The aim of this diploma thesis was to analyze reproductive performance of sows in the selected breed. In this breed, data was collected in the year 2016 and early 2017. The basic statistical characteristics were monitored for the number of all pigs born, the number of live births and the number of weaned piglets evaluated for the influence of litter rank and the influence of the boar used. The test data was tested by paired t-test. The total number of sows with reproductive parameters was number 63. The number of live piglets in the monitored period was 12.9 pieces / litter. The indicator of the number of weaned piglets was 11.9 pieces / litter. The highest average number of live-born piglets was 36 for boar, but for the change had the highest piglet losses against other boars. The litter's influences on the number of live-born piglets was 12.8 pieces / litter in the 2nd litter and in the 3rd litter 13.5 pieces / litter, this difference was statistically significant. It follows that the highest average number of live piglets in litter rank was reached on the third litter order.
