METHOD FOR SELECTION OF NEAT CATTLE BY MILK PRODUCTIVITY Russian patent published in 2010 - IPC A01K67/02 

FIELD: agriculture.

SUBSTANCE: invention relates to selection and genetics of neat cattle. Method consists in the fact that immune-genetic analysis of 20 days-old animals' blood groups is carried out, when erythrocyte antigens are identified - markers of milk productivity of seven indicators of inherited abilities: antigens-markers of enhanced milk yields - Q, C₂, L', L; antigens-markers of enhanced milk yields and milk fat content - C₁, R₂; antigens-markers of enhanced milk yields, reduced fat content of milk - E; antigens-markers of reduced milk yields, high fat content of milk - B₂, G₂, O', P', X₂, H", U"; antigens-markers of reduced milk yields - S₁; antigens-markers of enhanced fat content of milk - G₃, B', D', G', B", G", C' U, J; antigens-markers of reduced fat content of milk - A₂, P₂, U'. Bulls that improve milk productivity and heifers with inherited abilities of higher milk productivity are selected by availability of the following high-valued antigens-markers in animals genotype: milk yields - C₂, L', L, Q, milk fat - G₃, B', D', G', B", G", C', U, J, milk yields and milk fat - C₁, R_2.

EFFECT: method makes it possible to increase milk productivity and to improve profitability of milk production.
