THE GENETIC POTENTIAL OF MILK PRODUCTION OF THE DAUGHTERS OF THE AMERICAN SHVITSY IN THE NORTH CAUCASUS

The article shows that between the experimental groups with age significant differences are not installed and those differences that were found were statistically not significant. Superiority in milk productivity of cows obtained from "freshening" the blood of the third lactation on the local shvitsy doesn't adversely affect their reproductive ability. This can be seen in terms of service period in cows at the third lactation, which is 52 days in cows of the experimental group and 63 days in cows of the control group.
