Systematic approach in optimization of breeding programs and search for optimal crossing options in domestic dairy breed populations is a poorly studied direction. Theoretical substantiation of the effectiveness of crossbreeding in domestic dairy breeds to increase the level of reproductive capacity, duration of economic use of cows, survival of calves, qualitative signs of milk productivity (fat, protein content) - measures that do not cause doubt in their relevance. The purpose of the work is to determine the effectiveness of the selection of breeding animals during purebred breeding and crossbreeding in the process of improving productive traits of dairy cattle.
