高產蛋鴨的辨別方法

1、高(gao)產蛋鴨(ya)眼(yan)大凸(tu)出而(er)有神，頭稍小，頸細長(chang)，體長(chang)、背(bei)寬(kuan)、胸(xiong)闊深、發育飽(bao)滿(man)均衡、行動(dong)敏捷。用(yong)手提鴨(ya)頸時，兩腳向(xiang)下(xia)伸直，不動(dong)彈。低(di)產鴨(ya)眼(yan)小不凸(tu)出且(qie)無神，頭大頸粗(cu)、體短，背(bei)、胸(xiong)較窄、行動(dong)遲緩。用(yong)手提鴨(ya)頸時，雙(shuang)腳屈起。

2、高產(chan)鴨(ya)(ya)(ya)飽(bao)食(shi)(shi)后，頸段食(shi)(shi)管膨大下垂。這表示容有較(jiao)多的食(shi)(shi)料，營(ying)養物質(zhi)充足，能(neng)高產(chan)，反之(zhi)是(shi)(shi)(shi)低產(chan)的表現。不(bu)論是(shi)(shi)(shi)新(xin)鴨(ya)(ya)(ya)還(huan)是(shi)(shi)(shi)兩年(nian)生以上的老鴨(ya)(ya)(ya)，淄(zi)博紅嘴鴨(ya)(ya)(ya)苗，在開(kai)產(chan)之(zhi)前，羽(yu)毛都(dou)豐(feng)厚，緊(jin)密細致(zhi)。開(kai)產(chan)后高產(chan)鴨(ya)(ya)(ya)體(ti)內吸收營(ying)養大部分用來產(chan)蛋(dan)，很少用于長身體(ti)，其羽(yu)毛光(guang)澤逐漸減退(tui)，變得零(ling)亂而無光(guang)。如果它的頭頂、頸部、脊背的羽(yu)毛變得稀疏說明它勤(qin)與(yu)公鴨(ya)(ya)(ya)交配，也是(shi)(shi)(shi)高產(chan)的象征(zheng)。

肉鴨(ya)，鵝的飼料按(an)形(xing)狀分有粉(fen)料、顆(ke)(ke)粒料和(he)顆(ke)(ke)粒料等。

粉(fen)料(liao)(liao)易生(sheng)產(chan)(chan)而且成(cheng)本(ben)較(jiao)(jiao)低(di)。具有加(jia)工簡單(dan)、營(ying)養(yang)、費用(yong)(yong)低(di)、加(jia)便、剩料(liao)(liao)不(bu)易霉變(bian)等優點，是(shi)(shi)(shi)中(zhong)小(xiao)散養(yang)戶(hu)使(shi)(shi)用(yong)(yong)較(jiao)(jiao)多的料(liao)(liao)。 缺(que)點是(shi)(shi)(shi)粉(fen)料(liao)(liao)易產(chan)(chan)生(sheng)粉(fen)塵。顆粒(li)料(liao)(liao)是(shi)(shi)(shi)全價料(liao)(liao)加(jia)上黏合劑調制(zhi)(zhi)后壓制(zhi)(zhi)而成(cheng)。顆粒(li)大小(xiao)可(ke)調，以 適(shi)(shi)應(ying)不(bu)同生(sheng)長階段(duan)肉(rou)鴨(ya)，鵝(e)的營(ying)養(yang)需要(yao)。確保(bao)肉(rou)鴨(ya)，鵝(e)在(zai)(zai)食(shi)(shi)入(ru)飼(si)料(liao)(liao)時，各種養(yang) 分都被均衡地(di)食(shi)(shi)入(ru)。顆粒(li)料(liao)(liao)還可(ke)提高適(shi)(shi)口性，使(shi)(shi)肉(rou)鴨(ya)，鵝(e)采食(shi)(shi)量增大，更(geng) 容易獲得肉(rou)鴨(ya)，鵝(e)生(sheng)產(chan)(chan)性能所要(yao)求攝入(ru)的營(ying)養(yang)成(cheng)分;使(shi)(shi)肉(rou)鴨(ya)，紅嘴鴨(ya)苗多少錢一只，鵝(e)只無法(fa)挑食(shi)(shi)， 減少了飼(si)料(liao)(liao)的浪費。在(zai)(zai)制(zhi)(zhi)粒(li)過程(cheng)(cheng)中(zhong)由于(yu)要(yao)求溫度較(jiao)(jiao)高，對(dui)沙門(men)菌及其 他(ta)有害(hai)菌也是(shi)(shi)(shi)一個滅菌過程(cheng)(cheng)。
