摘 要：
以乌珠穆沁蒙古绵羊及无角道赛特羊为供体,采用FSH-LH法,对73只供体羊实施超排处理,有效率为94.5%,平均获卵8.12枚,平均获可用胚7.22枚。结果表明:在9～11月超排效果最佳;发情周期正常且易受孕,母羊可提高超排效果和胚胎可用率;FSH剂量150IU可获较好的超排效果;适龄羊超排效果最佳,平均获卵和可用胚胎数高于育成和老龄羊组。

摘 要：
With Wuzhumuqin Mongolia sheep and Poll Dorset sheep as donor sheep,73 donor sheep were treated for superovulation by using FSH-LH method,the effective rate was 94.5 %,the average obtained eggs were 8.12 and the average acquired useful embryos were 7.22. The result indicated that the best month for superovulation effect was from Sep. to Nov.; the estrous cycle was normal and easy to be pregnant,the superovulation effect and embryo available rate of ewes could be improved. The good superovulation result would be attained with 150 IU of FSH dosage; the sheep with right age had the optimal superovulation effect,with the numbers of average attained eggs and available embryos being higher than that of bred and aged sheep groups.
