THE PRODUCTIVITY OF PIGS of maternal breeds by a complex of molecular genetic markers determining reproductive traits

Abstract

The analysis of quantitative traits of maternal breeds of pigs productiveness by complex of molecular and genetic markers determining reproduction traits was carried out. It was determined that the complex of molecular and genetic markers (ESR, RYR1, EPOR, ECR F18), determining reproductive performance, has specific effect on quantitative traits of maternal breeds of pigs performance. Thus, the use of these markers in breeding maternal breeds of sows improves their performance traits: multiple pregnancy - by 2.2-12.7 %, and the safety of piglets at weaning - by 1.3-19.9 p.p. Genetic profiles of maternal breeds of pigs were developed, which reflect the frequency of alleles of molecular and genetic markers for performance traits that allows to predict their quantitative traits of performance with high accuracy, as well as criteria for boars ranking, the use of which allows to objectively evaluate the producer and use it efficiently for selection of parental pairs.
