2、,隨機(jī)分為6組,每組3個(gè)重復(fù),每個(gè)重復(fù)12只雞,11周齡時(shí)開(kāi)始進(jìn)入正式試驗(yàn)。分別飼喂添加蛋白質(zhì)螯合銅(以銅量計(jì))0ms/kg(I組)、6.5mS/kg(II組,對(duì)照組)、15ms/kg(Ⅲ組)、30mg/kg(1V組)、60ms/kg(V組)、125ms/kg(VI組)相同的基礎(chǔ)日糧,試驗(yàn)期為6周,測(cè)定雞的平均日增重、平均日采食量和新城疫抗體效價(jià)。結(jié)果表明:與對(duì)照組相比,Ⅲ組和Ⅳ組顯著提高育成蛋雞平均日增重、平均日采食量和新城疫抗體效價(jià)。添加15ms/kg和30ms/kg銅(以蛋白質(zhì)螯合銅的形式)可顯著
3、提高育成蛋雞的生產(chǎn)性能和免疫功能,15~30ms/kg銅(以蛋白質(zhì)螯合銅的形式)為育成蛋雞最適宜的添加范圍。關(guān)鍵詞:蛋白質(zhì)螫合銅;育成蛋雞;生產(chǎn)性能;新城疫抗體效價(jià)中圖分類號(hào):$816.72;$831.5文獻(xiàn)標(biāo)識(shí)碼:A文章編號(hào):1000—2286(2010)02—0206—04EfectofDietaryCopperLevelsonGrowthPerformanceandtheValueofSerumAntibodyaganistNewcastleDiseaseofGrowingLayersZHANGC
