目的]检验绵山羊双羔素在提高辽宁绒山羊繁殖率方面的作用。方法]应用绵山羊双羔素(睾酮-3-羧甲基肟·牛血清白蛋白)在辽宁省盖州市、凤城市、瓦房店市、山西省岢岚县和河北省涞水县的绒山羊场和农户家,对1 327只2~6岁的辽宁绒山羊母羊进行免疫注射试验。结果]试验组产羔率132.93%,对照组产羔率115.77%,试验组与对照组相比产羔率和双羔率均提高17.16%,差异显著(P0.05)。结论]绵山羊双羔素可以提高辽宁绒山羊的繁殖率。

Study on Using Fecundin to Improve Reproductive Rate for Liaoning Down Producing Goat

Objectives ] This study aimed of testing the function of fecundin in improving the reproductive rate of Liaaoning down producing goal （LDP goat）. Method] Steroidal antigen （testosterone-3-ethyloic-oxime. BSA） was used as fecundin to improve reproductive rate for LDP goal in inoculation test. The test took 1 327 LDP goats, age from 2 -6 years, selected from Gaizhou, Fengcheng, Wafaingdian, Kelan and l_ztishu1 randomly, as research objects. Result] The lambing rate was 132.93% in experimental group and, that was 115, 77% in control group. The lambing rate and the double rate of lamb was improved by 17.16% and, the difference was significant （P 〈 0.05 ）. Conclusion ] The resuh1 suggested that the steroidal antigen can be used as fecundin to improve reproductive rate for LDP goat.
