摘要
选择60头本地黄牛进行同期发情和胚胎移植研究,结果表明:CID-B和ODB处理组的同期发情率显著高于PMSG和PG的处理组(p<0.01),60头受体牛中,黄体合格进行胚胎移植的共23头,移植率30.4%,产犊率26.1%,其中A,B级胚胎在移植受体中差异不显著(p>0.05)。
A total of 60 local cattle are selected to study on the synchronized estrus and embryos transfer. The results show that the best methods of synchronized estrus are CIDR-B and ODB, which are significantly higher than that of PMSG and PGF2a （P〈0.01）. Among 60 transfer receptor cattle, there are 23 cattle with acceptable yellow body receipt the embryos transfer, the embryO transfer percentage is 30.4%, and the production percentage is 26.1%. But there is no obvious difference in the conception rate of grade A embryo and grade B embryo （P〉0.05）.
