Technologies for genetic labeling of economically useful traits using polymorphic variants of genes that control the rate of growth and development of animals make it possible to assess the genetic potential of an animal immediately after birth, which significantly reduces time and financial costs. This study aimed to identify paired combinations of the genes growth hormone, growth hormone receptor, and insulin-like growth factor-1 associated with meat productivity in related breeds of cattle meat direction: Hereford, Kazakh white-headed, Aberdeen Angus, Auliekol. The materials for the study were blood and hair follicles samples of animals born in 2015, aged 18 and 24 months. The animals were selected from farms in northern Kazakhstan with equal feeding and housing conditions. The PCR-RFLP method was used to determine the genotypes of animals. According to the results of this study, the associations of phenotypes with the genotypes of the bGH, bGHR, and bIGF-1 genes in the studied cattle breeds were revealed.
