Abstract

The first objective of this study was to examine milking-to-milking variations in milk fat, protein and SCC (somatic cell count). The second objective of this study was to examine variations of milk components (fat, protein and SCC) over a period of six months (April-September 2010) at Agricultural Research Development Station Simnic. A total of 128 milk samples (64 morning milking and 64 evening milking ones) from milk bulk tank commingled from 90±4 Holstein cows, were collected and analyzed for fat, protein and SCC. Data suggested that milking period effects milk fat, making the fat percentage lower in the morning compared with the evening milking period, effect which was not similar in protein content. Seasonal differences in milk fat and protein were also investigated. The season of year had influenced SCC, fat and protein: SCC increased, while fat and protein decreased. The period of the day when milking took place and the season influenced fat, protein and SCC, but the composition of milk, as well as its hygienic quality, fell within the aplicabile standards for raw milk.
