GENOTYPED PRODUCING BOARS IN INDUSTRIAL PORK PRODUCTION

Abstract

Th paper dwells on results of researching the productivity of producing boars depending on the breed and the genetic profile according to DNA markers: the ryanodine receptor gene (RYR-1), the estrogen receptor gene (ESR), the meat performance gene (FABP). The data is presented confirming the expediency for genetic diagnostics in the reproducing part of the herd of both the boars and sows, which allow to objectively identify the alleles preferred for breeding. Selection of such animals as parental pairs will significantly increase the productivity of pigs. Besides the gene diagnostics, it is desirable to take into account the quantitative and qualitative indicators of semen product when including producing boars in the reproductive process, proceeding from real age of the animals and the breed, rather than being guided by exterior and weight indices. Preferred genotypes from the breeding point of view are BB (ESR gene), HHdd (H-FABR gene) and NN (RYR-1 gene). The AB, HhDd and Nn genotypes of the above mentioned genes are intermediate for selection, and AA, hhDD and nn are undesirable and unacceptable for further selection.
