【摘要】：在进行常规超数排卵后,针对苏尼特羊及乌珠穆沁羊的超数排卵效果进行分析,希望从排卵数、黄体数、胚胎状态等数据间发现2种绵羊超数排卵效果的差异,为后续研究提供数据基础。苏尼特羊16只和乌珠穆沁羊8只2种低产地方品种的母羊进行常规同期发情和超数排卵处理,随后对发情绵羊进行配种,并在6.5d后进行冲胚操作,统计卵巢黄体数、采胚数和可用胚胎数,分析2种绵羊间的超数排卵效果差异。苏尼特羊和乌珠穆沁羊同期发情率无显著差异P=0.439(P0.05),但苏尼特羊同期发情效果优于乌珠穆沁羊,分别为87.5%和75%;苏尼特羊与乌珠穆沁羊的头均黄体数间无显著差异(P0.05);苏尼特羊与乌珠穆沁羊的头均采胚数间差异极显著(P0.01),苏尼特羊优于乌珠穆沁羊;苏尼特羊与乌珠穆沁羊的头均可用胚胎数间差异极显著(P0.01),苏尼特羊优于乌珠穆沁羊。苏尼特羊和乌珠穆沁羊间的超排效果存在差异。
[Abstract]:After routine superovulation, the superovulation effects of Sunita sheep and Wuzhimuqin sheep were analyzed. It was hoped that the difference of superovulation effect of two kinds of sheep could be found from the data of ovulation number, luteal body number and embryo status. To provide the data basis for the follow-up study. The estrus and superovulation of 16 Sunita sheep and 8 female estrous sheep of two kinds of low yield local breeds were treated with routine simultaneous estrus and superovulation, and then the oestrous sheep were bred, and the embryos were flushed after 6.5 days to count the number of corpus luteum. The number of embryos collected and the number of available embryos were used to analyze the difference of superovulation effect between the two kinds of sheep. There was no significant difference in estrus rate between Sunita sheep and Wuzhimuqin sheep (P0.05), but the estrus synchronization effect of Sunita sheep was better than that of Wuzhimuqin sheep. There was no significant difference in the number of corpus luteum between Sunita sheep and Wuzhoumuqin sheep (P0.05), and there was significant difference between Sunita sheep and Wuzhumqin sheep (P0.01), and Sunita sheep was superior to Wuzhoumuqin sheep. There were significant differences in the number of embryos between the Sunita sheep and the Wudhumuqin sheep (P0.01), and the Sunita sheep was superior to the Wuzhimuqin sheep. There were differences in superovulation between Sunita sheep and Wuzhimuqin sheep.
