The set of 683 piglets from 64 litters was evaluated in the nucleus herd of White meaty breed. The piglets were weighed individually with 24 hours after parturition, on 21st day and at weaning on 35th day. Average live weight was 1.42 kg in the first evaluation irrespective of the order of litter and sex. The individual weight of piglets was 5.59 kg and 7.90 kg on 21st and 35th day, respectively. The litter weight at birth was 15.32 kg, 59.65 kg on 21st day, and 84.50 kg on 35th day. The average daily gain of pigs was 0.199 kg from birth to 21st day, and 0.185 kg from birth to the weaning on 35th day. There were no statistically significant differences between gilts (n=350) and young barrows (n=333) in the evaluated parameters. The results of this work show that the litter weight on 21st day is more influenced by the number of pigs in the litter than by their weight.
