摘　　要：[目的]为了分析河南三种肉牛超数排卵效果。[方法]分别选择夏南牛、郏县红牛、南阳牛作为试验母牛,采用两次PG+促卵泡素(FSH)的方法对试验母牛进行超数排卵,观测试验母牛获得总胚胎数、可用胚数分析超数排卵效果。[结果]结果显示,夏南牛可用胚9.86枚/头,南阳牛可用胚7.71枚/头,郏县红牛为6.75枚/头,可用胚中夏南牛最高与郏县红牛和南阳牛有显著性差异。可用胚率郏县红牛最高79.41%,显著高于夏南牛和南阳牛。[结论]结果表明,PG+FSH法可以用于夏南牛、郏县红牛和南阳牛的超数排卵。[Objective]To analyze the effect of superovulation in Henan three beef cattle.[Methods]Xia’nan cattle,Jiaxian Red cattle and Nanyang cattle were selected as experimental cows respectively,and the method of PG+FSH was used to superovulate the experimental cows,the total number of embryos obtained and the effect of superovulation were observed and analyzed.[Results]There were 9.86 embryos each cow in Xia’nan cattle,7.71 embryos each cow in Nanyang cattle and 6.75 embryos each cow in Jiaxian red cattle.The available embryo rate of Jiaxian red cattle was 79.41%,which was significantly higher than that of Xianan cattle and Nanyang cattle.[Conclusion]The results showed that PG+FSH method could be used for superovulation in Xia’nan cattle,Jiaxian Red cattle and Nanyang cattle.
