Effect of some factors on yield and composition of milk in 5 successive lactations of Polish Black-and-White Lowland cows in Olsztyn province. I. Effect of age at first calving



Effect of some factors on yield and composition of milk in 5 successive lactations of Polish Black-and-White Lowland cows in Olsztyn province. I. Effect of age at first calving



Roczniki Nauk Rolniczych, B 95(1): 9-22



Records of 2611 consecutive lactations (1st-5th) of 653 Polish Black-and-White Lowland cows from 20 high-quality breeding herds in Olsztyn province between 1962-1969 were examined from the viewpoint of effect of age at 1st calving (classified into 8 categories between 21 and more than or equal to 42 months) on milk, milk fat and milk protein yields and fat and protein %.
