| 摘 要： | 本试验采用FSH＋PG的方法对22头供体荷斯坦牛分两批进行了超数排卵处理,140头受体南阳黄牛和供体牛采用2次PG法分批进行了同期发情处理。结果如下：（1）共有20头供体牛、104头受体牛在第二次注射PG后96h内发情,同期发情率分别为90.90%和74.29%;（2）20头供体牛回收胚胎176枚,可用胚胎140枚/头,平均回收胚胎8.8枚/头,平均可用胚胎7.0枚/头,可用胚胎比率79.55%;（3）104头南阳黄牛受体均移植单胚,51头妊娠,妊娠率为49.04%。

| Abstract: | Superovulation was conducted on 22 Holstein cows as donors by FSH＋PG methods.There were 140 Nan Yang cattle as recipients and donors,they had been synchronized estrus by PG for two times.The results showed as follows.（1）20 Holstein cows and 104 Nan Yang cattle had estrous in 96h after the second time in PG.The percentage of synchronized estrus about Holstein cows and Nan Yang cattle were 90.90% and 74.29% respectively;（2）The total embryos collected and usable embryos obtained,the average embryos collected number and the average usable embryos obtained per donor,the usable embryo rate of 20 Holstein cows were 176,104,8.8,7.0 and 79.55% respectively;（3）One usable embryo obtained was transferred to one of 104 Nan Yang cattle,the pregnancy number was 51 and the rate of pregnancy was 49.04%. |
