本试验旨在探讨肉鸡饲料中添加蛋白铜、蛋白铁、蛋白锌、蛋白锰等螯合微量元素对白羽肉鸡生长性能和微量元素排放的影响。试验选择22日龄的艾维茵肉鸡900只,随机分为3组(A,B,C),每组3个重复,每个重复100只鸡。A组为正常对照组,饲喂添加1kg/吨无机微量元素日粮,B、C组为试验组,B组饲喂添加200g/吨有机惠并减少10%维生素组的日粮,C组饲喂添加100g/吨有机惠的日粮。各组日粮均为粉料。试验结果表明:各组间的平均日增重、平均日采食量和料肉比差异均不显著(P>0.05);其中,B组的采食量和日增重分别比对照组提高2.7%和2.5%,B组和C组的死淘率分别较对照组降低9.26%和23.6%,但无显著差异(P>0.05)。添加10...

The experiment studied the comparison of different composition of trace element forms on productivity and fecal trace elements contents.Nine hundred 22-day-old Avian broiler were chosen and randomly allocated into 3 groups(A,B,C)with 3 replicates per group and 100 Avian broiler per replicate in a complete randomized design.The three treatments were control group,1kg/t inorganic trace mineral group+100%compound vitamin group(A),200g/t organic trace mineral+90%compound vitamin group(B)and 100g/t organic trace mineral+100%com-pound vitamin group(C...
