Abstract. The article talks about the formation of cows with different genotypes. Group I included cows obtained by crossing Simmental cattle with Red-Motley Holstein breed, with 20% Holstein and 80% Simmental blood. In groups II and III, purebred Flegfih Simmental-Red-Motley cows were selected. In this experiment, attention is primarily focused on improving the breeding and productive qualities of improving breeds, adapting to various natural and climatic conditions, studying the problems of genotype-environment relationships, and manifesting the genetic productive potential.
