摘　　要：为了治疗母猪产后乏情,缩短母猪非生产天数,试验选取断奶超过10 d不发情、没有子宫炎症的二元杂母猪100头,随机分为4组,对照组不改变猪场原来断奶母猪的饲养管理方法,试验Ⅰ组处理方式为注射氯前列醇钠+孕马血清+绒毛膜促性腺激素,试验Ⅱ组处理方式为调整管理措施+饲喂催情散+葡萄糖,试验Ⅲ组处理方式为饲喂烯丙孕素+葡萄糖,按照以上方式处理后观察母猪发情、受胎和产仔情况。结果表明:在发情率指标中,与对照组相比,试验Ⅱ组提高了32.0百分点,差异不显著(P>0.05),试验Ⅰ组和Ⅲ组分别提高了40.0百分点和52.0百分点,差异显著(P<0.05);在受胎率指标中,试验Ⅰ~Ⅲ组分别比对照组提高了16.96百分点、10.46百分点和22.22百分点,但均差异不显著(P>0.05);在平均窝产仔数指标中,试验Ⅰ组和Ⅲ组比对照组提高了9.33%和5.36%,试验Ⅱ组比对照组降低了2.07%,各组间均差异不显著(P>0.05)。说明三种处理方式均能提高母猪的繁殖效果,在发情率和受胎率两个指标中,试验Ⅲ组最高,其次是试验Ⅰ组;在平均窝产仔数指标中,试验Ⅰ组最高,其次是试验Ⅲ组,试验Ⅱ组最低。In order to treat parturition anestrus of sows and reduce the non-productive days of sows, 100 binary hybrid sows with no heat for more than 10 days and no uterine inflammation were randomly divided into 4 groups. Weaned sows in the control group continued to use the original breeding and management methods of the pig farm. Weaned sows in the experimental groupⅠ were injected chloroprostenol sodium + pregnant horse serum + chorionic gonadotropin. Weaned sows in the experiment group Ⅱ was treated by adjusting management measures + feeding aphrodisiac powder + seeding glucose. Weaned sows in the experiment group Ⅲ was treated by feeding allyl progestin + glucose. The estrus, fetation and litter of sows were observed during the experimental period. The results showed that the estrus rate and conception rate of post-parturient anestrus sows could be improved by the treatment of group Ⅰ-Ⅲ. The estrus rate of GroupⅡ increased by 32.0% compared with the control group, but the difference was not significant(P>0.05). The estrus rate in the experiment groupⅠand Ⅲ significantly increased by 40.0% and 52.0%, respectively, compared with the control group(P<0.05). The conception rate in the experiment group Ⅰ-Ⅲ increased by 16.96%,10.46%, and 22.22%, respectively, compared with the control group, but the difference was not significant(P>0.05). The average litter size of test group Ⅰ and Ⅲ significantly increased by 9.33% and 5.36%, respectively, compared with the control group;and the average litter size of test group Ⅱdecreased by 2.07%;but the difference was not significant(P>0.05). The results indicated that three treatments all could improve the reproductive efficiency of sows, among the two indexes of estrus rate and conception rate, Group Ⅲ was the highest, group Ⅰwas the second;for nest average litter size indicators, group Ⅰwas the highest, Group Ⅲ was the second, and Group Ⅱ was the lowest.
