冬季保(bao)持舍內溫度適宜，同時要做(zuo)好(hao)通風換(huan)氣工作，否則(ze)會嚴重影響肉鴨的生長發(fa)育(yu)。
通(tong)風(feng)(feng)(feng)換氣(qi)(qi)應(ying)掌握的原則(ze)是：在能(neng)保證溫度的前(qian)提(ti)下，盡量通(tong)風(feng)(feng)(feng)：早晚天(tian)氣(qi)(qi)冷時(shi)(shi)小敞通(tong)風(feng)(feng)(feng)口或不開，中午(wu)時(shi)(shi)大(da)敞；有風(feng)(feng)(feng)時(shi)(shi)小敞，無風(feng)(feng)(feng)時(shi)(shi)大(da)敞，要(yao)循序漸進(jin)，有個過程，不能(neng)說通(tong)風(feng)(feng)(feng)時(shi)(shi)所有通(tong)風(feng)(feng)(feng)口一(yi)下全部打開，以致造(zao)成棚內環(huan)境變化(hua)巨大(da)。當進(jin)入鴨舍(she)(she)感覺(jue)氣(qi)(qi)味(wei)刺(ci)鼻(bi)時(shi)(shi)，敞開通(tong)風(feng)(feng)(feng)口，排出舍(she)(she)內有害氣(qi)(qi)體，讓新鮮空氣(qi)(qi)流入舍(she)(she)內，要(yao)注意通(tong)風(feng)(feng)(feng)換氣(qi)(qi)前(qian)要(yao)將舍(she)(she)溫提(ti)高2-3℃，通(tong)風(feng)(feng)(feng)換氣(qi)(qi)時(shi)(shi)仍要(yao)生爐子。飼養前(qian)期以保溫為主(zhu)(zhu)，兼(jian)顧通(tong)風(feng)(feng)(feng)；飼養后期以通(tong)風(feng)(feng)(feng)換氣(qi)(qi)為主(zhu)(zhu)，兼(jian)顧保溫。
具體(ti)做法要(yao)根據(ju)風(feng)(feng)力大小，天(tian)(tian)(tian)氣(qi)(qi)(qi)陰晴，氣(qi)(qi)(qi)溫(wen)(wen)高低，日齡與健(jian)康狀況確定開啟通(tong)(tong)風(feng)(feng)口(kou)的(de)次數，大小和方向。一般情況下，根據(ju)日齡及健(jian)康情況，鴨(ya)(ya)舍南(nan)(nan)(nan)北面夜(ye)間封(feng)閉，白天(tian)(tian)(tian)無大風(feng)(feng)天(tian)(tian)(tian)氣(qi)(qi)(qi)，可(ke)適(shi)當(dang)打(da)開通(tong)(tong)風(feng)(feng)口(kou)用以通(tong)(tong)風(feng)(feng)換氣(qi)(qi)(qi)。隨著晝(zhou)夜(ye)溫(wen)(wen)差變小，無大風(feng)(feng)天(tian)(tian)(tian)氣(qi)(qi)(qi)南(nan)(nan)(nan)北面可(ke)部(bu)分或全(quan)部(bu)打(da)開。但通(tong)(tong)風(feng)(feng)口(kou)要(yao)由上往下放大，這樣(yang)能保證(zheng)空氣(qi)(qi)(qi)新鮮，同時有一個良好(hao)的(de)溫(wen)(wen)度(du)環境。鴨(ya)(ya)舍南(nan)(nan)(nan)北面的(de)通(tong)(tong)風(feng)(feng)控(kong)制，可(ke)由掛塑料(liao)布(bu)的(de)鐵絲定位出風(feng)(feng)口(kou)的(de)大小。這樣(yang)“拉鐵絲上圍子”的(de)做法也解決了保溫(wen)(wen)與通(tong)(tong)風(feng)(feng)換氣(qi)(qi)(qi)二(er)者(zhe)之間的(de)矛盾(dun)。
