Abstract

Development of bovine estrus synchronization protocols started in the 1970’s. The aim of these protocols has changed progressively from synchronizing estrus to synchronizing ovulation with main goal of performing insemination without heat detection (Timed artificial insemination). The present paper discusses the physiology behind development of these synchronization protocols and reviews of the main protocols used nowadays in dairy herd reproductive management.

奶牛发情与排卵的同步
牛发情期同步协议的开发始于20世纪70年代。这些方案的目的已经从同步发情逐渐转变为同步排卵,主要目标是在没有热量检测的情况下进行人工授精(定时人工授精)。本文讨论了这些同步协议发展背后的生理学,并回顾了目前在奶牛群繁殖管理中使用的主要协议。
