为探索青年供体母羊提前扩繁的利用效率，本研究选择12只周岁龄德国美利奴母羊作为供体羊，分两组注射不同剂量FSH进行超排，两组分别平均获可用胚枚1．16枚和4．3枚，组间差异明显（P〈0．01），总受胎率59．4％。该结果表明周岁龄德国美利奴羊对超排敏感，可用于胚胎生产，建议实际生产中应适当提高FSH注射剂量。

In this study, 12 yearling German Merino ewes were selected as embryo donors, randomly divided into two groups and treated with two different doses of FSH (14ml and 16ml respectively) for superovulation. The transferable embryos collected from the two groups were 9 and 26, respectively, and the difference was significant (P 〈 0.05). The overall conception rate was 59.4%. The results show that primiparous German Merino sheep are responsive to superovulation with FSH, and can be used for embryo donors; When primiparous sheep are used as embryo donors, it is recommended to mndarnlo]v inorgn.,~ th,~ ct ~ V~I4
