摘　　要：母羊同期发情技术是发情控制的基础,也是胚胎移植的重要环节。目前,利用外源激素控制绵羊同期发情方法主要有孕酮控制释放装置(CIDR)、阴道内醋酸氟孕酮海绵栓(FGA)、两次前列腺素(PGF2α)、促性腺激素释放激素(Gn RH)+前列腺素(PGF2α)等,这些方法被广泛用于生产,以诱导排卵、促进同期发情、同步分娩,进而提高绵羊的生产力。然而,在实际应用过程中,各种方法在处理时间、生殖道感染、发情率、受胎率等方面都存在差异。笔者比较了这几种技术的优缺点,为生产和试验提供参考。Simultaneous oestrus technology is the basis of oestrus control and an important link of embryo transfer.At present,the methods of controlling sheep estrus by using exogenous hormones include:controlled internal drug release (CIDR)method;fluorogestone acetate (FGA)sponges ;Two prostaglandins (PGF2);Gonadotropin releasing hormone (GnRH)+prostaglandin(PGF2),etc.,are widely used in production to induce ovulation,promote simultaneous oestrus,and synchronize childbirth to improve sheep productivity. However,in the actual application process,each method has differenee.s in treatment time,reproductive tract infection,oestrus rate, pregnancy rate and other aspects.This paper focuses on the technical details of these aspects and compares their advantages and disad- vantages,providing reference for production and test.
