evaluating the effects of grounding with copper wire on the reduction of the microbial load of biocontaminated milk samples and on their acidification over time, two complementary experiments were carried out. In the first, the treatments consisted of: i) raw milk sample (control), ii) slow pasteurization, iii) grounding with copper wire and, iv) contact with copper ring. Analyzes of total, thermoresistant and mesophilic coliforms were performed 30 minutes after the application of these treatments. In the second experiment, under the same conditions as the first, measurements of pH and Dornic acidity were performed at 0, 0.5, 2, 4, 8, 12, and 24 h from the installation of the experiment. Pasteurization eliminated almost all groups of bacteria present in the milk samples while grounding only allowed reductions in the population of thermotolerant coliforms and mesophiles, both greater than 95%, maintaining, however, unchanged the amounts of total coliforms. The copper ring, in turn, had no effect on the microbiological parameters studied. The reduction in the population of mesophiles in grounded milk samples, contrary to what happened with pasteurized milk, was not enough to inhibit the acidification process over the experimental period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pasteurization" title="pasteurization">pasteurization</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20frequency%20electric%20current" title=" low frequency electric current"> low frequency electric current</a>, <a href="https://publications.waset.org/abstracts/search?q=thermotolerant%20coliforms" title=" thermotolerant coliforms"> thermotolerant coliforms</a>, <a href="https://publications.waset.org/abstracts/search?q=mesophiles%20in%20bovine%20milk" title=" mesophiles in bovine milk"> mesophiles in bovine milk</a> </p> <a href="https://publications.waset.org/abstracts/161087/reduction-of-the-microbial-load-of-biocontaminated-bovine-milk-using-grounding-with-copper-wire" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161087.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">107</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">674</span> Conservativeness of Functional Proteins in Bovine Milk by Pulsed Electric Field Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sulhee%20Lee">Sulhee Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Geon%20Kim"> Geon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Seo%20Park"> Young-Seo Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unlike the traditional milk sterilization methods (LTLT, HTST, or UHT), pulsed electric field (PEF) technology is a non-thermal pasteurization process. This technology minimizes energy required for heat treatment in food processing, changes in sensory properties, and physical losses. In this study, structural changes of bovine milk proteins, the amount of immunoproteins such as IgG, and their storability by PEF treatment were examined. When the changes of protein content in PEF-treated milk were examined using HPLC, the amounts of α-casein and β-lactoglobulin were reduced over 40% each, whereas those of κ-casein and β-casein did not change. The amount of α-casein in HTST milk was reduced to 50%. When PEF was applied to milk at the energy level of 250 kJ, the amounts of IgG, IgA, β-lactoglobulin (β-LG), lactoferrin, and α-lactalbumin (α-LA) decreased by 43, 41, 35, 63, and 45%, respectively. When milk was sterilized by LTLT process followed by PEF process at the level of 150 kJ, the concentrations of IgG, IgA, β-LG, lactoferrin, and α-LA were 56.6, 10.6, 554, 2.8 and 660.1 μg/mL, respectively. When the bovine milk was sterilized by LTLT process followed by PEF process at the energy level of 180 kJ, storability of immunoproteins of milk was the highest and the concentrations of IgG, IgA, and β-LG decreased by 79.5, 6.5, and 134.5 μg/mL, respectively, when compared with the initial concentrations of those proteins. When bovine milk was stored at 4℃ after sterilization through HTST sterilizer followed by PEF process at the energy level of 200 kJ, the amount of lactoferrin decreased 7.3% after 36 days of storage, whereas that of lactoferrin of raw milk decreased 16.4%. Our results showed that PEF treatment did not change the protein structure nor induce protein denaturation in milk significantly when compared with LTLT or HTST sterilization. Also, LTLT or HTST process in combination with PEF were more effective than LTLT only or HTST only process in the conservation of immunoproteins in bovine milk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulsed%20electric%20field" title="pulsed electric field">pulsed electric field</a>, <a href="https://publications.waset.org/abstracts/search?q=bovine%20milk" title=" bovine milk"> bovine milk</a>, <a href="https://publications.waset.org/abstracts/search?q=immunoproteins" title=" immunoproteins"> immunoproteins</a>, <a href="https://publications.waset.org/abstracts/search?q=sterilization" title=" sterilization"> sterilization</a> </p> <a href="https://publications.waset.org/abstracts/24388/conservativeness-of-functional-proteins-in-bovine-milk-by-pulsed-electric-field-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24388.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">436</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">673</span> Analysis of Microbiological Quality and Detection of Antibiotic Residue in Bovine Raw Milk Produced in Blida State, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20N.%20Boukhatem">M.

It must meet stringent standards to ensure the highest microbiological and toxicological qualities.In order to assess the microbiological risks associated with the consumption of this food, we conducted this study to determine the microbiological quality of bovine raw milk (54 samples) commercialized at the state of Blida (Algeria). The samples analyzed were unsatisfactory in terms of total flora where 61.11% of samples were considered as non acceptable in terms of quality standards, fecal coliforms (40.74%), fecal streptococci (55.55%) and staphylococci (74.07%). Salmonella and Clostridium strains were not detected in all the samples. Furthermore, antibiotic residues were found in 26% of analysed samples. These results reflect non-compliance with the rules of good hygiene practices at milking, storage, transportatio, and sale of milk. Bovine raw milk consumed presents a serious health risk to the population of the study areas.The livestock coaching actors and dissemination of good hygiene practices throughout the production chain are needed to improve the quality of local milk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bovine%20raw%20milk" title="bovine raw milk">bovine raw milk</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiological%20quality" title=" microbiological quality"> microbiological quality</a>, <a href="https://publications.waset.org/abstracts/search?q=fecal%20coliforms" title=" fecal coliforms"> fecal coliforms</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20residue" title=" antibiotic residue"> antibiotic residue</a>, <a href="https://publications.waset.org/abstracts/search?q=Blida%20state" title=" Blida state"> Blida state</a> </p> <a href="https://publications.waset.org/abstracts/78457/analysis-of-microbiological-quality-and-detection-of-antibiotic-residue-in-bovine-raw-milk-produced-in-blida-state-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78457.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">238</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">672</span> Influence of European Funds on the Sector of Bovine Milk and Meat in Romania in the Period 2007-2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrei-Marius%20Sandu">Andrei-Marius Sandu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to analyze the bovine meat and milk sector for the period 2007-2013.

Although rennet is still the most used coagulating enzyme in cheese, its production has been growing worldwide shortage. This shortage is primarily due to a growing increase in the production and consumption of cheese, and the inability to increase in parallel the production of rennet. This shortage has caused very large fluctuations in its price). To overcome these obstacles, much research has been undertaken to find effective and competitive substitutes used industrially. For this, the selection of a local production of rennet substitute is desirable. It would allow a permanent supply with limited dependence on imports and price fluctuations. Investigations conducted by our research team showed that extracts coagulants from the stomachs of older camels are characterized by a coagulating power than those from younger camels. The objective of this work is to study the possibility of substituting commercial rennet coagulant by gastric enzymes from adult camels for coagulation bovine milk. Excerpts from the raw camel coagulants obtained are characterized through their teneures proteins and clotting and proteolytic activities. Milk clotting conditions by the action of these extracts were optimized. Milk clotting time all treated with enzyme preparations and under different conditions was calculated. Bovine rennet has been used for comparison. The results show that crude extracts from gastric adult camel can be good substituting bovine rennet. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Algeria" title="Algeria">Algeria</a>, <a href="https://publications.waset.org/abstracts/search?q=camel" title=" camel"> camel</a>, <a href="https://publications.waset.org/abstracts/search?q=cheese" title=" cheese"> cheese</a>, <a href="https://publications.waset.org/abstracts/search?q=coagulation" title=" coagulation"> coagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=gastric%20extracts" title=" gastric extracts"> gastric extracts</a>, <a href="https://publications.waset.org/abstracts/search?q=milk" title=" milk"> milk</a> </p> <a href="https://publications.waset.org/abstracts/40947/ability-of-gastric-enzyme-extract-of-adult-camel-to-clot-bovine-milk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40947.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">441</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">670</span> Determining the Presence of Brucella abortus Antibodies by the Indirect Elisa Method in Bovine Bulk Milk and Risk Factors in the Peri-Urban Zones of Bamenda Cameroon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cha-ah%20C.%20N.">Cha-ah C.

Though eradicated in some parts of the world, it remains endemic in sub-Saharan Africa including Cameroon. The aim of this study was to contribute to the epidemiology of brucellosis in the North-West region of Cameroon by detecting the presence of anti-Brucella antibodies in bovine bulk milk as this serves as a route of transmission from animals to man. A cross sectional study was conducted to determine the prevalence of Brucella abortus antibodies in bovine bulk milk in the peri-urban zones of Bamenda. One hundred bulk milk samples were collected from 100 herds and tested by milk I-ELISA test. The conducted study revealed the presence of anti-Brucella abortus antibodies in bovine bulk milk. The study revealed that bovine brucellosis is widespread in animal production systems in this area. The animal infection pressure in these systems has remained strong due to movement of livestock in search of pasture, co-existence of animal husbandry, communal sharing of grazing land, concentration of animals around water points, abortions in production systems, locality of production systems and failure to quarantine upon introduction of new animals. The circulation of Brucella abortus antibodies in cattle farms recorded in the study revealed potential public health implication and suggest economic importance of brucellosis to the cattle industry in the Northwest region of Cameroon. The risk for re-emergence and transmission of brucellosis is evident as a result of the co-existence of animal husbandry activities and social-cultural activities that promote brucellosis transmission. Well-designed countrywide, evidence-based studies of brucellosis are needed. These could help to generate reliable frequency and potential impact estimates, to identify Brucella reservoirs, and to propose control strategies of proven efficacy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brucellosis" title="brucellosis">brucellosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bulk%20milk" title=" bulk milk"> bulk milk</a>, <a href="https://publications.waset.org/abstracts/search?q=northwest%20region%20Cameroon" title=" northwest region Cameroon"> northwest region Cameroon</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence" title=" prevalence"> prevalence</a> </p> <a href="https://publications.waset.org/abstracts/94087/determining-the-presence-of-brucella-abortus-antibodies-by-the-indirect-elisa-method-in-bovine-bulk-milk-and-risk-factors-in-the-peri-urban-zones-of-bamenda-cameroon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94087.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">669</span> Transition in Protein Profile, Maillard Reaction Products and Lipid Oxidation of Flavored Ultra High Temperature Treated Milk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20%20Ajmal">Muhammad Ajmal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> - Thermal processing and subsequent storage of ultra-heat treated (UHT) milk leads to alteration in protein profile, Maillard reaction and lipid oxidation. Concentration of carbohydrates in normal and flavored version of UHT milk is considerably different. Transition in protein profile, Maillard reaction and lipid oxidation in UHT flavored milk was determined for 90 days at ambient conditions and analyzed at 0, 45 and 90 days of storage. Protein profile, hydroxymethyl furfural, furosine, Nε-carboxymethyl-l-lysine, fatty acid profile, free fatty acids, peroxide value and sensory characteristics were determined. After 90 days of storage, fat, protein, total solids contents and pH were significantly less than the initial values determined at 0 day. As compared to protein profile normal UHT milk, more pronounced changes were recorded in different fractions of protein in UHT milk at 45 and 90 days of storage. Tyrosine content of flavored UHT milk at 0, 45 and 90 days of storage were 3.5, 6.9 and 15.2 µg tyrosine/ml. After 45 days of storage, the decline in αs1-casein, αs2-casein, β-casein, κ-casein, β-lactoglobulin, α-lactalbumin, immunoglobulin and bovine serum albumin were 3.35%, 10.5%, 7.89%, 18.8%, 53.6%, 20.1%, 26.9 and 37.5%. After 90 days of storage, the decline in αs1-casein, αs2-casein, β-casein, κ-casein, β-lactoglobulin, α-lactalbumin, immunoglobulin and bovine serum albumin were 11.2%, 34.8%, 14.3%, 33.9%, 56.9%, 24.8%, 36.5% and 43.1%. Hydroxy methyl furfural content of UHT milk at 0, 45 and 90 days of storage were 1.56, 4.18 and 7.61 (µmol/L). Furosine content of flavored UHT milk at 0, 45 and 90 days of storage intervals were 278, 392 and 561 mg/100g protein. Nε-carboxymethyl-l-lysine content of UHT flavored milk at 0, 45 and 90 days of storage were 67, 135 and 343mg/kg protein. After 90 days of storage of flavored UHT milk, the loss of unsaturated fatty acids 45.7% from the initial values. At 0, 45 and 90 days of storage, free fatty acids of flavored UHT milk were 0.08%, 0.11% and 0.16% (p<0.05). Peroxide value of flavored UHT milk at 0, 45 and 90 days of storage was 0.22, 0.65 and 2.88 (MeqO²/kg). Sensory analysis of flavored UHT milk after 90 days indicated that appearance, flavor and mouth feel score significantly decreased from the initial values recorded at 0 day. Findings of this investigation evidenced that in flavored UHT milk more pronounced changes take place in protein profile, Maillard reaction products and lipid oxidation as compared to normal UHT milk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UHT%20flavored%20milk" title="UHT flavored milk ">UHT flavored milk </a>, <a href="https://publications.waset.org/abstracts/search?q=hydroxymethyl%20furfural" title=" hydroxymethyl furfural"> hydroxymethyl furfural</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20oxidation" title=" lipid oxidation"> lipid oxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=sensory%20properties" title=" sensory properties"> sensory properties</a> </p> <a href="https://publications.waset.org/abstracts/138867/transition-in-protein-profile-maillard-reaction-products-and-lipid-oxidation-of-flavored-ultra-high-temperature-treated-milk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138867.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">199</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">668</span> Staphylococcus argenteus: An Emerging Subclinical Bovine Mastitis Pathogen in Thailand </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natapol%20Pumipuntu">Natapol Pumipuntu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Staphylococcus argenteus is the emerging species of S. aureus complex. It was generally misidentified as S. aureus by standard techniques and their features. S. argenteus is possibly emerging in both humans and animals, as well as increasing worldwide distribution. The objective of this study was to differentiate and identify S. argenteus from S. aureus, which has been collected and isolated from milk samples of subclinical bovine mastitis cases in Maha Sarakham province, Northeastern of Thailand. Twenty-one isolates of S. aureus, which confirmed by conventional methods and immune-agglutination method were analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and multilocus sequence typing (MLST). The result from MALDI-TOF MS and MLST showed 6 from 42 isolates were confirmed as S. argenteus, and 36 isolates were S. aureus, respectively. This study indicated that the identification and classification method by using MALDI-TOF MS and MLST could accurately differentiate the emerging species, S. argenteus, from S. aureus complex which usually misdiagnosed. In addition, the identification of S. argenteus seems to be very limited despite the fact that it may be the important causative pathogen in bovine mastitis as well as pathogenic bacteria in food and milk. Therefore, it is very necessary for both bovine medicine and veterinary public health to emphasize and recognize this bacterial pathogen as the emerging disease of Staphylococcal bacteria and need further study about S. argenteus infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Staphylococcus%20argenteus" title="Staphylococcus argenteus">Staphylococcus argenteus</a>, <a href="https://publications.waset.org/abstracts/search?q=subclinical%20bovine%20mastitis" title=" subclinical bovine mastitis"> subclinical bovine mastitis</a>, <a href="https://publications.waset.org/abstracts/search?q=Staphylococcus%20aureus%20complex" title=" Staphylococcus aureus complex"> Staphylococcus aureus complex</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20spectrometry" title=" mass spectrometry"> mass spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=MLST" title=" MLST"> MLST</a> </p> <a href="https://publications.waset.org/abstracts/108179/staphylococcus-argenteus-an-emerging-subclinical-bovine-mastitis-pathogen-in-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108179.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">151</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">667</span> Detection of Mycobacteria spp by PCR in Raw Milk Samples Collected from Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shokoufeh%20Roudashti">Shokoufeh Roudashti</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahin%20Bahari"> Shahin Bahari</a>, <a href="https://publications.waset.org/abstracts/search?q=Fakhri%20Haghi"> Fakhri Haghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Habib%20Zeighami"> Habib Zeighami</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghazal%20Naderi"> Ghazal Naderi</a>, <a href="https://publications.waset.org/abstracts/search?q=Paniz%20Shirmast"> Paniz Shirmast</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Mycobacterium tuberculosis complex (MTBC) causes tuberculosis (TB) in humans and animals. Mycobacterium MTBC is one of the most important species of zoonotic pathogens that can be transmitted from cattle to humans. The disease can transmit to human by direct contact with the infected animals, drinking unpasteurized milk and consumption of uncooked meat. The presence of these opportunistic, pathogenic bacteria in bovine milk has emerged as a public-health concern, especially among individuals who consume raw milk. Tuberculosis MTBC is the predominant infectious cause of morbidity and morality worldwide, It is estimated that one third of the world population (approx. 1.8 billion persons) is infected with M. tuberculosis and each year there are 8 million new cases worldwide. The aim of this study, to detect Mycobacterium MTBC in raw milk samples using polymerase chain reaction (PCR). Materials and Methods: In the present study, 60 raw milk samples were collected from rural areas in Zanjan, Iran. After extraction of DNAs and using special primers for Is6110 gene as a marker, PCR was applied to detect the presence or non-presence of the related gene. Results: According to the findings of this study, 8 (13.5 %) out of 60 milk samples were positive for Mycobacterium spp (P < 0.1). Conclusions: The Outbreak of genus Mycobacteria spp in milk samples were determined to be relatively high in Zanjan, Iran. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mycobacteria%20spp" title="Mycobacteria spp">Mycobacteria spp</a>, <a href="https://publications.waset.org/abstracts/search?q=raw%20milk" title=" raw milk"> raw milk</a>, <a href="https://publications.waset.org/abstracts/search?q=PCR" title=" PCR"> PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=Zanjan" title=" Zanjan"> Zanjan</a> </p> <a href="https://publications.waset.org/abstracts/37406/detection-of-mycobacteria-spp-by-pcr-in-raw-milk-samples-collected-from-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37406.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">297</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">666</span> Sensitivity of Staphylococcus aureus Isolated from Subclinical Bovine Mastitis to Ciprofloxacin in Dairy Herd in Tabriz during 2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Jafarzadeh">Alireza Jafarzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Samad%20Mosaferi"> Samad Mosaferi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansour%20Khakpour"> Mansour Khakpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mastitis is an inflammation of the parenchyma of mammary gland regardless of the causes. Mastitis is characterized by a range of physical and chemical changes in the glandular tissue. The most important change in milk includes discoloration, the presence of clots and large number of leucocytes. There is swelling, heat, pain and edema in mammary gland in many clinical cases. Positive coagulase S. aureus is a major pathogen of the bovine mammary gland and a common cause of contagious mastitis in cattle. The aim of this study was to evaluate the outbreaks of Staphylococcus aureus mastitis. This study is conducted in ten dairy herds about one thousand cows. After doing CMT and identifying infected cows, the milk samples obtained from infected teats and transported to microbiological laboratories. After microbial culture of milk samples and isolating S. aureus, antimicrobial, sensitivity test was performed with disk diffusion method by ciprofloxacin, co-amoxiclav, erythromycin, penicillin, oxytetracyclin, sulfonamides, lincomycin and cefquinome. The study defined that the outbreak of subclinical positive coagulase Staphylococcus mastitis in dairy herd was 13.11% (5.6% S. aureus and 7.51% S. intermedicus). The antimicrobial sensitivity test shown that 87.23% of Staphylococcus aureus isolated from bovine mastitis in dairy herd was susceptible to ciprofloxacin, 93.9% to cefquinome, 4.67% to co-amoxiclav, 12.16% to erythromycin 86.11% to sulfonamides (co-trimoxazole), 3.35% lincomycin, 12.7% to oxytetracyclin and 5.98% to penicillin. Results of present defined that ciprofloxacin has a great effect on Staphylococcus aureus isolated from subclinical bovine mastitis dairy herd.

According to chemical analysis, the amount of fat, protein, and total solid was higher in buffalo milk than cow's milk (respectively, 8.2%, 4.73%, and 15.92% compared with 3.5%, 3.25%, and 12.5%). Also, the percentage of cholesterol buffalo’s milk was less than in cow's milk. In contrast, no significant difference between the pH, acidity, and specific gravity was observed. The size of buffalo milk fat globules was larger than cow's milk. In addition, the profile of buffalo free fatty acids milk showed the relatively high distribution of long chain saturated fatty acids. The presence of four major bands related to αs casein, β casein, β-lactoglobulin, and α-lactalbumin with quite higher intensity than cow’s milk was also observed.

So, the idea of instant soluble milk tablet comes into existence for its high solubility and easy handling. The moisture content of milk tablets is increased by the direct addition of water with no additives for binding. The variation of the tensile strength of instant soluble milk tablets and the flowability of milk powder with the moisture content is analyzed and optimized for the highest tensile strength of instant soluble milk tablets and flowability, above a particular value of milk powder using response surface methodology. The flowability value is necessary for ease in quantifying the milk powder, as a feed, in the designed tablet making machine. The instant soluble nature of milk tablets purely depends upon the disintegration characteristic of tablets in water whose study is under progress.

Leonard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Staphylococcus aureus is the most frequent cause of clinical and subclinical bovine mastitis in Ireland. Mastitis caused by S. aureus is often chronic and tends to recur after antibiotic treatment. This may be due to several virulence factors, including attributes that enable the bacterium to internalize into bovine mammary epithelial cells, where it may evade antibiotic treatment, or evade the host immune response. Four bovine-adapted lineages (CC71, CC97, CC151 and ST136) were identified among a collection of Irish S. aureus mastitis isolates. Genotypic variation of mastitis-causing strains may contribute to different presentations of the disease, including differences in milk somatic cell count (SCC), the main method of mastitis detection. The objective of this study was to investigate the influence of bacterial strain and lineage on host immune response, by employing cell culture methods in vitro as well as an in vivo infection model. Twelve bovine adapted S. aureus strains were examined for internalization into bovine mammary epithelial cells (bMEC) and their ability to induce an immune response from bMEC (using qPCR and ELISA). In vitro studies found differences in a variety of virulence traits between the lineages. Strains from lineages CC97 and CC71 internalized more efficiently into bovine mammary epithelial cells (bMEC) than CC151 and ST136. CC97 strains also induced immune genes in bMEC more strongly than strains from the other 3 lineages. One strain each of CC151 and CC97 that differed in their ability to cause an immune response in bMEC were selected on the basis of the above in vitro experiments. Fourteen first-lactation Holstein-Friesian cows were purchased from 2 farms on the basis of low SCC (less than 50 000 cells/ml) and infection free status. Seven cows were infected with 1.73 x 102 c.f.u. of the CC97 strain (Group 1) and another seven with 5.83 x 102 c.f.u. of the CC151 strain (Group 2). The contralateral quarter of each cow was inoculated with PBS (vehicle). Clinical signs of infection (temperature, milk and udder appearance, milk yield) were monitored for 30 days. Blood and milk samples were taken to determine bacterial counts in milk, SCC, white blood cell populations and cytokines. Differences in disease presentation in vivo between groups were observed, with two animals from Group 2 developing clinical mastitis and requiring antibiotic treatment, while one animal from Group 1 did not develop an infection for the duration of the study. Fever (temperature > 39.5⁰C) was observed in 3 animals from Group 2 and in none from Group 1. Significant differences in SCC and bacterial load between groups were observed in the initial stages of infection (week 1). Data is also being collected on cytokines and chemokines secreted during the course of infection. The results of this study suggest that a strain from lineage CC151 may cause more severe clinical mastitis, while a strain from lineage CC97 may cause mild, subclinical mastitis. Diversity between strains of S. aureus may therefore influence the clinical presentation of mastitis, which in turn may influence disease detection and treatment needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bovine%20mastitis" title="Bovine mastitis">Bovine mastitis</a>, <a href="https://publications.waset.org/abstracts/search?q=host%20immune%20response" title=" host immune response"> host immune response</a>, <a href="https://publications.waset.org/abstracts/search?q=host-pathogen%20interactions" title=" host-pathogen interactions"> host-pathogen interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=Staphylococcus%20aureus" title=" Staphylococcus aureus"> Staphylococcus aureus</a> </p> <a href="https://publications.waset.org/abstracts/86932/clinical-presentation-and-immune-response-to-intramammary-infection-of-holstein-friesian-heifers-with-isolates-from-two-staphylococcus-aureus-lineages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86932.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">157</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">660</span> Antioxidant Activity of the Algerian Traditional Kefir Supernatant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Amellal-Chibane">H.

Kefir supernatant demonstrated high antioxidant activity (87.75%) compared to the raw milk (70.59 %). These results suggest that the Algerian kefir has interesting antioxidant activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title="antioxidant activity">antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=kefir" title=" kefir"> kefir</a>, <a href="https://publications.waset.org/abstracts/search?q=kefir%20supernatant" title=" kefir supernatant"> kefir supernatant</a>, <a href="https://publications.waset.org/abstracts/search?q=raw%20milk" title=" raw milk "> raw milk </a> </p> <a href="https://publications.waset.org/abstracts/24330/antioxidant-activity-of-the-algerian-traditional-kefir-supernatant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24330.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">506</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">659</span> The Impact of Milk Transport on Its Quality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Urszula%20Malaga-Tobo%C5%82a">Urszula Malaga-Toboła</a>, <a href="https://publications.waset.org/abstracts/search?q=Marek%20Guga%C5%82a"> Marek Gugała</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafa%C5%82%20Kornas"> Rafał Kornas</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Rusinek"> Robert Rusinek</a>, <a href="https://publications.waset.org/abstracts/search?q=Marek%20Gancarz"> Marek Gancarz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work focused on presenting the elements that determine the quality of fresh milk in the context of the quality of its transport. The quality of the raw material depends on the quality of transport. Milk transport involves many activities in which, apart from the temperature and sterility of the means of transport, it is important not to expose the raw material to shocks. Recently, there have been changes in the milk supply chain, thus affecting the logistics processes between its links. Based on the conducted research and analyses, it was found that the condition of the road surface on which milk is transported affects its quality. For the T1 milk transport route- gravel roads of very poor and poor quality, the lowest number of bacteria and the highest number of somatic cells, fat content, and temperature of the transported milk were obtained. A well-organized integrated transport system is a real need for most companies today. The analysis showed significant differences in the quality of milk delivered to the dairy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fresh%20milk" title="fresh milk">fresh milk</a>, <a href="https://publications.waset.org/abstracts/search?q=transport" title=" transport"> transport</a>, <a href="https://publications.waset.org/abstracts/search?q=milk%20quality" title=" milk quality"> milk quality</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy" title=" dairy"> dairy</a> </p> <a href="https://publications.waset.org/abstracts/181444/the-impact-of-milk-transport-on-its-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181444.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">81</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">658</span> The Pomade for Treatment of Bovine Papilomavirus-Induced Warts in Teats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Kale">Mehmet Kale</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramazan%20Sencan"> Ramazan Sencan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sibel%20Yavru"> Sibel Yavru</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20%20Ak"> Ahmet Ak</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuri%20Mamak"> Nuri Mamak</a>, <a href="https://publications.waset.org/abstracts/search?q=Sibel%20Has%C4%B1rc%C4%B1oglu"> Sibel Hasırcıoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesih%20Kocamuftuoglu"> Mesih Kocamuftuoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yakup%20Y%C4%B1ld%C4%B1r%C4%B1m"> Yakup Yıldırım</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasbi%20Sait%20Salt%C4%B1k"> Hasbi Sait Saltık</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bovine Papilloma Virus (BPV)-induced warts can cause mastitis, teat blindness, reduction of milk yield, udder deformities, and a difficulty in getting the teats into the milking machine. Especially, surgical operations cannot be performed in BPV-induced teat warts because of the increased sensitivity of the breast region and small-sized papillomas. Thus, there is a need to find new topical treatment methods. We have developed a pomade for treatment of BPV in cattle. The pomade is consists of lanoline, snakeskin (two special kind of snake), alcohol, vaseline, and ether. Firstly, we determined 46 cattle with teat warts. In the study, BPV antigen was detected in 28 cattle blood samples (61%) by ELISA. The pomade was applied to all BPV infected animals. The regression and recovery of warts were 100% in all animals. We advised using the pomade for treatment of BPV-induced warts in teats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bovine%20papilloma%20virus" title="bovine papilloma virus">bovine papilloma virus</a>, <a href="https://publications.waset.org/abstracts/search?q=pomade" title=" pomade"> pomade</a>, <a href="https://publications.waset.org/abstracts/search?q=teat" title=" teat"> teat</a>, <a href="https://publications.waset.org/abstracts/search?q=udder" title=" udder"> udder</a> </p> <a href="https://publications.waset.org/abstracts/87465/the-pomade-for-treatment-of-bovine-papilomavirus-induced-warts-in-teats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87465.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">225</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">657</span> Improving Physicochemical Properties of Milk Powder and Lactose-Free Milk Powder with the Prebiotic Carrier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chanunya%20Fahwan">Chanunya Fahwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Supat%20Chaiyakul"> Supat Chaiyakul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A lactose-free diet is imperative for those with lactose intolerance and experiencing milk intolerance.

Pectin was extracted in hot HCl solution. Thermo-precipitation was carried out to obtain the whey proteins while the gelatin was extracted by hydrolysis of the collagen from bovine ossein. The fermented milk was prepared by varying the concentration of the incorporated additives. The measures and controls carried performed periodically on fermented milk experimental tests were carried out: pH, acidity, viscosity, the enumeration of Streptococcus thermophilus, cohesiveness, adhesiveness, taste, aftertaste, whey exudation, and odor. It appears that the acidity, viscosity, and number of Streptococcus thermophilus increased with increasing concentration of additive added in the experimental tests. Indeed, it seems clear that the quality of fermented milk and storability is more improved than the incorporation rate is high. The products showed a better test and a firmer texture limiting the whey exudation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fermented%20milk" title="fermented milk">fermented milk</a>, <a href="https://publications.waset.org/abstracts/search?q=pectin" title=" pectin"> pectin</a>, <a href="https://publications.waset.org/abstracts/search?q=gelatin" title=" gelatin"> gelatin</a>, <a href="https://publications.waset.org/abstracts/search?q=whey%20proteins" title=" whey proteins"> whey proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20properties" title=" functional properties"> functional properties</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation" title=" conservation"> conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=valorization" title=" valorization"> valorization</a> </p> <a href="https://publications.waset.org/abstracts/112954/effects-of-certain-natural-food-additives-pectin-gelatin-and-whey-proteins-on-the-qualities-of-fermented-milk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112954.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">655</span> Static Light Scattering Method for the Analysis of Raw Cow's Milk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Villa-Cruz">V.

This method is based on the analysis of the dispersion of light laser produced by a set of particles in solution. Based on the above, raw milk, which contains particles of fat globules, with a diameter of 2000 nm and particles of micelles of protein with 300 nm in diameter were analyzed. For this, dilutions of commercial milk were made (1.0%, 2.0% and 3.3%) to obtain a pattern of laser light scattering and also made measurements of raw cow's milk. Readings were taken in a sweep initial angle 10° to 170°, results were analyzed with the program OriginPro 7. The SLS method gives us an estimate of the percentage of fat content in milk samples. It can be concluded that the SLS method, is a quick method of analysis to detect adulteration in raw cow's milk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=light%20scattering" title="light scattering">light scattering</a>, <a href="https://publications.waset.org/abstracts/search?q=milk%20analysis" title=" milk analysis"> milk analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=adulteration%20in%20milk" title=" adulteration in milk"> adulteration in milk</a>, <a href="https://publications.waset.org/abstracts/search?q=micelles" title=" micelles"> micelles</a>, <a href="https://publications.waset.org/abstracts/search?q=OriginPro" title=" OriginPro "> OriginPro </a> </p> <a href="https://publications.waset.org/abstracts/28216/static-light-scattering-method-for-the-analysis-of-raw-cows-milk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28216.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">375</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">654</span> Possibilities of Using Chia Seeds in Fermented Beverages Made from Mare’s and Cow’s Milk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nancy%20Mahmoud">Nancy Mahmoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Teichert"> Joanna Teichert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, fermented milk containing probiotic microorganisms is fundamental to human health. The changes in the properties of fermented milk during storage influence the quality and consumer acceptability. This study aimed to evaluate the effect of 1.5 % of chia seeds on the chemical, physical and sensory properties of fermented cow’s and mare’s milk for two weeks at 4°C. The results showed that the pH of cow’s milk drops significantly at the 2nd hour, but mare's milk drops significantly at the 6th hour. The acidity of both types of milk increased as the storage time progressed. Adding chia seeds increased firmness significantly and improved color and consistency. A decrease in brightness (L*), an increase in redness (a*), and yellowness (b*) during storage were observed. Our study showed that the chia seeds have more effect on reducing the brightness of fermented mare milk than fermented cow milk. Analysis of taste and smell parameters showed that after adding chia seeds, the scores changed and became much higher. The sour taste of fermented milk had reduced this positively affected the acceptance of the product. Chia seeds induced beneficial effects on sensory outcomes and enhanced physiochemical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mare%20milk" title="mare milk">mare milk</a>, <a href="https://publications.waset.org/abstracts/search?q=cow%20milk" title=" cow milk"> cow milk</a>, <a href="https://publications.waset.org/abstracts/search?q=feremnted%20milk" title=" feremnted milk"> feremnted milk</a>, <a href="https://publications.waset.org/abstracts/search?q=kefir" title=" kefir"> kefir</a>, <a href="https://publications.waset.org/abstracts/search?q=koumiss" title=" koumiss"> koumiss</a> </p> <a href="https://publications.waset.org/abstracts/163677/possibilities-of-using-chia-seeds-in-fermented-beverages-made-from-mares-and-cows-milk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163677.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">98</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">653</span> Electrochemical Bioassay for Haptoglobin Quantification: Application in Bovine Mastitis Diagnosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soledad%20Carinelli">Soledad Carinelli</a>, <a href="https://publications.waset.org/abstracts/search?q=I%C3%B1igo%20Fern%C3%A1ndez"> Iñigo Fernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luis%20Gonz%C3%A1lez-Mora"> José Luis González-Mora</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20A.%20Salazar-Carballo"> Pedro A. Salazar-Carballo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mastitis is the most relevant inflammatory disease in cattle, affecting the animal health and causing important economic losses on dairy farms. This disease takes place in the mammary gland or udder when some opportunistic microorganisms, such as Staphylococcus aureus, Streptococcus agalactiae, Corynebacterium bovis, etc., invade the teat canal. According to the severity of the inflammation, mastitis can be classified as sub-clinical, clinical and chronic. Standard methods for mastitis detection include counts of somatic cells, cell culture, electrical conductivity of the milk, and California test (evaluation of “gel-like” matrix consistency after cell lysed with detergents). However, these assays present some limitations for accurate detection of subclinical mastitis. Currently, haptoglobin, an acute phase protein, has been proposed as novel and effective biomarker for mastitis detection. In this work, an electrochemical biosensor based on polydopamine-modified magnetic nanoparticles (MNPs@pDA) for haptoglobin detection is reported. Thus, MNPs@pDA has been synthesized by our group and functionalized with hemoglobin due to its high affinity to haptoglobin protein. The protein was labeled with specific antibodies modified with alkaline phosphatase enzyme for its electrochemical detection using an electroactive substrate (1-naphthyl phosphate) by differential pulse voltammetry. After the optimization of assay parameters, the haptoglobin determination was evaluated in milk. The strategy presented in this work shows a wide range of detection, achieving a limit of detection of 43 ng/mL. The accuracy of the strategy was determined by recovery assays, being of 84 and 94.5% for two Hp levels around the cut off value. Milk real samples were tested and the prediction capacity of the electrochemical biosensor was compared with a Haptoglobin commercial ELISA kit. The performance of the assay has demonstrated this strategy is an excellent and real alternative as screen method for sub-clinical bovine mastitis detection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bovine%20mastitis" title="bovine mastitis">bovine mastitis</a>, <a href="https://publications.waset.org/abstracts/search?q=haptoglobin" title=" haptoglobin"> haptoglobin</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemistry" title=" electrochemistry"> electrochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20nanoparticles" title=" magnetic nanoparticles"> magnetic nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=polydopamine" title=" polydopamine"> polydopamine</a> </p> <a href="https://publications.waset.org/abstracts/148029/electrochemical-bioassay-for-haptoglobin-quantification-application-in-bovine-mastitis-diagnosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148029.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">173</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">652</span> Associations between Polymorphism of Growth Hormone Gene on Milk Production, Fat and Protein Content in Friesian Holstein Cattle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tety%20Hartatik">Tety Hartatik</a>, <a href="https://publications.waset.org/abstracts/search?q=Dian%20Kurniawati"> Dian Kurniawati</a>, <a href="https://publications.waset.org/abstracts/search?q=Adiarto"> Adiarto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the research was to determine the associations between polymorphism of the bovine growth hormone (GH) gene (Leu/Val, L/V) and milk production of Friesian Holstein Cattle.

Forty-five milk and milk product (yoghurt) samples were digested and analysed for selected metals using Atomic Absorption Spectrophotometric method. Health risk assessment was evaluated for hazard quotient (HQ), hazard index (HI), and cancer risk (CR). Data were subjected to descriptive and inferential statistics. The concentrations of Zn, which ranged from 3.24±0.59 to 4.35±0.59 mg/kg, were the highest in the samples. Cr and Cd were measured below the detection limit of the analytical instrument, while the Pb level was higher than the Codex Alimentarius Commission value of 0.02 mg/kg, indicating unsafe for consumption. However, the HQ of Pb and other metals in milk and milk product samples was less than 1.0, thereby establishing no adverse health effects for Pb and other metals.

Indeed it has been used as a treatment for several diseases such as tuberculosis, dropsy, asthma, jaundice and leishmaniasis in India, Sudan and some parts of Russia. A wealth of references is available in literature for the composition of milk from different diary animals such as cows, goats and sheep. Camel milk instead has not been extensively studied, despite its nutritional value. In this study commercial cow and camel milk samples, bought from the local market, were analyzed by 1D 1H-NMR and multivariate statistics in order to identify the different composition of the low-molecular-weight compounds in the milk mixtures. The samples were analyzed in their native conditions without any pre-treatment. Our preliminary study shows that the two different types of milk samples differ in the content of metabolites such as orotate, fats and more. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=camel" title="camel">camel</a>, <a href="https://publications.waset.org/abstracts/search?q=cow" title=" cow"> cow</a>, <a href="https://publications.waset.org/abstracts/search?q=milk" title=" milk"> milk</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuclear%20Magnetic%20Resonance%20%28NMR%29" title=" Nuclear Magnetic Resonance (NMR)"> Nuclear Magnetic Resonance (NMR)</a> </p> <a href="https://publications.waset.org/abstracts/22711/analysis-of-commercial-cow-and-camel-milk-by-nuclear-magnetic-resonance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22711.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">564</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">649</span> Evaluation of Antagonistic and Aggregation Property of Probiotic Lactic Acid Bacteria Isolated from Bovine Milk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alazar%20Nebyou">Alazar Nebyou</a>, <a href="https://publications.waset.org/abstracts/search?q=Sujata%20Pandit"> Sujata Pandit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lactic acid bacteria (LAB) are essential ingredients in probiotic foods, intestinal microflora, and dairy products that are capable of coping up with harsh gastrointestinal tract conditions and are available in a variety of environments. The objective of this study is to evaluate the probiotic property of LAB isolated from bovine milk. Milk samples were collected from local dairy farms. Samples were obtained using sterile test tubes and transported to a laboratory in the icebox for further biochemical characterization. Preliminary physiological and biochemical identification of LAB isolates was conducted by growing on MRS agar after ten-fold serial dilution. Seven of the best isolates were selected for the evaluation of the probiotic property. The LAB isolates were checked for resistance to antibiotics and their antimicrobial activity by disc diffusion assay and agar well diffusion assay respectively. Bile salt hydrolase activity of isolates was studied by growing isolates in a BSH medium with bile salt. Cell surface property of isolates was assayed by studying their autoaggregation and coaggregation percentage with S. aerues. All isolates were found BSH positive. In addition, BCM2 and BGM1 were susceptible to all antibiotic disks except BBM1 which was resistant to all antibiotic disks. BCM1 and BGM1 had the highest autoaggregation and coaggregation potential respectively. Since all LAB isolates showed gastrointestinal tolerance and good cell surface property they could be considered as good potential probiotic candidates for treatment and probiotic starter culture preparation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=probiotic" title="probiotic">probiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=aggregation" title=" aggregation"> aggregation</a>, <a href="https://publications.waset.org/abstracts/search?q=lactic%20acid%20bacteria" title=" lactic acid bacteria"> lactic acid bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a> </p> <a href="https://publications.waset.org/abstracts/136936/evaluation-of-antagonistic-and-aggregation-property-of-probiotic-lactic-acid-bacteria-isolated-from-bovine-milk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136936.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">214</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">648</span> Assessment of Procurement-Demand of Milk Plant Using Quality Control Tools: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jagdeep%20Singh">Jagdeep Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Prem%20Singh"> Prem Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Milk is considered as an essential and complete food. The present study was conducted at Milk Plant Mohali especially in reference to the procurement section where the cash inflow was maximum, with the objective to achieve higher productivity and reduce wastage of milk. In milk plant it was observed that during the month of Jan-2014 to March-2014 the average procurement of milk was Rs. 4, 19, 361 liter per month and cost of procurement of milk is Rs 35/- per liter. The total cost of procurement thereby equal to Rs. 1crore 46 lakh per month, but there was mismatch in procurement-production of milk, which leads to an average loss of Rs. 12, 94, 405 per month. To solve the procurement-production problem Quality Control Tools like brainstorming, Flow Chart, Cause effect diagram and Pareto analysis are applied wherever applicable. With the successful implementation of Quality Control tools an average saving of Rs. 4, 59, 445 per month is done. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=milk" title="milk">milk</a>, <a href="https://publications.waset.org/abstracts/search?q=procurement-demand" title=" procurement-demand"> procurement-demand</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20control%20tools" title=" quality control tools"> quality control tools</a>, <a href="https://publications.waset.org/abstracts/search?q=" title=""></a> </p> <a href="https://publications.waset.org/abstracts/28242/assessment-of-procurement-demand-of-milk-plant-using-quality-control-tools-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28242.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">532</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">647</span> Effect of Goat Milk Kefir and Soy Milk Kefir on IL-6 in Diabetes Mellitus Wistar Mice Models Induced by Streptozotocin and Nicotinamide</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agatha%20Swasti%20Ayuning%20Tyas">Agatha Swasti Ayuning Tyas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hyperglycemia in Diabetes Mellitus (DM) is an important factor in cellular and vascular damage, which is caused by activation of C Protein Kinase, polyol and hexosamine track, and production of Advanced Glycation End-Products (AGE). Those mentioned before causes the accumulation of Reactive Oxygen Species (ROS). Oxidative stress increases the expression of proinflammatory factors IL-6 as one of many signs of endothelial disfunction. Genistein in soy milk has a high immunomodulator potential. Goat milk contains amino acids which have antioxidative potential. Fermented kefir has an anti-inflammatory activity which believed will also contribute in potentiating goat milk and soy milk. This study is a quasi-experimental posttest-only research to 30 Wistar mice. This study compared the levels of IL-6 between healthy Wistar mice group (G1) and 4 DM Wistar mice with intervention and grouped as follows: mice without treatment (G2), mice treated with 100% goat milk kefir (G3), mice treated with combination of 50% goat milk kefir and 50% soy milk kefir (G4), and mice treated with 100% soy milk kefir (G5). DM animal models were induced with Streptozotocin & Nicotinamide to achieve hyperglycemic condition. Goat milk kefir and soy milk kefir are given at a dose of 2 mL/kg body weight/day for four weeks to intervention groups. Blood glucose was analyzed by the GOD-POD principle. IL-6 was analyzed by enzyme-linked sandwich ELISA. The level of IL-6 in DM untreated control group (G2) showed a significant difference from the group treated with the combination of 50% goat milk kefir and 50% soy milk kefir (G3) (p=0,006) and the group treated with 100% soy milk kefir (G5) (p=0,009). Whereas the difference of IL-6 in group treated with 100% goat milk kefir (G3) was not significant (p=0,131). There is also synergism between glucose level and IL-6 in intervention groups treated with combination of 50% goat milk kefir and 50% soy milk kefir (G3) and the group treated with 100% soy milk kefir (G5). Combination of 50 % goat milk kefir and 50% soy milk kefir and administration of 100% soy milk kefir alone can control the level of IL-6 remained low in DM Wistar mice induced with streptozocin and nicotinamide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title="diabetes mellitus">diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=goat%20milk%20kefir" title=" goat milk kefir"> goat milk kefir</a>, <a href="https://publications.waset.org/abstracts/search?q=soy%20milk%20kefir" title=" soy milk kefir"> soy milk kefir</a>, <a href="https://publications.waset.org/abstracts/search?q=interleukin%206" title=" interleukin 6"> interleukin 6</a> </p> <a href="https://publications.waset.org/abstracts/65540/effect-of-goat-milk-kefir-and-soy-milk-kefir-on-il-6-in-diabetes-mellitus-wistar-mice-models-induced-by-streptozotocin-and-nicotinamide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65540.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">285</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">646</span> Differential Antibrucella Activity of Bovine and Murine Macrophages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raheela%20Akhtar">Raheela Akhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Zafar%20Iqbal%20Chaudhary"> Zafar Iqbal Chaudhary</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongqun%20Oliver%20He"> Yongqun Oliver He</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Younus"> Muhammad Younus</a>, <a href="https://publications.waset.org/abstracts/search?q=Aftab%20Ahmad%20Anjum"> Aftab Ahmad Anjum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brucella abortus is an intracellular pathogen affecting macrophages. Macrophages release some components such as lysozymes (LZ), reactive oxygen species (ROS) and reactive nitrite intermediates (RNI) which are important tools against intracellular survival of Brucella. The antibrucella activity of bovine and murine macrophages was compared following stimulation with Brucella abortus lipopolysaccharides. Our results revealed that murine macrophages were ten times more potent to produce antibrucella components than bovine macrophages. The differential production of these components explained the differential Brucella killing ability of these species that was measured in terms of intramacrophagic survival of Brucella in murine and bovine macrophages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bovine%20macrophages" title="bovine macrophages">bovine macrophages</a>,
