The aim of the research was to determine the fertility of purebred sows (Large White - LW, Landrace - L, Swedish Landrace - SL, Danish Landrace - DL, Duroc - D, Pietrain - P, Hampshire - H, Norwegian Landrace - NL, German Landrace - Ne.L.) and seven F1 hybrid genotypes (Landrace and Large White). The influence of genotype and parity of sows on litter size traits (Number of live born piglets - NLBP, number of stillborn piglets - NSP, total piglets born - TPB, number of reared piglets and litter weight) and lactation duration was examined. Research showed that the highest number of live born piglets was in F1 crossbreeds (13.36 NLBP), while among purebreds the highest NLBP was in the Landrace breed (12.44 NLBP) and Large White (12.17 NLBP). Looking at parities for all tested genotypes, NLBP in the first litter was over 11.53 piglets. For breed L and LW, the highest NLBP was in the fourth litter 12.88 and 12.55 piglets. F1 crosses LxLW (♀Lx♂LW) also had the highest NLBP in the fourth litter 12.85 piglets. For the genotype F1 crosses LWxL (♀LWx♂L), the highest average number of live-born piglets was 12.32 piglets in the second and third litters. Variation in litter size at birth and weaning by genotype and parity was statistically significant (P<0.01), except for the number of stillborn piglets of L sows by parity, where a significant difference was found (P<0.05).
