夏季高温季节农村规模化猪场母猪饲养管理技术

Feeding and Management Technology of Sows in Large-Scale Rural Pig Farms in High-Temperature Summer Season

夏季高温季节热应激因素是困扰生猪养殖产业健康发展,影响母猪繁殖机能,导致免疫功能下降的主要因素。由于母猪的体表散热功能较差,进入夏季后外界温度逐渐升高,母猪对热应激十分敏感,一旦体内的温度超过临界承受能力,会造成严重的热应激反应,甚至造成中暑死亡。该文主要论述夏季高温季节农村规模化养猪场母猪养殖管理技术要点。

Heat stress is the main factor that perplexes the healthy development of pig breeding industry,affects the reproductive function of sows,and leads to the decline of immune function.Sows are very sensitive to heat stress because of the poor heat dissipation of the body surface and the gradual increase of the external temperature in summer.Once the temperature in the body exceeds the critical bearing capacity,a serious heat stress reaction will occur,and even death from heatstroke.This paper mainly discusses the key techniques of sows breeding management in large-scale pig farms in the high temperature season in summer.
