摘要
对119只萨福克肉羊进行超排处理,其中48只为首次超排处理,71只为第二次超排处理。结果表明,首次超排胚胎回收率显著高于二次超排胚胎回收率(P<0.05);首次超排和二次超排间供体羊平均黄体数、胚胎可用率均差异不显著(P>0.05);供体羊经第二情期或埋栓同期发情处理后均能达到预期的效果,但首次超排和二次超排供体羊胚胎回收率均差异显著(P<0.05)。
119 suffork mutton were superovulated,include 48 were first superovulated sheep and 71 used again.The results showed that the average recovered embryos of second superovulated sheep was significantly lower than first superovulated donors（P0.05）,The number of corpus luteum was not significant different by the first and second blunt donors（P0.05）,both the available rate embryo of was not significant different（P0.05）.The synchronization of estrous through the second estrous cycle or vaginal plug methods,achieved the desired results,but both the average recovery embryos of second superovulated sheep were significantly lower than first superovulated donors（P0.05）.
