| 摘 要： | 本文比较了荷斯坦牛、西门塔尔牛和新疆褐牛青年母牛的超排效果。结果表明,荷斯坦牛、西门塔尔牛和新疆褐牛的平均卵回收分别为10.51枚、13.59枚和13.82枚;平均有效胚胎分别为5.12枚、5.94枚和6.66枚。在胚胎发育阶段上,3个品种间也存在着差异。由此得出结论：不同品种间超排反应和有效胚胎产量存在着差异,乳肉兼用牛优于乳用牛。

| Abstract: | The comparison of superovulation response was made among three breeds of heifers：Holstein,Simmetal and Xinjiang Brown.The results showed that the average eggs recovery in Holstein,Simmental and Xinjiang Brown was 10.51,13.59 and 13.82, respectively and transferable embryos were 5.12,5.94 and 6.66,respectively.At the stage of embryo development,there were some differences among three breeds.In conclusion,there are some differences in superovulation response and transferable embryo yield among different breeds.Milk-meat purpose cattle was better than milk-purpose cattle. |
