春冬两季受体山羊同期发情和胚胎移植效果研究
Studies on the Effects of Receptor Goats Synchronization of Estrus and Embryo Transfer in Spring and Winter
-
摘要: 采用放置CIDR结合注射PM SG方法分别在春季和冬季对154只受体山羊进行同期发情处理，并在发情后第7天进行胚胎移植．结果表明：处理羊只春冬两季的同期发情率分别为90.54％和75.00％；有效发情率分别为81.08％和60.00％；妊娠率分别为61.67％和45.83％；产羔率分别为75.00％和54.17％，差异均极具有统计学意义（ p＜0.01）；春季和冬季发情羊排卵并形成功能黄体的比率分别为89.55％和80.00％，差异不具有统计学意义（p＞0.05）．说明季节对山羊同期发情和胚胎植移效果有一定的影响，但对已发情的羊只形成功能黄体比率影响不明显．

Abstract: In spring and winter ,154 receptor goats were disposed by synchronization of estrus with progester‐one‐containing intra‐vaginal sponges(CIDR) plus PMSG method ,and embryo transfer was performed on the seventh day after estrus .The results showed as follows :synchronized estrus rate in spring and winter were 90.54% and 75.00% ,respectively (p 0.05) . Thus indicating the season has certain influence on the goat estrous synchronization and embryo transfer effect , but the estrous goats form a functional corpus luteum ratio was not affected . -
