The aim of the study was to evaluate productive and reproductive performance of Prestice Black-Pied sows including losses of piglets from birth to weaning in conditions of two farms. The experiment involved one hundred sows of Prestice Black-Pied pig from the 1st to the 7th parity (50 from farm A and 50 from farm B). The evaluation of productive parameters revealed a highly statistically signifcant difference (P = 0.001) between gilts of the observed farms in percentage of lean meat. Backfat thickness was 0.19 cm lower in gilts from the farm A, which is a very highly statistically signifcant difference (P = 0.001). The evaluation of reproductive performance showed, that age at the time of the frst insemination and farrowing was signifcantly higher (P = 0.05) in gilts from the farm A compared to gilts from the farm B by 38 days on average. The analysis also indicates that there was no signifcant difference in length of gestation, total number of piglets and numbers of live-born and reared piglets between the sows of the evaluated farms. A highly statistically signifcant difference (P = 0.01) was found in number of stillborn piglets. Interval length was signifcantly longer (P = 0.05) in sows from the farm A, by 14.29 days. The evaluation of losses of piglets revealed a signifcant difference (P = 0.05) between the farms in favor of piglets from the farm A.
