冬(dong)季必須保持舍(she)內(nei)溫度適(shi)宜，同時要做好(hao)通風換氣工作，否則會(hui)嚴重影響肉(rou)鴨的生長發育。
通(tong)風(feng)(feng)(feng)(feng)(feng)換(huan)氣(qi)應掌握的原則是：在能(neng)保證溫(wen)度的前提(ti)下，盡(jin)量通(tong)風(feng)(feng)(feng)(feng)(feng)：早(zao)晚天(tian)氣(qi)冷時(shi)(shi)(shi)小敞通(tong)風(feng)(feng)(feng)(feng)(feng)口(kou)或不(bu)開，中(zhong)午時(shi)(shi)(shi)大敞；有風(feng)(feng)(feng)(feng)(feng)時(shi)(shi)(shi)小敞，無風(feng)(feng)(feng)(feng)(feng)時(shi)(shi)(shi)大敞，要循序漸進(jin)，有個(ge)過程，不(bu)能(neng)說(shuo)通(tong)風(feng)(feng)(feng)(feng)(feng)時(shi)(shi)(shi)所有通(tong)風(feng)(feng)(feng)(feng)(feng)口(kou)一下全部打開，以(yi)致(zhi)造成棚內環境變化巨大。當進(jin)入(ru)鴨舍感覺氣(qi)味刺鼻時(shi)(shi)(shi)，必須敞開通(tong)風(feng)(feng)(feng)(feng)(feng)口(kou)，排(pai)出舍內有害(hai)氣(qi)體，讓新鮮空氣(qi)流入(ru)舍內，要注意通(tong)風(feng)(feng)(feng)(feng)(feng)換(huan)氣(qi)前要將舍溫(wen)提(ti)高(gao)2-3℃，通(tong)風(feng)(feng)(feng)(feng)(feng)換(huan)氣(qi)時(shi)(shi)(shi)仍要生(sheng)爐子。飼(si)養前期以(yi)保溫(wen)為(wei)主(zhu)，兼顧(gu)通(tong)風(feng)(feng)(feng)(feng)(feng)；飼(si)養后期以(yi)通(tong)風(feng)(feng)(feng)(feng)(feng)換(huan)氣(qi)為(wei)主(zhu)，兼顧(gu)保溫(wen)。
具體做法要根據風(feng)(feng)(feng)(feng)力大(da)小，天氣(qi)陰晴(qing)，氣(qi)溫高低，日(ri)(ri)齡與(yu)健康狀況確定(ding)開(kai)啟(qi)通(tong)風(feng)(feng)(feng)(feng)口的次數，大(da)小和(he)方向。一般情況下(xia)，根據日(ri)(ri)齡及健康情況，鴨(ya)舍(she)南北面(mian)夜間封閉，白天無(wu)大(da)風(feng)(feng)(feng)(feng)天氣(qi)，可適當打開(kai)通(tong)風(feng)(feng)(feng)(feng)口用以通(tong)風(feng)(feng)(feng)(feng)換氣(qi)。隨著晝(zhou)夜溫差(cha)變小，無(wu)大(da)風(feng)(feng)(feng)(feng)天氣(qi)南北面(mian)可部(bu)分或全部(bu)打開(kai)。但(dan)通(tong)風(feng)(feng)(feng)(feng)口要由上往下(xia)放大(da)，這(zhe)樣能保證空氣(qi)新鮮，同時有(you)一個良(liang)好(hao)的溫度環境。鴨(ya)舍(she)南北面(mian)的通(tong)風(feng)(feng)(feng)(feng)控(kong)制，可由掛塑料布的鐵(tie)絲(si)定(ding)位出風(feng)(feng)(feng)(feng)口的大(da)小。這(zhe)樣“拉(la)鐵(tie)絲(si)上圍子”的做法也解決了(le)保溫與(yu)通(tong)風(feng)(feng)(feng)(feng)換氣(qi)二者之(zhi)間的矛(mao)盾(dun)。
