The aim of the study was to evaluate the results of reproductive traits of one tested hybrid combination (CLW x CL) x D and to evaluate the influence of Duroc boars which were used in the test. The following characteristics were compared in the study: number of all born piglets, number of live born piglets, number of weaned piglets, weights at birth and at weaning. Fifty-six F1 sows (CLW x CL) and five Duroc boars were tested. The average number of all born piglets was 13.86, live born piglets 12.61 and weaned piglets 11.13. The highest number of live born piglets per sow was obtained with the boar HAI 35 (13.63 on average), whereas the boar HAI 34 had the worst results (11.9 piglets on average). Numbers of weaned piglets were well-balanced in boars DUR 363 and HAI 35 (more than 11.6 of weaned piglets per litter on average). The lowest number of weaned piglets (10.3 on average) was obtained with the boar HAI 34. Nevertheless, the differences in the number of all born, live born and weaned piglets were not significant. There was a significant difference in the average birth weight between sexes and also among the boars (1.51 kg in male piglets vs. 1.42 kg in gilts). The lowest birth weights were observed with the boars DUR 363 (1.37 kg) and HAI 35 (1.39 kg). The average birth weights of piglets of the other three fathers were around 1.5 kg.
