Summary: The research urgency is caused by obtaining an objective prognosis of productivity on the basis of true genetic potential of animals at selection of pigs on increase of productive qualities. In this regard this article is aimed at identifying the productivity of breeding boars depending on the breed and the genetic profile on the DNA markers: the ryanodine receptor gene (RYR-1), the estrogen receptor gene (ESR), the meat production gene (FABP). The leading method to an estimation of this problem is the breeding value evaluation of animal based on DNA markers, which allows us to obtain the information on the genotype of the animal and its productive qualities. The article presents data confirming the expediency for genetic diagnosis in the reproducing part of the herd both boars and sows, which allow us objectively to identify the alleles preferred for breeding. Selection of such animals as parental pairs will significantly increase the productivity of pigs. Besides gene diagnosis, it is desirable at inclusion of the breeding boars in the reproductive process to take into account the quantitative and qualitative indicators of sperm production proceeding from real age of the animals and their breed, rather than being guided by exterior and weight indices. Preferred from the point of view of breeding are such genotypes as BB (ESR gene), HHdd (H-FABR gene) and NN (RYR-1 gene). The AB, HhDd and Nn genotypes of above-mentioned genes are intermediate for selection, and AA, hhDD and nn are undesirable and unacceptable for further selection. The materials of the article are of the of practical value for scientific workers, breeders and specialists in pig farms, since traditional methods of breeding largely supplemented by genetic markers, allow the evaluation, selection and choice of individuals with the desired genotypes to be more efficient.
Key words: pigs, productivity, DNA diagnosis, genotype, genetic markers
