冬(dong)季(ji)必(bi)須保持舍(she)內溫度適宜，同(tong)時(shi)要做好(hao)通風換氣工(gong)作，否則會嚴(yan)重影響肉鴨(ya)的(de)生長發育。
通(tong)(tong)(tong)風(feng)(feng)(feng)換氣(qi)應掌握的(de)(de)原則(ze)是：在能保證溫度(du)的(de)(de)前(qian)提下(xia)，盡量通(tong)(tong)(tong)風(feng)(feng)(feng)：早晚(wan)天氣(qi)冷(leng)時(shi)(shi)(shi)小(xiao)(xiao)敞(chang)(chang)通(tong)(tong)(tong)風(feng)(feng)(feng)口或不(bu)(bu)開，中午(wu)時(shi)(shi)(shi)大敞(chang)(chang)；有(you)風(feng)(feng)(feng)時(shi)(shi)(shi)小(xiao)(xiao)敞(chang)(chang)，無風(feng)(feng)(feng)時(shi)(shi)(shi)大敞(chang)(chang)，要循序漸進，有(you)個過程，不(bu)(bu)能說通(tong)(tong)(tong)風(feng)(feng)(feng)時(shi)(shi)(shi)所有(you)通(tong)(tong)(tong)風(feng)(feng)(feng)口一(yi)下(xia)全部打開，以(yi)致(zhi)造成棚內(nei)(nei)環境變化巨大。當進入(ru)鴨舍(she)(she)感覺(jue)氣(qi)味刺鼻(bi)時(shi)(shi)(shi)，必須敞(chang)(chang)開通(tong)(tong)(tong)風(feng)(feng)(feng)口，排出舍(she)(she)內(nei)(nei)有(you)害(hai)氣(qi)體，讓新(xin)鮮空(kong)氣(qi)流入(ru)舍(she)(she)內(nei)(nei)，要注意通(tong)(tong)(tong)風(feng)(feng)(feng)換氣(qi)前(qian)要將(jiang)舍(she)(she)溫提高2-3℃，通(tong)(tong)(tong)風(feng)(feng)(feng)換氣(qi)時(shi)(shi)(shi)仍要生爐(lu)子(zi)。飼養(yang)前(qian)期(qi)以(yi)保溫為主(zhu)，兼顧通(tong)(tong)(tong)風(feng)(feng)(feng)；飼養(yang)后(hou)期(qi)以(yi)通(tong)(tong)(tong)風(feng)(feng)(feng)換氣(qi)為主(zhu)，兼顧保溫。
具(ju)體(ti)做法要根(gen)據(ju)風(feng)(feng)力大小(xiao)，天氣陰晴，氣溫(wen)(wen)高(gao)低(di)，日(ri)齡(ling)(ling)與健康(kang)狀況確定(ding)開啟通(tong)(tong)(tong)風(feng)(feng)口(kou)的(de)(de)次數，大小(xiao)和方向(xiang)。一(yi)般情(qing)(qing)況下，根(gen)據(ju)日(ri)齡(ling)(ling)及健康(kang)情(qing)(qing)況，鴨舍南北(bei)(bei)面夜(ye)間封閉(bi)，白天無(wu)大風(feng)(feng)天氣，可適當打(da)(da)開通(tong)(tong)(tong)風(feng)(feng)口(kou)用以通(tong)(tong)(tong)風(feng)(feng)換氣。隨(sui)著晝(zhou)夜(ye)溫(wen)(wen)差變小(xiao)，無(wu)大風(feng)(feng)天氣南北(bei)(bei)面可部(bu)分或全(quan)部(bu)打(da)(da)開。但通(tong)(tong)(tong)風(feng)(feng)口(kou)要由上往下放大，這(zhe)樣能保證(zheng)空氣新鮮，同時(shi)有一(yi)個(ge)良好(hao)的(de)(de)溫(wen)(wen)度環境(jing)。鴨舍南北(bei)(bei)面的(de)(de)通(tong)(tong)(tong)風(feng)(feng)控制，可由掛(gua)塑料布的(de)(de)鐵絲定(ding)位出風(feng)(feng)口(kou)的(de)(de)大小(xiao)。這(zhe)樣“拉(la)鐵絲上圍子”的(de)(de)做法也解決了保溫(wen)(wen)與通(tong)(tong)(tong)風(feng)(feng)換氣二者之間的(de)(de)矛盾。
