FIELD: agriculture.
SUBSTANCE: method envisages selection of cows by blood group markers consisting in the following parental pairs alleles combinability used as immunogenetic markers: B2O1D"/G2Y2E'1Q'; G2Y2E'Q'/G2Y2E'1Q'; G2Y2E'1Q'/O2A'2J'1K'O'; O2A'2J'1K'O'/O4D'E'3F'2G'O'; O4D'E'3F'2G'O'/O4Y2A'1I"; O4Y2A'1I"/O4Y2A'1I" in accordance with the EAB blood group system. The level of homozygosity of cows with extended productive longevity term must not be in excess of 14%.
EFFECT: method allows to breed cows with extended productive longevity term.
