Abstract

There was studied the influence of season of birth and calving on milk yield, fat content in milk and milk fat of Ukrainian Black-and-White dairy cattle in this work. It was established that animals with different season of birth and calving differed among themselves by the indicators of milk productivity. Cows born in autumn and winter had the highest yield and quantity of milk fat. Abovementioned seasons of calving cows marked the best indicators of milk production. However, the correlation coefficients between the studied parameters and the share of influence of birth season and calving season on milk yield, fat content in milk and milk fat amount was insignificant.
