摘要

The present study investigated the incidence of postparturient disorders and backfat loss in primiparous and multiparous sows under tropical climates in relation to duration of farrowing and type of antibiotic used postpartum. In total, 81 sows (42 primiparous and 39 multiparous sows) were included. The sows were categorised according to the duration of farrowing into three groups: < 2 (n = 58), 2-4 (n = 19) and > 4 h (n = 4). According to the antibiotic used postpartum, the sows were divided into two groups: group I (enrofloxacin type 1, n = 36) and group II (enrofloxacin type 2, n = 45). Rectal temperature, the presence of abnormal vaginal discharge, the occurrence of postpartum dysgalactia syndrome (PDS) and the sows' appetite were determined at days 0, 1, 2 and 3 postpartum. Backfat thickness was measured before farrowing and at 21 days postpartum. The mean duration of farrowing was 114.5 +/- 60.2 min. Stillborn piglets in the sows with a long duration of farrowing (> 4 h, mean 287.9 min) was higher than in sows with a short duration (< 2 h, mean 85.5 min) of farrowing (29.2 and 7.9 %, P = 0.044). Primiparous sows lost more backfat during lactation than multiparous sows (15.7 and 4.8 %, P = 0.004). The incidence of abnormal vaginal discharge (P = 0.046) and PDS (P = 0.057) was less frequent in group II than in group I sows. In conclusion, primiparous sows and sows with a long duration of farrowing had a high risk of postparturient disorders. The type of antibiotic had an effect on the incidence of abnormal vaginal discharge and PDS in sows.
