This research investigated the effect of lameness, measured by locomotion score (LS) on the somatic cell count (SCC) of UK dairy cows. The data set consisted of 11,141 records of SCC and LS collected monthly on 12 occasions from 1,397 cows kept on 7 farms. The data were analyzed to account for the correlation of repeated measures of SCC within cow. Results were controlled for farm of origin, st...

Interactions between inflammatory cytokines and plasminogen (Pg) activation system on immune cells are yet to be established. In previous studies we reported a somatic cell-associated elevation of proteolytic activity in mammary secretion of drying-off goats and cows. The purposes of the present study were to examine the role of TNF-alpha in polymorphonuclear neutrophil (PMN)-associated Pg acti...

Daily milk, fat and protein yield and amount of somatic cells in cow milk are very important factors that influence milk performance traits. An association between polymorphisms in the kappa casein (CSN3) gene and milk production, composition and technical properties has been previously reported; however, this type of information is not available for the bovine β-carotene oxygenase 2 (BCO2) gen...

historically, biomarkers have been used in two major ways to maintain and improve better health status: first, for diagnostic purposes, and second, as specific targets to treat various diseases.   a new era in treatment and even cure for the some diseases using reprograming of somatic cells is about to be born. in this approach, scientists are successfully taking human skin cells (previously co...

The cholesterol content in cow milk is influenced by both genetic and environmental factors. Despite the fact that the main part of cholesterol contained in milk is synthesised endogenously, via process independent of the offered diet type, the chemical composition of feed (especially fat) affects the content of this sterol in cow milk (Precht, 2001). The content of cholesterol in cow milk is r...

Lactational means of somatic cell score from sample days of primiparous DHI cows were analyzed to compare dairy records processing centers for data properties, to examine effects of age at calving and month of calving on somatic cell score, and to calculate preliminary PTA of sires for somatic cell scores. Five processing centers contributed data but differed substantially with respect to avail...

in the past decade, a global demand for products from organic agriculture has increased rapidly. milk quality is of major interest for all parties. therefore, the objective of this study was to compare cow performance and product quality in conventional and organic system. twenty holstein dairy cows were allotted to one of 2 diet groups, which including: a conventional diet (con), and an organi...
