ABSTRACT / SAŽETAK:

This paper aimed to determine the effect of genotype (Large White and F1) and parity (the first five parities) on selected reproductive traits of sows. Based on the obtained results, it can be concluded there was no significant difference in the number of live-born and weaned piglets between Large White and F1 sows (p≥0.05). At the same time, parity significantly affected the number of live-born and weaned piglets (p≤0.05). Genotype did not affect piglet birth weight (p≥0.05) but significantly affected weight at weaning (p≤0.05). On the other hand, the effect of parity on birth weight and weight at weaning was significant (≤p0.05). A significant genotype x parity interaction was recorded for a number of weaned piglets and weight at weaning (p≤0.05).
