绵山羊双羔素提高中国美利奴羊产羔率的研究

Study on Improving Chinese Merino Reproductive Rate Improved by Fecundin

[目的]检验绵山羊双羔素的免疫效果,提高中国美利奴羊的繁殖率,增加养羊的经济效益。[方法]应用绵山羊双羔素(睾酮-3-羧甲基肟·牛血清白蛋白),在新疆维吾尔自治区巩乃斯种羊场和新疆生产兵团76团分别免疫中国美利奴新疆型羊841只和军垦型羊3 502只。[结果]新疆型试验组产羔率为143.68%,对照组产羔率为125.10%,试验组比对照组提高产羔率18.58%;军垦型试验组产羔率为120.27%,对照组产羔率为105.05%,试验组产羔率比对照组提高15.22%。[结论]绵山羊双羔素可以提高中国美利奴新疆型和军垦型羊的产羔率。

This study aimed of testing immune effect of the fecundin,exploring reproductive rate of Chinese Merino and improving economic benefit for farmers in producing areas of Chinese Merino. [Method]In Gongnaisi Sheep Breeding Farm and Xinjiang production corps 76 regiment,the Xinjiang Uygur Autonomous Region,the steroidal antigen（testosterone-3-ethyloic-oxime. BSA） was used as fecundin to improve reproductive rate for Chinese Merino in inoculation test. The test took 841 Xinjiang type sheep and 3502 Junken type sheep as research objects. [Result]In Xinjiang type sheep group,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%（P 0. 05）. In Junken type sheep group,the lambing rate was 120. 27% in experimental group and,that was 105. 05% in control group,the lambing rate was improved by 15. 22%（P 0. 05）. [Conclusion]The results suggested that the steroidal antigen can be used as fecundin to improve reproductive rate for Chinese Merino.
