| 摘 要： | 目的]研究分胎次饲养提高繁殖母猪生产性能的可行性。方法]将头胎、二胎、三胎母猪分开饲养后进行人工授精,并将一胎母猪后代猪群与二胎以上母猪后代猪群实行隔离饲养,记录每头母猪年产仔数和地方性肺炎病变等数据。结果]分胎次饲养的头胎母猪平均年产断奶仔猪22.5头,二胎母猪平均年产断奶仔猪24.2头,三胎母猪平均年产断奶仔猪22.3头,不同胎次母猪平均年产断奶仔猪22.8头,头胎母猪的生产水平接近平均水平。头胎母猪后代的地方性肺炎病变率为31%,二胎以上母猪后代的地方性肺炎病变率是11%,为头胎母猪后代发病率的1/3,稳定了二胎以上母猪的健康水平。结论]集约化分胎次饲养可提高猪场后备母猪的生产性能。

| Abstract: | Objective] The study was to research the feasibility of dividing fetus feeding to increase the productive performance of breeding sows.Method] The first-born,second-born and third-born breeding sows were separated to be fed,after that they were artificially fecundated.The progeny swinery of the first-born and more than the second-born breeding sows were separated to be fed and the annual production litter size and pathological change of local pneumonia for breeding sows etc.were recorded.Result] After fetus disparting feeding,the first-born breeding sows could produce the weaned piglets of 22.5,and the second-born breeding sows could produced the weaned piglets of 24.2 and the number for third-born breeding sows was 22.3,with the average number of weaned piglets in different fetus of 22.8.The production level of the first-born breeding sows was close to the average level.The pathological lesion rate caused by local pneumonia for the progeny swinery of the first-born sows was 31%,and that for the second-born breeding sows was 11%,being 30% of the pathological lesion rate in the first-born sows,so the health level of more than the second-born breeding sows was more stable.Conclusion] Intensive fetus disparting feeding could increase the productive performance of gilts in pig fram. |
