High somatic cell counts in milk caused by mastitis significantly influence the quality of milk and result in substantial annual economic loss. This study evaluated the beneficial effects of melatonin (MT) on milk somatic cell count (SCC) in cows. To examine the effects of melatonin on SCC, one hundred twenty cows were divided into four groups based on milk SCC. In each group, half of the cows ...

The influence of copper and zinc supplements on milk production performances and health indicators was tested in a 20week feeding trial, with 40 Holstein-Friesian lactating cows, divided in four groups (copper, zinc, copper-zinc and control). Correlations of the Cu and Zn plasma values with some animal performance criteria of health (body condition score and somatic cell counts) and production ...

Genetics can help prevent mastitis and reduce somatic cell count. The purpose of this article is to inform producers, veterinarians, extension personnel, artificial breeding personnel, and genetics specialists about the methods and usefulness of genetics to improve milk quality. The USDA Animal Improvement Programs Laboratory [AIPL] has published genetic evaluations for Somatic Cell Score (SCS)...

Although intensive research and prevention measures have been carried out for decades to control bovine mastitis, it continues to cause the biggest economic impact to the dairy industry worldwide. Severe economic losses, which are estimated to be approximately $200/cow/yr in the United States, are due to reduced milk production, discarded milk, replacement costs, extra labor, treatment, and vet...

lactoferrin (lf) is a bioactive protein present in all external secretions such as milk that plays important role in the innate host defense. therefore, the lf has a major role in bovine mammary gland defense during mastitis. in this study, 5’-flanking region of bovine lf gene containing three single nucleotide polymorphisms (snps) at positions −602 (t/g), −600 (a/g) and -586 (t/c) were screene...

The study was conducted in Addis Ababa town, central Ethiopia. To assess the general milk handling practice, determine physicochemical properties and evaluate the microbial quality of raw cow milk produced through the milk sheds found in the town. A cross sectional study was conducted in the study area and then purposively based on dairy potential three sub cities i.e., Akaki-Kality, Nifas Silk...

Abstract The goal of the present study was to verify quality refrigerated raw milk from dairy properties and also milk, pasteurized Ultra High Temperature (UHT) industries in Vale do Taquari Rio Grande Sul, Brazil. Physicochemical, microbiological composition analysis were carried out, as established by legislation, addition total thermotolerant coliforms psychrotrophic counts three types mesop...
