Оценка продуктивных качеств свиноматок по ДНК-маркерам

Abstract

The results of studies of the association of ESR and H-FABP genes with indicators of reproductive, fattening and meat qualities of sows of various genotypes are presented. An analysis of the association of polymorphic variants of sow marker genes showed that the ESRBB and ESRAB, H-FABPHH and H-FABPdd genotypes have a positive effect on a number of signs: multiple fertility, average daily gain, feed cost per gain 1 kg, fat thickness over 6-7 chest vertebrae and the mass of the rear third of the half-carcass. Breeding aimed at breeding animals with the preferred genes will improve reproductive, fattening and meat qualities in further breeding and breeding.
