Abstract
Analysis of these results from PCR-RFLP of Kalmyk breed bulls at the GH and Tg5 locus in breeding breeders of the Republic of Kalmykia determined the following: for the GH gene, out of 86 samples, 44% were carriers of the homozygous VV genotype, 26% of animals became carriers of the heterozygous LV genotype, and with the homozygous genotype LL they numbered 30%. For the Tg5 gene, out of 80 samples, 31% are carriers of the homozygous TT genotype, 48% of animals were carriers of the heterozygous TG genotype, 21% of animals were carriers of the homozygous GG genotype. The percentage of desirable genotypes associated with economically valuable productivity indicators — VV and TT, do not differ significantly (44% and 31%, respectively) among themselves and are at an average level. This can be explained by targeted selection and breeding work in the studied herds.
