The objective of the study was to investigate the influence of SNP CAST 283 on the development of meat qualities in young cattle of Hereford and Limousin breeds in postnatal ontogenesis. The objectives of the study included: genotyping of young cattle by SNP CAST C283T, determination of genotypic structure, allelic state, level of genetic diversity and equilibrium of the studied herds of Hereford and Limousin cattle, study of live weight dynamics in postnatal ontogenesis, post-slaughter carcass evaluation, chemical composition of beef and structural and mechanical properties of meat obtained from steers of different genotypes. The results of genotyping of bulls of Hereford and Limousin breeds by SNP CAST C283T, testify to high frequency of occurrence in both herds of genotype CASTSS and low desirable genotype CASTTT (7.5% in Herefords and 4.18% in Limousins), a low frequency of the allele CASTT (0.29 and 0.26) was noted. In our studies, no significant relationship of the studied SNP CAST C283T with weight growth, post-slaughter parameters and chemical composition of meat of steers of different genotypes was found. There was a significant association of the studied polymorphism with lower cutting force of the longest muscle of the back in steers with the genotype CASTTT at the end of the first day and on the third day of the experiment, which allows us to recommend this polymorphism as a marker of "tenderness" of beef in selection work with Hereford and Limousin cattle.
