摘要
[目的]提高细毛羊的繁殖潜能，增加农牧区养殖者的经济效益。[方法]应用绵山羊双羔素（睾酮－3－羧甲基肟·牛血清白蛋白），在新疆巩乃斯种羊场、甘肃天祝种羊场、青海三角城种羊场和黑龙江齐齐哈尔种羊场开展免疫试验。[结果]巩乃斯种羊场试验组产羔率为143．68％，对照组产羔率为125．10％，试验组产羔率比对照组提高了18．58％；天祝种羊场试验组产羔率为129．34％，对照组产羔率为102．71％，试验组产羔率比对照组提高了26．63％；三角城种羊场试验组产羔率为114．80％，对照组产羔率为104．84％，试验组产羔率比对照组提高了9．96％；齐齐哈尔种羊场试验组产羔率为150．62％，对照组产羔率为119．67％，试验组产羔率比对照组提高了30．95％。[结论]只要加强饲养管理，绵山羊双羔素可以提高细毛羊的繁殖率。
Abstract
Objective] The aims were to excavate reproductive potential of fine-wool sheep, to improve the economic benefits of farmers in agri-cultural and pastoral areas.[Method]The steroidal antigen (testosterone-3-ethyloic-oxime· BSA) was used as fecundin to immunize fine-wool sheep for inoculation test in Gongnaisi Sheep Breeding Farm of Xinjiang Province, Tianzhu Sheep Breeding Farm of Gansu Province, San-jiaocheng Sheep Breeding Farm of Qinghai Province and Qiqihaer Sheep Breeding Farm of Heilongjiang Province.[Result] In Gongnaisi Sheep Breeding Farm, the lambing rate was 143.68%in experimental group and that was 125.10%in control group, the lambing rate was improved by 18.58%.In Tianzhu Sheep Breeding Farm, the lambing rate was 129.34% in experimental group and that was 102.71% in control group, the lambing rate was improved by 26.63%.In Sanjiaocheng Sheep Breeding Farm, the lambing rate was 114.80% in experimental group and that was 104.84% in control group, the lambing rate was improved by 9.96%.In Qiqihaer Sheep Breeding Farm, the lambing rate was 150.62% in experimental group and, that was 119.67% in control group, the lambing rate was improved by 30.95%.[Conclusion] The reproductive poten-tial of fine-wool sheep can be greatly improved through application of fecundin, provided feeding and management were strengthened.
