This study evaluated female lifetime productivity in a swine integration system of Brazil that combines segregated gilt development units called fourth sites (4S) and sow farms (SF). Records of 5,013 culled females from 3 4S and 10 SF were evaluated. The most frequent culling reasons were locomotor problems, in 4S, and litter performance, in SF. Days in herd at culling were 71.8 ± 0.8 in 4S. In SF, parity at culling was 4.4 ± 0.1; the lowest number of pigs born during lifetime (33.5 ± 1.1) was for females culled due to reproductive failures and the lowest number of pigs born per year of lifetime (22.8 ± 0.3) was for sows culled due to litter performance (P < 0.05).
