每年的春季和秋季都是雞舍或者雞群通風管理的過渡性季節
，很多地方白天的氣溫可能高達27-28度或者更高，然而到了夜晚溫度經常會下降到10度以下
，這種15-20度du以yi上shang的de溫wen度du波bo動dong常chang常chang使shi家jia禽qin管guan理li人ren員yuan感gan到dao這zhe樣yang的de季ji節jie條tiao件jian要yao想xiang管guan理li好hao雞ji舍she通tong風feng確que實shi比bi較jiao棘ji手shou。而er且qie，這zhe樣yang的de晝zhou夜ye溫wen差cha變bian化hua也ye會hui在zai其qi它ta季ji節jie經jing常chang出chu現xian，特te別bie是shi在zai南nan方fang某mou些xie地di區qu冬dong季ji也ye經jing常chang出chu現xian這zhe種zhong現xian象xiang。

　　通風的目標是保持雞舍溫度處於合理範圍內，充分發揮雞群的生產性能。下例圖表說明了商品肉雞獲得最佳生產性能（料肉比和體重）duiwendudeyaoqiu。congxiatukeyikanchu

　　解(jie)決(jue)問(wen)題(ti)的(de)辦(ban)法(fa)是(shi)改(gai)變(bian)通(tong)風(feng)方(fang)式(shi)，通(tong)過(guo)安(an)裝(zhuang)在(zai)雞(ji)舍(she)末(mo)端(duan)的(de)排(pai)風(feng)扇(shan)進(jin)行(xing)排(pai)風(feng)，關(guan)閉(bi)雞(ji)舍(she)前(qian)端(duan)為(wei)縱(zong)向(xiang)通(tong)風(feng)而(er)設(she)計(ji)的(de)進(jin)風(feng)口(kou)，並(bing)使(shi)空(kong)氣(qi)從(cong)雞(ji)舍(she)側(ce)牆(qiang)上(shang)方(fang)的(de)進(jin)風(feng)口(kou)進(jin)入(ru)雞(ji)舍(she)，這(zhe)樣(yang)的(de)話(hua)

　　這種相對較新的通風方法就是所謂的“過渡期通風”，如ru下xia圖tu，其qi優you點dian是shi能neng在zai溫wen度du上shang下xia波bo動dong比bi較jiao大da或huo內nei部bu環huan境jing變bian化hua較jiao大da的de情qing況kuang下xia進jin行xing良liang好hao的de通tong風feng。進jin行xing這zhe樣yang的de通tong風feng時shi，我wo們men可ke以yi關guan閉bi雞ji舍she前qian端duan為wei縱zong向xiang通tong風feng而er設she計ji的de進jin風feng口kou

，為了能達到最有效的控製，最好采用自動控製係統。
