As a result of research the genetic structure on RYR1 and H - FABP genes of different populations of Belarusian Meat Breed of pigs was analyzed. The fattening productiveness indexes growth is determined among animals with H - FABPHH and H - FABPdd genotypes. The regularity of decrease of 100 kg live weight gain indexes (188,9 days) was determined, as well as forage spends per 1 kg of weight gain (3,68 forage units) and average daily weight gain (718 kg) within animals of RYR1NNH - FABPHHH - FABPdd genotypes that surpassed their coevals with RYR1NNH - FABPHHH - FABPDd genotype at 3,6 days, 0,23 forage units and 44 g correspondingly. The regularity of fattening productiveness indexes improvement up to 5% shows the possibility of the given genotypes usage as markers for selection of pigs at growth energy and speed raise
