The aim of this study was to determine the fertility and pregnancy loss of sows F1 hybrid, Large White x Landrace at ages 2-5 years, in intensive industrial exploitation with  artificial insemination. After the artificial insemination until 28 days of pregnancy, animals were housed in individual and open pens - with the goal to see how the type of pen influences on fecundity and pregnancy loss, calculated at 28 and 56 days. The results were analysed using χ2 test. Fecundity at 28 days for sows housed in individual pens was higher than for sows housed in group pens, but the difference was not statistically significant (χ2 test p≥0.05). The same was found in terms of the index of fecundity diagnosed in 56 days. Pregnancy loss from 28 to 56 days after the artificial insemination was 1.83 ± 0.40 for sows housed in individual pens and 2.14±1.38 for sows housed in group pens, the difference being statistically not significant (χ2 test p≤0.05). The higher the number of animals in group pen, gestation losses were higher reaching 16.24±1.12 for sows kept in pens with a capacity of 10 heads, very significant difference comparing to animals kept in pens 5 and 7 (χ2 test p≤0.001). The difference between animals kept in pens of 7 and 10 animals was not statistically significant (χ2 test p≥0.05). The best results were obtained if up to 28 days after the artificial insemination sows were housed in individually and in late gestation when the sows were housed in group pens with size varied between 5 to 7 sows.
