摘　　要：本试验对酒泉地区不同品种、年龄、胎次、体况受体牛的胚胎移植效果进行了分析研究.结果发现,移植妊娠率为：西杂受体牛（52.42％）＞土杂受体牛（47.78％）＞中国荷斯坦受体牛（46.94％）;2～6周岁的受体牛移植妊娠率（51.94％）高于7岁以上的受体牛（40.56％）;经产1～3胎受体牛移植妊娠率（51.61％）高于4胎以上牛（51.28％）和育成牛（47.06％）;体况上等受体牛的移植妊娠率（52.31％）高于体况中等受体牛（48.87％）.其中除2～6周岁与7岁以上受体牛的移植妊娠率差异极显著外（P＜0.01）,其余均差异不显著（P＞0.05）.The breed,age,parity,body condition of receptor cattle and other factors which affected embryo transfer pregnancy rate in Jiuquan region were studied.The results showed that the transplantation pregnancy rate of Simmental crossbreeding cattle receptor （52.42％） ＞ transplantation pregnancy rate of native yellow cattle receptor （47.78％） ＞ transplantation pregnancy rate of Chinese Holstein receptor （46.94％）.The transplantation pregnancy rate for receptor of 2 ～ 6 years old （51.94％） was higher than the cows above 7 years old （40.56％）.The transplantation pregnancy rate for multiparous receptors of 1 ～ 3 parities （51.61％） was higher than the cows of more than 4 parities （51.28％） and hiefers （47.06％）.The transplantation pregnancy rate of receptor with excellent body condition （52.31％） was higher than the receptor with medium body condition （48.87％）.There was no significant difference on the transplantation pregnancy rate （P＞0.05） besides the difference between the receptor of 2 ～ 6 years old and the cows above 7 years old （P＜0.01）.
