Therefore, the aim of our research was to assess the impact of the season, microclimatic indicators and technology of housing of the lactating sows on the number of the weaned piglets in the litter. The experiment was performed on a production farm in Slovakia and a total of 800 litters were evaluated. The results have shown that the season had a statistically significant effect on the number of the weaned piglets ( p

In the experiment, we investigated the effect of the hybrid combination and sex on the fattening parameters of pigs fed with the same feed. The analyzed group consisted of 27 animals. We used the final hybrids of BU x L x PIC and BU x PIC for the testing purposes. Feeding pigs with the mixture was the same for all the tested pigs. We evaluated the average daily gain (ADG) in grams (g), feed consumption ratio (FCR) in kilograms (kg), number of feeding days (FD) in two growth phases: Phase 1 - piglets (from weaning to 25 kg), Phase 2 - test (30-100 kg). The pigs of the hybrid combination LW x L x PIC (ADG – 533.6 g, p
