Abstract
The research covered 42 primiparous gilts Polish LargeWhite. Sows’ body weight at first day of mating and 30th, 60th, 90th, 110th day of pregnancy and the day of weaning was controlled. Significant (P <= 0.05) positive coefficients of phenotypic correlations was estimated between body weight of sows in 30th day in pregnancy and number of piglets born alive (0.305*) and between body weight of sows in 30th, 60th, 110th day of pregnancy and number of piglets weaning (0.304*, 0.302*, 0.309*). Significant (P <= 0.01) positive coefficients of phenotypic was found between body weight of the sows to study of pregnancy phase and weight of litter and weight of piglet in 21th day of rearing (from 0.406** to 0.655**). The obtained results show that body weight of sows in pregnancy affected on their reproductive performance, especially the results offspring rearing.
