As a result of conducted research it is determined that genotype ESRBB influences positively on a newly-born piglets, including live-born, piglets in 21th day and piglets before weanling. Tendency of litter weight growth is determined at birth, in 21th day and by weanling period, as well as piglets safety growth, decrease in defective farrowings percentage and percentage of dead-born piglets by sows with ESRBB genotype. While studying the pleiotropic effect of ESR gene no negative influence on these productive traits was determined
