| 摘 要： | 本文旨在验证烯丙孕素保胎及2次半剂量氯前列烯醇注射的引产效果，从而缩短母猪批次分娩时间跨度。异常临产母猪群连续多天口服烯丙孕素，推迟分娩母猪群使用半剂量氯前列烯醇2针（2针间隔6 h）诱导分娩。结果表明：口服烯丙孕素试验组分娩比例为0.0%，对照组分娩比例为0.2%；注射第1针氯前列烯醇后22~32 h期间，试验组分娩比例为74%，对照组分娩比例为57%，注射第1针氯前列烯醇>56 h，对照组分娩比例为9%，试验组分娩比例为2%。结果说明烯丙孕素能有效抑制临产母猪提前分娩，2次半剂量氯前列烯醇能有效提高诱导分娩效果，减少推迟分娩比例。

| Abstract: | This study was aimed to verify fetus protection effects of altrenogest and delivery induction effects of 2 needles of half dose of cloprostenol on sows, in order to shorten their delivery interval. The abnormal parturient sows were treated with altrenogest orally for several consecutive days. Postponed delivery sows were injected by 2 needles of half dose of cloprostenol (2 needles interval 6 h) to induce parturition. The results showed that the proportion of deliveries was 0% in the test group treated with altrenogest orally and 0.2% in the control group. The proportion of births in the test group was 74% after the first injection of cloprostenol with half dose during 22 to 32 h, while 57% in the control group. The proportion of births in the test group was 2% with the first injection of cloprostenol after 56 h, while 9% in the control group. The altrenogest can effectively inhibit early delivery in sows, and injection of 2 needles of half dose of cloprostenol can effectively improve induced delivery and reduce the proportion of delayed delivery. |
