摘　　要：发情控制是规模化猪场繁殖管理的一项重要技术手段,对发情母猪适时配种才能最大限度地发挥其繁殖性能,否则易造成母猪失配,导致非生产天数和饲养成本增加,严重影响猪场经济效益。因此,精准调控母猪的发情与排卵显得尤为重要。本文简要介绍了母猪发情与发情周期、影响母猪发情的因素,并阐述了母猪不同时期发情控制技术,为养猪生产中提高繁殖效率和经济效益提供参考。Oestrus control is an important technical tool for reproduction management in large-scale pig farms.Breeding sows in heat at the right time can maximize their fertility,otherwise it is easy to cause sow mismatch,which leads to the increase of non-productive days and feeding costs,and seriously affects the economic benefits of pig farms.Therefore,accurate regulation of sow oestrus and ovulation is particularly important.This paper briefly introduces sow oestrus and oestrus cycle,factors affecting sows in oestrus,and elaborates on oestrus control techniques in different periods of sows,aiming to provide reference for improving reproductive efficiency and economic efficiency in pig production.
