| 摘 要： | 前列腺素F2α(prostaglandin F2α,PGF2α)是一种黄体溶解因子,广泛用于母猪的同期发情和分娩启动。近年来还陆续发现PGF2α的新功能,内源性PGF2α可作为哺乳动物的妊娠识别信号,与胎体和子宫内膜PGF2α受体(PGF2α receptor,FP)结合,启动下游信号通路,对早期胚胎发育、着床、妊娠维持发挥重要作用,缺乏或合成不足会导致妊娠中断或流产。鉴于PGF2α对母畜繁殖活动的促进作用,兽药中心研发了多种PGF2α药物,如氯前列醇钠、地诺前列腺素F2α等,被广泛用来启动分娩和促进发情。根据氯前列醇钠的旋光性,可分为D-型和L-型两种对映体,其中D-型结构是氯前列醇钠的主要活性成分。外源性PGF2α药物不仅可以诱导母猪同期发情与同步分娩、促进产后健康,提高断奶母猪发情率,还可以改善母猪泌乳力与初乳质量,提高仔猪活力等生产性状。作者综述了近几年国内外PGF2α的研究进展,包括PGF2α对周期黄体的双重作用,PGF2α对早期胚胎的发育、着床、分娩的影响,PGF2α对母猪泌乳力及仔猪活力等方面的重要作用等,同时也综述了几种PGF2α及其类似物对母畜繁殖性能等方面的影响,旨在为PGF2α及其类似物的合理运用提供依据。

| Abstract: | Prostaglandin F2α (PGF2α) is a luteinolytic factor,which is widely used in estrus synchronization and induced parturition in sows.In recent years,new functions of PGF2α have been found one after another.As a pregnancy recognition signal of mammals,endogenous PGF2α can bind to PGF2α receptor (FP) in the fetus and endometrium,initiate downstream signal pathways,and play an important role in early embryonic development,implantation and pregnancy maintenance.Lack or insufficient synthesis will lead to pregnancy interruption or abortion.In view of the promoting effect of PGF2α on the reproduction activities of female animals,the veterinary drug center has developed a variety of PGF2α drugs,such as sodium chloroprostol,dinoprostaglandin F2α and so on,which are widely used to start delivery and promote estrus.According to the optical activity of sodium chloroprostol,it can be divided into D-type and L-type enantiomers,in which D-type structure is the main active component of sodium chloroprostol.Exogenous PGF2α drugs can not only induce simultaneous estrus and synchronous delivery of sows,promote postpartum health and increase the estrus rate of weaned sows,but also improve sow lactation ability and colostrum quality,improve piglet vitality and other production traits.This paper reviews the research progress of new functions of PGF2α at home and abroad in recent years,including the dual effects of PGF2α on periodic corpus luteum,the important effects of PGF2α on early embryo development,implantation and late pregnancy delivery,as well as the important effects of PGF2α on sow lactation and piglet vitality.It also summarizes the effects of several PGF2α and its analogues on reproductive performance of female animals.The purpose of this study is to provide theoretical basis for the rational use of PGF2α and its analogues. |
