绵山羊双羔素提高细毛羊繁殖率的研究

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。

Study on Improvement of Reproductive Rate of Fine-wool Sheep by Fecundin

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.
