BACKGROUND Q fever is a zoonotic disease caused by the bacterium Coxiella burnetii. Prevalence data in ruminant species are important to support risk assessments regarding public and animal health. The aim was to investigate the presence of or exposure to C. burnetii in cattle, sheep, goats and moose, and to compare two enzyme-linked immunosorbent assays (ELISAs). National surveys of antibodies...

Alkaline phosphatase is used as the main marker in evaluation of successful milk pasteurization, although there concern about whether this method appropriate for non-cow milk. We systematically reviewed articles related to ALP and dairy products. From a total 183 studies retrieved, 31 were included review. Our study shows that most research focused on goat sheep milk, while other species are ra...

The effects of sheep alpha s1-casein CC, CD and DD genotypes on milk composition and cheese yield were studied. Processed bulk milk was collected from three groups of 15 ewes, carrying alpha s1-casein CC, CD and DD genotypes. CC milk was higher in casein content than CD or DD milk (+3.5 and +8.6% respectively), and had a higher protein: fat ratio and a smaller casein micelle diameter. In additi...

Market failures are the main cause of poor acknowledgement of the true impact of functional sheep traits on the management and economic performance of farms, which results in their omission from the breeding goal or the estimation of non-representative economic weights in the breeding goal. Consequently, stated-preference non-market valuation techniques, which recently emerged to mitigate these...

BACKGROUND The risk of scrapie infection increases with increased duration and proximity of contact between sheep at lambing. Scrapie infectivity has not been detected in milk but cellular prion protein, the precursor of disease-associated prion protein PrPd, has been found in milk from ruminants. To determine whether milk is able to transmit scrapie, 18 lambs with a prion protein genotype asso...

Cryptosporidium is a protozoan parasite that infects epithelial cells of the intestine in a wide variety of vertebrates. During the last decade, cryptosporidiosis has emerged as a cause of diarrhea in man. Most of the' patients have AIDS, and have had contact with infected animals. In this study ' 510 samples were collected from sheep and examined for detection of this parasite. The result...

Animal species identification of milk and dairy products has received increasing attention concerning food composition, traceability, allergic pathologies and accurate consumer information. Here we sought to develop an easy to use and robust method for species identification in cheese with emphasis on an authenticity control of PDO Feta cheese products. We used specific mitochondrial DNA region...

The triglyceride compositions of the milk fats of man, dog, guinea pig, cow, sheep, goat, and horse were compared by gas-liquid chromatography of the intact triglycerides and of the butyl esters of the component fatty acids. The milk fats of man, dog, and guinea pig, which were largely made up of long-chain fatty acids, showed a common pattern with major contributions made by the glycerides wit...

■ 42. Amend § 558.195 as follows: ■ a. In the table in paragraph (e)(1)(i), in the ‘‘Limitations’’ column, remove ‘‘Do not feed to laying chickens.’’ and in its place add ‘‘Do not feed to laying hens producing eggs for human consumption.’’; ■ b. In the table in paragraph (e)(2)(i), in the ‘‘Limitations’’ column, remove ‘‘Do not feed to cows producing milk for food.’’ and in its place add ‘‘Do n...

Abstract Background Sheep milk is a nutritional and health-promoting food source for humans. The DEATH superfamily conserved protein family, some of its members are closely related to lactation. Systematic studies the important further understanding functions in mammary gland during lactation; however, there currently lacking. Results Herein, 74 were identified sheep, phylogenetic analyses indi...
