优质细毛羊胚胎移植技术的研究与应用

A Study and Utilization of the Technology of Embryonic Implantation on High Quality Fine Wool Sheep

１９９４～１９９７年分别在镇南种羊场宝山分场和白城市牧草良种繁育站等地进行了优质细毛羊胚胎移植技术研究。共超排处理３３只供体羊，获卵２６１枚，其中可用胚胎２０８枚，平均每只供体羊获可用胚胎６３枚。在超排羊中有优质细毛羊１８只，获可用胚胎１２３枚，平均每只供体羊获可用胚胎６８枚。４ａ间共用鲜胚胎移植受体羊１５６只，妊娠１０５只，受胎率为６７３％。共产羔羊１０３只，每只供体羊平均获羔羊３１２只，达到了自然繁殖水平的３倍。

From 1994 to 1997,Sheep embryo transplant technigue was conducted in different livestock breeding station.33 donor sheep was over ovulation and obtained 261 eggs,298 of which were efficient,obtaining 6.3 eggs from each donor sheep in average.There was 18 fuzz sheep of the over oviposited sheep and obtained 123 efficient embryo,obtaining 6.8 embryo from each donor sheep in average.From 1994 to 1997,156 sheep were transplanted using fresh embryo,105 transplanted sheep pregnant,insemination rate was 67.3%,103 lamb were born,obtaining 3.12 lamb from each donor sheep in average.It is three times to natural breeding.
