title: The effect of postparturient urogenital diseases on the lifetime reproductive performance of sows.
abstract: To prove the effect of postparturient swine urogenital disease (SUGD) on reproductive performance, culled sows with SUGD in their previous history (n=1363) were subjected to retrospective lifetime production analysis. The sows were assigned to parity groups 1, 2 to 6, and >6. Bacterial flora of vulval discharges were evaluated. Parity 1 sows had a lower percentage of SUGD than did sows of parity 2 to 6 and parity >6 (P < 0.05 and P < 0.01, respectively). Compared with parity 2 to 6 sows, parity 1 and parity >6 sows had lower (P < 0.001) conception, farrowing and adjusted farrowing rates, lifetime average total born, live-born litter sizes, stillbirth rates, and weaning litter weights compared with animals culled for other reasons than SUGD. The conclusions are that high parity sows have a higher occurrence of postparturient SUGD and that higher parity sows with postparturient SUGD have a lower performance compared with lower parity sows with postparturient SUGD.
