| 摘 要： | 本试验分别采用CIDR+E2法和两次PGF2α子宫输注法,对胚胎移植受体牛做同期发情处理,鲜胚移植观察其妊娠情况。试验结果表明两种处理方法的受体牛在24~48h发情率分别为85.5%和51.6%,两者之间差异显著(P<0.05)。移植前对受体牛进行黄体检查,黄体合格率分别为79.3%和77.8%,差异不显著(P>0.05);受胎率分别为45.8%和42.4%,差异不显著(P>0.05)。24h后观察发情,6.5d直检,黄体A、B级者用于移植。

| Abstract: | The method of CIDR＋E2 and twice use of uterine PGF2α infusion method were used in this study, embryo transfer for cattle estrus synchronization and fresh embryo transfer pregnancy was observed. The results showed that receptor bovine estrous rate at 24--48h was 85.5% and 51.6%, there was significantly difference between them （P〈0.05）. Cattle before transplantation luteal receptor inspection pass rate was 79.3%, 77.8%, there was no significant difference （P〉0.05）. Conception rate was 45.8% and 42.4%, the difference was not significant （P〉0.05）. Estrus observed after 24h, 6.5d for direct examination Cattle with luteinizing for A, B grade can be used for transplantation. |
