进口肉羊冷冻胚胎移植试验

Research of mutton sheep frozen embryos transfer technology

该研究对从澳大利亚引进良种肉羊无角陶赛特、得克萨尔、萨福克冷冻胚胎进行移植。得到以下研究结果 :A级黄体受体羊移植成功率 5 5 .3% (99/179) ,B级黄体受体羊移植成功率 38.1% (8/2 1) ,统计差异极显著 (P <0 .0 1) ;移植 1枚胚胎的妊娠率 4 8.4 % (6 3/130 )显著低于 (P <0 .0 5 )移植 2枚胚胎的妊娠率 6 2 .9% (4 4 /70 ) ;移植速度 2～ 4min的妊娠率(5 8.2 % )极显著高于 (P <0 .0 1)操作困难 (10min以上 )的妊娠率 (2 8.6 % )。

Mutton sheep frozen embryos of Poll Dorset?Texel?Suffolk from Australia were transplanted to 200 recipients. There was extremely significant effect (p<0.01)of corpus luteum grade of recipients on the pregnant rate, with 55.3 %(99/179)for grade A and 38.1%(8/21)for grade B respectively. There was extremely significant difference of the speed of transfer on pregnant rate.
