| 摘 要： | 对30只河南大尾寒羊进行超数排卵处理,研究不同激素、不同季节、不同输精方式以及重复超数排卵对其超数排卵效果的影响。结果表明:采用加拿大产FSH处理,河南大尾寒羊的只均黄体数(15.76)和只均获胚数(12.76)显著高于采用新西兰产FSH组(11.78、8.78);冬季处理的河南大尾寒羊的只均黄体数(18.11)、只均获胚数(14.84)和只均可用胚数(5.21)显著高于春季(13.44、9.44、3.78)和秋季处理组(11.61、9.56、2.72);采用350 mg/只剂量FSH处理,河南大尾寒羊只均黄体数(18.27)和只均胚胎数(14.53)显著高于300 mg/只剂量组(12.23、10.23),且优于400mg/只剂量组;腹腔内子宫角输精,河南大尾寒羊只均可用胚数(4.68)显著高于阴道输精处理(1.89);重复超数排卵各次之间的只均黄体数、只均胚胎数和只均可用胚数差异不显著。 |

| Abstract: | To study the effects of hormone,season,insemination method and repeated superovulation on superovulatory response in Henan Long-tail Han sheep,a total of 30 Henan Long-tail Han sheep were investigated.The results demonstrated that the average corepus luteum(CL) and average embryos of Canada's FSH were significantly more than that of Newzealand's FSH.The average CL,average embryos and average available embryos of winter were significantly more than that of spring and autumn.The average CL and average embryos of 350mg dose of Canada's FSH were significantly more than that of 300mg,and the average available embryos of intrauterine cervices insemination were significantly more than that of aginal insemination.No significant difference among the first superovulation,the second superovulation and the third superovulation was observed. |
| Keywords: | Superovulation Embryo Corpus luteum Available embryos Henan Long-tail Han sheep |
