In the conditions of farms of the Republic of Belarus there was determined the genetic structure of the Landrace breed of the French selection for genes RYR1, ESR, H-FABP , as well as there was examined the association of polymorphism marker genes with key indicators of animal productivity. DNA testing of pigs of Landrace breeds of French selection on the genes RYR1, ESR, HFABP (allele systems H and D) was carried out and the association of polymorphisms of these genes with indicators of productivity was studied. In all age groups the genotype NN was identified - non-native stress resistant. It was determined that sows of ESR (BB) genotype surpassed sows ESR (AA) genotype by the number of piglets born by 1,1 animals, or 9,7%, including born alive – by 1,2 animals, or 11,1%, milkiness – by 4,7 kg, or 7,7%, the number of piglets at 21st days – by 0,8 animals, or 8,3%, and at weaning – by 0,6 animals, or 6,4%. The superiority of sows with genotype H-FABP (dd) on indicators of productivity of animals with genotypes Dd and DD was revealed. It was also determined that young Landrace pigs with genotypes H-FABP (DDHh and ddHH) had higher rates of age of reaching live weight of 100 kg – 187 and 204 days, and average daily gain – 535 and 493 g.
