夏季规模化蛋鸡场日常管理措施

Daily Management Measures of Large-scale Layer Farm in Summer

鸡无汗腺,散热方式主要以呼吸散热为主,饮水排泄为辅,鸡群热应激会表现出大量饮水、食欲下降、体温升高等现象,进而影响鸡的正常生产性能,造成饲料转化率及蛋鸡产蛋率降低、蛋重减轻、破蛋率、死淘率增加等情况,严重时会出现鸡群大面积死亡。该文主要论述夏季规模化蛋鸡场日常管理措施。

Chickens have no sweat glands,and the heat dissipation method is mainly respiratory heat dissipation,supplemented by drinking water excretion.The heat stress of chickens will show a lot of drinking water,decrease of appetite,increase of body temperature and so on,which will affect the normal production performance of chickens,as a result,the feed conversion rate and the laying rate of layers decrease,the weight of eggs decreases,the rate of broken eggs increases,and the mortality rate increases.This paper mainly discusses the daily management measures of large-scale laying hen farm in summer.
