The profitability of pig breeding is influenced primarily by the reproductive performance of sows and at the same time reproductive performance is the basic indicator of breeding quality. In this study was compared reproductive parameters of sows from two different types of herds. Based on literature is possible to assume that sows from intensive pig breeding have worst lifelong reproductive performance because of overloading. In this study 42 sows from small pig breeding and 464 from intensive pig breeding were evaluated. Both farms breed hybrids Czech Landrace and Czech Improved White. For all sows was found average lifelong performance. Our results show that sows from small pig breeding achieved higher number of lactation for whole life by 2.04 and they were removed from the breeding later (P< 0.0001). Number of total live born piglets was higher for sows from small pig breeding by 11.59 %, but the average number of piglets per litter was higher for sows from intensive pig breeding by 23.35 % (P< 0.0001). In conclusion, sows from intensive pig breeding have better reproductive performance despite maximum use of reproductive potential of sows and overloading more of them. This result should be great benefit for every pig breeding. Maximum use of reproductive potential of sows can have positive effect for economy of farms and it has no negative effect on reproductive performance of sows.
