摘　　要：本实验利用CIDR+PMSG对绵羊进行同期发情处理。并分别用不同LH剂量对86只受体绵羊进行了诱发排卵试验:方法一100IU,方法二200IU,方法三300IU的。结果表明,CIDR+PMSG法同期发情率为:95.3%,第1d的发情率(61%)显著高于第2d的发情率(39%)(P<0.01)。方法一的优质黄体率(55.2%)显著高于方法二的优质率(26.9%)(P<0.05),方法一(55.2%)与方法三(34.6%)之间的优质率差异不显著,但方法一比较节省药品。因此,方法一的效果最好。In this study the synchronized estrus of sheeps were induced by CIDR ＋ PMSG, experiments of ovulation induction were performed on 86 of Recipient Sheeps by difference LH dosages with three methods （Method 1 100IU,Method 2 200IU and Method 3 300IU）. The results revealed that the percentages of synchronized estrus were 95.2 % totally, percentage of synchronized estrus at the first day was 61%, percentage of synchronized estrus at the second day was 39%, percentage of synchronized estrus at the first day was obviously higher than at second day （P〈 0.01）. High quality corpus luteum（55.2%） which ovarys contain through the treatment of method 1 was significantly superior to that （26.9%） through method 2 （P〈0.05）,but no striking diference existed between method 1 and method 3, in chemical could be saved by using method 1 . the treatmentof experiment more 1.
