母猪分娩控制技术研究进展

Research Progress on Control Technology in Sow Parturition

分娩控制是提高母猪繁殖效率和猪场生产管理水平的一项重要繁殖调控措施,利用该技术可实现对母猪分娩时间的预测和同期化处理,既便于围产期管理,又有利于降低母猪产后乏情和新生仔猪死亡。随着母猪批次化生产在我国的推广应用,分娩控制技术的应用越来越广泛。本文综述了母猪分娩控制的原理、影响母猪分娩控制的因素以及母猪分娩控制的外源激素应用现状,旨在为养猪业转型升级、提质增效奠定基础。

Parturition control is an important reproductive control measure to improve the reproductive efficiency of sows and production management on farms.It can be used to predict and control the time of farrowing of sows,which not only facilitates periparturient management,but also helps to reduce post-parturient lack of estrus and newborn piglet mortality.This article reviews the principle of sow farrowing control,the factors affecting sow farrowing control and the current situation of exogenous hormone application for sow farrowing control,aiming to lay the foundation for transformation and upgrading of the pig industry and increase the quality and efficiency.
