The current study investigated the impact of growth hormone (GH) and polymorphism of calpain genes (CAPN1) on the changes in live weight and qualitative and quantitative indicators of meat productivity of young Kazakh White-headed cattle. CAPN1 polymorphism is represented by two alleles, C and G, with a frequency of 0.12 and 0.88, three genotypes, CC, CG, GG, with a frequency of 0.06, 0.81, and 0.13, respectively. GH polymorphism - V and L alleles, with a frequency of 0.40 and 0.60, and VV, LV, and LL genotypes with a frequency of 0.31, 0.51, and 0.18, respectively. The CAPN1C and GHV alleles are preferred for improving the quantity and quality of meat productivity of the Kazakh white-headed cattle. Animals with the CAPN1CC and GHVV genotypes had a 6.9% higher body weight at 12 months of age (P
