摘要
制备１１４枚冷冻胚胎，经非手术移植后得胚胎犊牛６８头。移植后４０ｄ妊娠率为７１．０５％（８１／１１４），其中育成受体牛的妊娠率为８８．１０％（３７／４２）；１００ｄ妊娠率为６４．９１％（７４／１１４），其中育成牛的妊娠率为８３．３３％（３５／４２）。ＤＮＡ指纹图亲子鉴定结果显示供体母牛与胚胎小牛个体间共有率为０．６６，而受体母牛与所生胚胎小牛个体间共有率为０。
After preparing 114 frozen embryos from Canadian Holstein, we have got 68 ET calves by nonsurgical embryo transferring. 40 days after transplant, the total pregnaney rate is 71. 05 %(81/114), the pregnancy rate of 1. 5 years old recipients is 88. 10% (37/42) land 100 days after transplant, the total pregnan cy rate is 64. 91 % (74/114), the pregnancy rate of 1. 5 years old recipients is 83. 33% (35/42). The result of parent-offspring examination identified by the technique of DNA fingerprinting shows that the band sharing probability is 0. 66 between donor cow and ET calf and is 0 between recipient cow and ET calf.
