| 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.

| Abstract: | 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 woul... |
