FIELD: agriculture.
SUBSTANCE: method involves blood research for 20-days old animals to detect the presence of erythrocytic marker antigens of two types: high growth energy antigens B2, G2, I', O', Q', V, H", and low growth energy antigens Q, T1, S1. Animals with high growth energy markers present in genotype or prevailing over low growth energy markers are selected.
EFFECT: improved posterity meat productivity by 5,8-9,4%.
