GENETIC PROFILES OF BELARUSIAN LARGE WHITE PIGS AT BREEDING ENTERPRISES OF THE REPUBLIC OF BELARUS
Abstract
Presently, the number of pigs of the Belarusian Large White breed has noticeably decreased. To solve the issue of preservation and further development of this breed at the breeding enterprises of the republic, it is necessary to use more advanced methods of selection and genetic evaluation of pigs, that is according to the true genetic potential. The article presents the materials of scientific work, the purpose of which was to build genetic profiles of pigs of the Belarusian Large White breed at breeding enterprises of the Republic of Belarus. Studies have shown that animals of the Belarusian Large White breed have a fairly high frequency of preferred alleles for the RYR1 gene (the animals are stress-resistant) and the H-FABP gene (they have relatively high levels of intramuscular fat content), an average frequency for multiple pregnancy (ESR gene) and low in terms of fattening traits (IGF-2 gene). The construction of genetic profiles will make it possible to develop programs for selection of parental pairs taking into account the genotypes and alleles of marker genes of performance traits.
