摘要/Abstract

摘要： 胎衣不下是奶牛产后常见繁殖疾病,并会导致继发疾病,给牧场带来巨大的经济损失。关于奶牛胎衣不下发病机制尚未完全揭示,胎盘结构特殊性和胎衣排出复杂过程导致奶牛胎衣不下时常发生。本文从奶牛生理结构特点、围产期代谢特点和生产过程免疫抑制等角度对奶牛胎衣不下的病因以及防控措施进行了阐述,并系统地分析因胎衣不下造成的牧场经济损失,旨在为预防及治疗奶牛胎衣不下提供参考,提高牧场盈利能力。

Abstract: Retention of fetal membranes （Retained Fetal Membranes,RFM）in dairy cow can lead to adverse health effects that ultimately affect ranch revenue. While the mechanisms behind of factors that caused RFM are not completely understood,the knowledge of the placental anatomy and physiology of placenta expulsion is helpful to manage this disease. This review discussed the physiology of placenta,the metabolism characteristics of transition period and the postpartum immunosuppression to better understand the process of detachment and etiology,pathogenesis and prevention. To uncover the cost of RFM,the study also analyzed various parameters resulting in economic losses in dairy herds.

Key words: dairy cow, retained fetal membranes（RFM）, transition period metabolism, immunosuppression
