为探讨牛胚胎移植受胎率、产犊成活率及后代生长发育情况,互助县先后从新疆呼图壁种牛场胚胎工程中心引进不同品种牛冷冻胚胎93枚,进行了胚胎移植试验.结果表明:平均受胎率为45.16%,产犊成活率为90.48%.黑白花、西门塔尔、利木赞、安格斯犊牛平均初生重为40.77,42.50,47.41,39.13,分别比同龄本地牛提高71.82%,79.10%,99.79%,64.90%;六月龄平均体重分别为116.74,123.36,134.15,120.49,分别比同龄本地牛提高64.80%,74.13%,89.37%,70.09%;12月龄体重分别为253.31,289.91,302.73,271.35,分别比同龄本地牛提高75.18%,100.51%,109.36%,87.66%;1周岁平均日增重分别为582.30g,677.84g,699.50g,636.22g.胚胎移植后代牛的生长发育较本地牛快.
