet) gained significantly more than that of birds fed FF20 or FF30 diets (p > 0.05). In the finisher period, control birds gained more than all the other treatment birds. FCR was poorer in bird fed higher levels of FFSBM compared to the control or FF10 birds during their early life, but that was not evident in the latter part of the experiment. Treatments did not alter (p > 0.05) the retention of DM and nitrogen, but energy utilization was lowest (p < 0.05) in birds fed with 0% FFSBM, and the highest fat digestibility was observed in birds fed with 30% FFSBM diets. Thus, it can be concluded that FFSBM can be used as a substitute for SBM in broiler rations and could be incorporated up to 10% of the diet safely with no adverse effects on broiler performances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body%20weight" title="body weight">body weight</a>, <a href="https://publications.waset.org/abstracts/search?q=broiler" title=" broiler"> broiler</a>, <a href="https://publications.waset.org/abstracts/search?q=digestibility" title=" digestibility"> digestibility</a>, <a href="https://publications.waset.org/abstracts/search?q=full%20fat%20soybean%20meal" title=" full fat soybean meal"> full fat soybean meal</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean%20meal" title=" soybean meal"> soybean meal</a> </p> <a href="https://publications.waset.org/abstracts/123140/full-fat-soybean-meal-as-a-substitute-for-soybean-meal-in-broiler-rations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123140.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">149</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">257</span> Haematology and Serum Biochemical Profile of Laying Chickens Reared on Deep Litter System with or without Access to Grass or Legume Pasture under Humid Tropical Climate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Oke">E.

However, there is a paucity of data on the relative benefits of grass and legume pastures. An experiment was conducted to determine the effects of rearing systems {deep litter system (DL), deep litter with access to legumes (LP) or grass (GP) pastures} haematology and serum chemistry of ISA Brown layers. The study involved the use of two hundred and forty 12 weeks old pullets. The birds were reared until 60 weeks of age. Eighty birds were assigned to each treatment; each treatment had four replicates of 20 birds each. Blood samples (2.5 ml) were collected from the wing vein of two birds per replicate and serum chemistry and haematological parameters were determined. The results showed that there were no significant differences between treatments in all the parameters considered at 18 weeks of age. At 24 weeks old, the percentage of heterophyl (HET) in DL and LP were similar but higher than that of GP. The ratio of H:L was higher (P<0.05) in DL than those of LP and GP while LP and GP were comparable. At week 38 of age, the percentage of PCV in the birds in LP and GP were similar but the birds in DL had significantly lower level than that of GP. In the early production phase, serum total protein of the birds in LP was similar to that of GP but higher (P<0.05) than that of DL. At the peak production phase (week 38), the total protein in GP and DL were similar but significantly lower than that of LP. The albumin level in LP was greater (P<0.05) than GP but similar to that of DL. In the late production phase, the total protein in LP was significantly higher than that of DL but similar to that of GP. It was concluded that rearing chickens in either grass or legume pasture did not have deleterious effects on the health of laying chickens but improved some parameters including blood protein and HET/lymphocyte. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rearing%20systems" title="rearing systems">rearing systems</a>, <a href="https://publications.waset.org/abstracts/search?q=stylosanthes" title=" stylosanthes"> stylosanthes</a>, <a href="https://publications.waset.org/abstracts/search?q=cynodon%20serum%20chemistry" title=" cynodon serum chemistry"> cynodon serum chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=haematology" title=" haematology"> haematology</a>, <a href="https://publications.waset.org/abstracts/search?q=hen" title=" hen"> hen</a> </p> <a href="https://publications.waset.org/abstracts/51059/haematology-and-serum-biochemical-profile-of-laying-chickens-reared-on-deep-litter-system-with-or-without-access-to-grass-or-legume-pasture-under-humid-tropical-climate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51059.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">327</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">256</span> Effect of L-Dopa on Performance and Carcass Characteristics in Broiler Chickens </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20R.%20O.%20Omidiwura">B.

However, the L-Dopa in mucuna seed, when present with other antinutritional factors, causes nutritional disorders in monogastric animals. Information on the utilisation of pure L-Dopa in monogastric animals is scanty. Therefore, effect of L-Dopa on growth performance and carcass characteristics in broiler chickens was investigated. Two hundred and forty one-day-old chicks were allotted to six treatments, which consisted of a positive control (PC) with standard energy (3100Kcal/Kg) and negative control (NC) with high energy (3500Kcal/Kg). The rest 4 diets were NC+0.1, NC+0.2, NC+0.3 and NC+0.4% L-Dopa, respectively. All treatments had 4 replicates in a completely randomized design. Body weight gain, final weight, feed intake, dressed weight and carcass characteristics were determined. Body weight gain and final weight of birds fed PC were 1791.0 and 1830.0g, NC+0.1% L-Dopa were 1827.7 and 1866.7g and NC+0.2% L-Dopa were 1871.9 and 1910.9g respectively, and the feed intake of PC (3231.5g), were better than other treatments. The dressed weight at 1375.0g and 1357.1g of birds fed NC+0.1% and NC+0.2% L-Dopa, respectively, were similar but better than other treatments. Also, the thigh (202.5g and 194.9g) and the breast meat (413.8g and 410.8g) of birds fed NC+0.1% and NC+0.2% L-Dopa, respectively, were similar but better than birds fed other treatments. The drum stick of birds fed NC+0.1% L-Dopa (220.5g) was observed to be better than birds on other diets. Meat to bone ratio and relative organ weights were not affected across treatments. L-Dopa extract, at levels tested, had no detrimental effect on broilers, rather better bird performance and carcass characteristics were observed especially at 0.1% and 0.2% L-Dopa inclusion rates. Therefore, 0.2% inclusion is recommended in diets of broiler chickens for improved performance and carcass characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broilers" title="broilers">broilers</a>, <a href="https://publications.waset.org/abstracts/search?q=carcass%20characteristics" title=" carcass characteristics"> carcass characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=l-dopa" title=" l-dopa"> l-dopa</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a> </p> <a href="https://publications.waset.org/abstracts/39972/effect-of-l-dopa-on-performance-and-carcass-characteristics-in-broiler-chickens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39972.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">309</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">255</span> Potential Impacts of Invasive House Crows (Corvus splendens) Bird Species in Ismailia Governorate, Egypt: Ecology, Control and Risk Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atef%20Mohamed%20Kamel%20Ahmed">Atef Mohamed Kamel Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> House crows (Corvus splendens) have become well-established in Ismailia Governorate, Egypt, where they pose several and serious impacts on native biodiversity, ecosystems and humans health. However, there is a lack of literature on the status and effects of invasive birds in Egypt. Over the past 10 years in Ismailia, House crow have increased at a rate approaching (60000 birds)15% per annum; if this were allowed to continue, the population now 10909 birds and will exceed more by 2013, probably accompanied by an increase in geographical distribution in all Suez canal regions and an exacerbation of the problems caused. Population control is recommended, involving improvements in urban hygiene and the capture of adult crows using stupefying baits. Suitable baits and stupefacient doses were identified and these should be used annually, just before the breeding season. Control should be accompanied by studies of relevant aspects of the biology of house crows in Ismailia Governorate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20impact%20t" title="environmental impact t">environmental impact t</a>, <a href="https://publications.waset.org/abstracts/search?q=non-native%20invasive%20species" title=" non-native invasive species"> non-native invasive species</a>, <a href="https://publications.waset.org/abstracts/search?q=House%20crow%20birds" title=" House crow birds"> House crow birds</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismailia-Egypt" title=" Ismailia-Egypt"> Ismailia-Egypt</a> </p> <a href="https://publications.waset.org/abstracts/4001/potential-impacts-of-invasive-house-crows-corvus-splendens-bird-species-in-ismailia-governorate-egypt-ecology-control-and-risk-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4001.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">472</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">254</span> Designing Bird-Friendly Kolkata city</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madhumita%20Roy">Madhumita Roy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Kolkata, the city of joy, is an organic city with 45 lakhs of people till date. The increasing population stress is creating a constant pressure on the ground surface which in turn reducing the possible area for plantation. Humans, plants, and birds have a mutualistic relationship, and all are dependent on each other for their survival. Vegetation structure is very important for a bird life because it can be used as a residence, foraging, life cycle, and shelter from predators. On the other hand, in urban areas, buildings and structures also plays a major role for birds habitat w.r.t, nesting, resting, etc. City birds are constantly upgrading their adaptative mechanism with changing urban pattern with modern architectural designs. Urbanisation and unplanned development lead to environmental degradation and bird habitat fragmentation, which have impacts on the degradation of the quality and quantity of bird habitat. Declining green cover and habitat loss affects the diversity and population structure of birds. Their reducing number is an increasing threat not only to the bird community but also to the city as birds are considered as one of the most important environmental indicator. This study aims to check the present avian status like species richness, relative abundance, and diversity of bird species in the context of changing urban pattern in Kolkata city. Nesting strategy in the urban habitat of the avian community is another avenue of interest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urbanisation" title="urbanisation">urbanisation</a>, <a href="https://publications.waset.org/abstracts/search?q=avian%20species" title=" avian species"> avian species</a>, <a href="https://publications.waset.org/abstracts/search?q=kolkata%20metropolis" title=" kolkata metropolis"> kolkata metropolis</a>, <a href="https://publications.waset.org/abstracts/search?q=planning" title=" planning"> planning</a> </p> <a href="https://publications.waset.org/abstracts/154202/designing-bird-friendly-kolkata-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154202.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">100</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">253</span> Hematological and Biochemical Indices of Starter Broiler Chickens Fed African Black Plum Seed Nut (Vitex Doniana) Meal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Obadire%20F.%20O.">Obadire F.

A total of 150- 1day-old, male Agrited birds were reared for 28 days of the experiment. The birds were assigned to five dietary treatments, with ten birds per treatment replicated 3 times. Experimental diets were formulated by supplementing the milled African black plum nut at (0, 5, 10, 12.5, and 15%) inclusion levels in the starter broiler’s ratio designated as T1 (control diet containing no ABPBD), Treatments (T2, 3,4 and 5) contained ABPNBD at 5, 10, 12.5, and 15%, respectively, in a completely randomized design. The hematological and biochemical indices of the birds were determined. The result revealed that all hematological parameters measured were significant (P <0.05) except for WBC. Increasing inclusion levels of ABPNBD decreased the PCV, HB, and RBC of the birds across the treatment groups. Birds fed 12.5 and 15% ABPNBD diets recorded the least of the parameters. The result of the serum biochemical indices showed significant (P < 0.05) influence for all parameters measured except for alanine transaminase (ALT), (AST), and creatinine. The total protein (TP), albumin, globulin, and glucose values were reduced across the treatment group as ABPNBD inclusion increased. Birds fed above 10% ABPNBD recorded the lowest value of TP, albumin, globulin, and glucose when compared with birds on a control diet and other treatments. The uric acid ranged from 3.85 to 2 .13 mmol/L, while creatinine ranged from 62.00 to 53.50 mmol/l. AST ranged between 8.50 u/l (5%) to 7.90 u/l (10%). ALT ranged between 7.50 u/l (12.5%) to 5.50 u/l (5 and 10%). In conclusion, dietary inclusion of African black plum up to 10% has no detrimental effect on the health of the starter chickens. Meanwhile, inclusion above 10% revealed a negative effect on some blood parameters measured. Therefore, African black plum should be supplemented with probable probiotics or subjected to different processing methods if to be used at a 15% inclusion level for optimal results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=African%20black%20plum%20seed" title="African black plum seed">African black plum seed</a>, <a href="https://publications.waset.org/abstracts/search?q=starter%20broiler%20chickens" title=" starter broiler chickens"> starter broiler chickens</a>, <a href="https://publications.waset.org/abstracts/search?q=hematological%20and%20serum%20biochemical%20indices" title=" hematological and serum biochemical indices"> hematological and serum biochemical indices</a>, <a href="https://publications.waset.org/abstracts/search?q=%28Vitex%20doniana%29" title=" (Vitex doniana)"> (Vitex doniana)</a> </p> <a href="https://publications.waset.org/abstracts/185119/hematological-and-biochemical-indices-of-starter-broiler-chickens-fed-african-black-plum-seed-nut-vitex-doniana-meal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185119.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">52</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">252</span> Assessment of Population Trends of Birds at Taunsa Barrage Wildlife Sanctuary, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fehmeada%20Bibi">Fehmeada Bibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shafqat%20Nawaz%20Qaisrani"> Shafqat Nawaz Qaisrani</a>, <a href="https://publications.waset.org/abstracts/search?q=Masood%20Akhtar"> Masood Akhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Zulfiqar%20Ali"> Zulfiqar Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Population trends learning is an important tool for conservation programs in rare as well as in common species of birds. A study was conducted to assess annual decline in species of birds and to identify the causes of this decline at Taunsa Barrage wildlife Sanctuary, Punjab, Pakistan. Data were collected by direct census method during wintering and breeding periods (2001 to 2002 and 2008 to 2011). The results indicated an increasing trend in 157, whereas a decreasing trend in 14 species of birds. Among the species with declining trend, there was a 92% decrease in White-backed Vulture (Gyps bengalensis), 60% in Greater Painted Snipe (Rostratula benghalensis), 57% in Garganey (Anas querquedula), Pallas’s Fish Eagle and Long-legged Buzzard (Buteo rufinus) 50% each, 41% in Grey Heron (Ardea cinerea), 39% in Little Cormorant (Phalacrocorax niger), 37% in Gadwall (Anas strepera), 33% in Marsh Harrier (Circus aeruginosus), 30% in Black Drongo (Dicrurus macrocercus) and 26% in Red-crested Pochard (Netta rufina) population. Habitat exploitation, hunting and grazing were found the main causes of this decline. In conclusion, conservation and management of the study area is foremost to interests of declining bird population. It is suggested, therefore, to take immediate steps for the protection of the sanctuary to conserve the declining population of birds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=population%20trends" title="population trends">population trends</a>, <a href="https://publications.waset.org/abstracts/search?q=wildlife%20sanctuary" title=" wildlife sanctuary"> wildlife sanctuary</a>, <a href="https://publications.waset.org/abstracts/search?q=bird" title=" bird"> bird</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat%20exploitation" title=" habitat exploitation"> habitat exploitation</a> </p> <a href="https://publications.waset.org/abstracts/44174/assessment-of-population-trends-of-birds-at-taunsa-barrage-wildlife-sanctuary-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44174.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">275</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">251</span> Effects of Copper Oxide Nanoparticles on the Growth Performance, Antioxidant Enzymes Activity and Gut Morphology of Broiler Chickens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Nassiri">Mohammad Nassiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Ahmadi"> Farhad Ahmadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research was carried out to investigate the effects of copper oxide nanoparticles (nano-CuO) on performance and gut morphology of broiler chickens. A total of 240 one-day-old male chickens (Ross-308) were randomly divided in a completely randomized design, the inclusion of 4 groups of 60 birds with 4 replicates and 15 birds in each. Experimental diets were as follow: T1 control (basal diets, without nano-CuO but contain 9.1 mg Cu/kg from CuO), T2, T3, and T4 basal diet supplementation with 30, 60, and 90 mg nano-CuO/kg, respectively. Feed intake (FI) and gain weight as weekly recorded and on d 21 feed conversion ratio (FCR) were calculated. Furthermore, at the end of the trial (21 d), four birds per treatment (one bird/replicate) randomly selected and after removed blood samples, they slaughtered and then to the analysis of gut morphological. A segment (10 cm) from the middle part of duodenum and jejunum was removed and put in the formalin 10% (pH = 7). The results revealed that nano-CuO had significantly increased body weight (P = 0.029, but feed intake (P = 0.017), and feed conversion ratio (P = 0.031) decreased in the birds that fed 90 mg nano-CuO when compared to control and the other groups. Total antioxidant capacity (P = 0.041), superoxide dismutase (P = 0.036), and glutathione peroxidase (P = 0.048) were more in the birds fed diet inclusion of 60 and 90 mg nano-CuO (T4) than other treatments. The lowest malonaldehyde (MDA) level was observed in T3 (P = 0.23) and T4 (P = 0.028) decreased (P = 0.17). The villi height and villi height to crypt depth (VH/CD ratio) numerically increased (P = 0.09) in the bird fed 90 mg nano-CuO in comparison with other treatments. According to present results, it could be concluded that dietary nano-CuO improved performance parameters and antioxidant status of broiler chickens during starter period. As well, the optimum improvement observed in the birds fed diet inclusion of 90 mg nano-CuO/kg. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title="antioxidant">antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=broilers" title=" broilers"> broilers</a>, <a href="https://publications.waset.org/abstracts/search?q=copper" title=" copper"> copper</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/34171/effects-of-copper-oxide-nanoparticles-on-the-growth-performance-antioxidant-enzymes-activity-and-gut-morphology-of-broiler-chickens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34171.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">571</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">250</span> Radar Track-based Classification of Birds and UAVs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Altilio%20Rosa">Altilio Rosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Chirico%20Francesco"> Chirico Francesco</a>, <a href="https://publications.waset.org/abstracts/search?q=Foglia%20Goffredo"> Foglia Goffredo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, the number of Unmanned Aerial Vehicles (UAVs) has significantly increased. The rapid development of commercial and recreational drones makes them an important part of our society. Despite the growing list of their applications, these vehicles pose a huge threat to civil and military installations: detection, classification and neutralization of such flying objects become an urgent need. Radar is an effective remote sensing tool for detecting and tracking flying objects, but scenarios characterized by the presence of a high number of tracks related to flying birds make especially challenging the drone detection task: operator PPI is cluttered with a huge number of potential threats and his reaction time can be severely affected. Flying birds compared to UAVs show similar velocity, RADAR cross-section and, in general, similar characteristics. Building from the absence of a single feature that is able to distinguish UAVs and birds, this paper uses a multiple features approach where an original feature selection technique is developed to feed binary classifiers trained to distinguish birds and UAVs. RADAR tracks acquired on the field and related to different UAVs and birds performing various trajectories were used to extract specifically designed target movement-related features based on velocity, trajectory and signal strength. An optimization strategy based on a genetic algorithm is also introduced to select the optimal subset of features and to estimate the performance of several classification algorithms (Neural network, SVM, Logistic regression…) both in terms of the number of selected features and misclassification error. Results show that the proposed methods are able to reduce the dimension of the data space and to remove almost all non-drone false targets with a suitable classification accuracy (higher than 95%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=birds" title="birds">birds</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=UAVs" title=" UAVs"> UAVs</a> </p> <a href="https://publications.waset.org/abstracts/143397/radar-track-based-classification-of-birds-and-uavs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143397.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">221</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">249</span> Comparative Effects of Dietary Ocimum Gratissimum and Antibiotic Growth Promoter on Body Weight and Gut Morphometry of Broiler Starters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20U.%20Odoemelam">Victor U.

Numerous additives are now being used or proposed as alternatives. A study to compare the effects of Ocimum gratissimum (Scent leaf) and antibiotic growth promoter (Oxytetracycline HCl) on growth performance and intestinal morphology of starter broiler birds was conducted using ninety six (96) days old broiler birds. The birds were randomly assigned to four treatments with each treatment comprising 24 birds replicated three times with 8 birds per replicate in a completely randomized design experiment. Four diets (T1 control diet without Oxytetracycline HCl and Ocimum gratissimum; T2 had Oxytetracycline HCl; T3 had 1% Ocimum gratissimum; T4 had 1.5% Ocimum gratissimum) were formulated and offered ad libitum to the respective birds. Data was collected on feed intake, body weight gain and feed conversion ratio (FCR) also Jejenal sections of the intestine were collected for examination of Villi length and Crypt depth at the end of starter phase. Results show that there were no significant difference (P>0.05) observed in feed intake and final body weight. However, feed conversion ratio (FCR) and daily weight gain significantly differed (P<0.05). T1, T2, and T4 were similar, however T2 differed (P<0.05) from T3. FCR followed the same pattern. Dietary treatment significantly (P<0.05) affected Villi length, Crypt depth and Villi length/crypt depth ratio. Birds fed OG containing diets, had significantly higher (P<0.05) villi length/crypt depth ratio. However, this did not translate to a significantly higher body weight gain or feed conversion ratio. It can be concluded that O. gratissimum can replace antibiotic growth promoter (Oxytetracycline HCl) since their effect on performance were similar. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title="antibiotics">antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20weight" title=" body weight"> body weight</a>, <a href="https://publications.waset.org/abstracts/search?q=feed%20additives" title=" feed additives"> feed additives</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20morphology" title=" intestinal morphology"> intestinal morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=phytogenics" title=" phytogenics"> phytogenics</a> </p> <a href="https://publications.waset.org/abstracts/23557/comparative-effects-of-dietary-ocimum-gratissimum-and-antibiotic-growth-promoter-on-body-weight-and-gut-morphometry-of-broiler-starters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23557.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">544</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">248</span> Contribution to the Study of Reproduction of Water Birds (Case of Marsh Bouessdra, North East Algeria)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wahiba%20Boudraa">Wahiba Boudraa</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Draidi"> Khalil Draidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Badis%20Bakhouch"> Badis Bakhouch</a>, <a href="https://publications.waset.org/abstracts/search?q=Farah%20Chettibi"> Farah Chettibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Meriem%20Aberkane"> Meriem Aberkane</a>, <a href="https://publications.waset.org/abstracts/search?q=Zihad%20Bouslama"> Zihad Bouslama</a>, <a href="https://publications.waset.org/abstracts/search?q=Moussa%20Houhamdi"> Moussa Houhamdi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Gulf of Annaba, located at the extreme north eastern Algerian; our site of study is a marsh administratively it is part of the wilaya of Annaba, municipality of El-Bouni; extends on a surface from 55 hectare, the maximum depth is of less 2m. A scheme of work was adopted for an evaluation and characterization of the reproduction of the water nicheurs birds in the marsh of Boussedra. Some important parameters described by the scientific literature; According to standardized methods, variables were the object of a regular follow-up during the period of reproduction. These parameters were taken into account: the installation date of the nests, the vegetable support; blossoming of eggs, causes of the failure of the blossomings (predation or abandonment), characteristics of the nests (composition, internal diameter, external diameter, depth and heightening), measurements of the distances nest-nest nearest, Depth of water, the measurement of eggs, size of laying, size of laying. The follow-up in the marsh was carried out between March 2013 until the month of July 2014 at a rate of two outputs per weeks, one located and noted the nests to control them each week. The study on the reproduction of the water birds enables us to note that this site plays a very important part in the wintering and the reproduction of certain species important. This study opens broad prospects for study of several phenomena related to the ecology of the water birds, and the conservation of the wetlands. <p class="card-text"><strong>Keywords:</strong> <a
