Abstract
THE INFLUENCE OF SIRES ON MILK YIELDS AND ITS QUALITY IN STALL HOUSING OF COW
Highlights
The results of the dispersion analysis of variance indicate that the strength of sires impact on milk yields – 2.11%, fat content – 4,21%, protein content – 8,2%, somatic cell count – 1,14% (P < 0,001)
It was found that the impact of this factor on the milk physicochemical properties and the number of mastiticases of their daughters is greater than the factor "line"
Кількість хворих на мастит корів повторює тенденцію із середнім вмістом соматичних клітин у молоці корів різних ліній
