一、改善舍內通風 zhuzaieliedekongqihuanjingzhongduoshuhuifashengfeiyan。huwaisiyangdezhujihubufashengfeiyan，zheshiyinweidaliangdexinxiankongqiqilezuoyong。dongchunjijieyaofangzhizeifeng

、門沒關好、門窗破了或者牆上和簾子上有洞，風速都會增強，這樣豬就會發生呼吸係統疾病。

二
、控製舍內溫度 理想的溫度條件下，豬隻任何時間都會感到舒適。溫度過低會造成應激，降低豬的免疫力，增加發病率。豬的臨界溫度初生仔豬32~35℃，4~10公斤仔豬29~24℃，斷乳3~4周後的培育種豬(育肥豬)25~15℃

，成年豬下限臨界溫度12℃。生產中應保證新斷奶仔豬舍足夠溫暖
，必要情況下進豬前應提前24~49小時為豬舍增溫。豬對溫度的需求是隨著年齡的增長而降低
，養殖戶要製定逐漸降溫的計劃
，並按照嚴格規定進行實施。

三、搞好濕度調節 豬對舍內的濕度也有一定的要求，相對濕度低於50%就太幹，高於75%就太濕。如果舍內濕度太低

，極易引起豬隻發生呼吸道疾病。潮濕空氣的導熱性為幹燥空氣的10倍bei
，冬dong季ji如ru果guo舍she內nei濕shi度du過guo高gao，就jiu會hui使shi豬zhu體ti散san發fa的de熱re量liang增zeng加jia，使shi豬zhu隻zhi更geng加jia寒han冷leng。生sheng產chan中zhong可ke采cai用yong加jia強qiang通tong風feng和he在zai室shi內nei放fang生sheng石shi灰hui塊kuai等deng辦ban法fa降jiang低di舍she內nei濕shi度du。

四
、合理的飼養密度 飼養密度是否合理不僅與豬的發育狀況有關，還與豬的肺炎有密切的關係；midudegainianyiqihoubutong，dongjisuikeshaodayixie，danmeigequansheneiyingyouzongmianjisanfenzhierdeganzaodimianyongyuzhuzhitangwohexiuxi。wulunshishuinidimianhaishiluoludedimian

五、科學的飲水觀念 一yi是shi要yao注zhu意yi飲yin水shui消xiao毒du
