【 摘 要 】

The aim of this study was to investigate the phenotypic parameters in 101 dairy cows belonging to Romanian Black Spotted breed, from Petresti-Alba farm. For milk, fat and protein yield, cows were milked twice a day for a complete lactation of at least 305 days, from 2005 to 2007. Dairy cattle are the main milk supplier, the world production being over 650,000,000 MT/year. This production provides 35% of the total animal protein for the human consumption. Milk composition is of extreme importance to the consumer from a nutritional point of view. In the herd of dairy Romanian Black Spotted breed, from Petresti-Alba, the average milk yield was 4600.32±97.52 kg. The milk fat yield obtained per cow was 180.87±3.81 kg, while protein yield was 155.61±3.16 kg.
