Effects of Different Forms of High Copper on the Growth Performance of Pig at Different Growth Stages
选用50头“杜长大”断奶猪,分成5组(每组2个重复),分别按每kg基础日粮添加50 mg硫酸铜(Ⅰ组)、150 mg硫酸铜(Ⅱ组)、250 mg硫酸铜(Ⅲ组)、150mg蛋氨酸铜(Ⅳ组)、250mg蛋氨酸铜(V组),分两阶段进行饲养试验.第一阶段从正试期到第11周,每4周称量1次.第二阶段从第12周开始,将第Ⅱ-V组每组各自重新分出一组,组成加Ⅱ组、加Ⅲ组、加Ⅳ组、加Ⅴ组,每组各4头猪,喂给与第Ⅰ组相同的日粮,原第Ⅱ-Ⅴ组继续喂给与第一阶段相同日…查看全部>>
Fifty weanling pigs (Duroc× landrace× Yorkshire) were randomly assigned into five groups,10 for each,and different forms and levels of copper were added to their diet, 50 mg CuSO4(Group Ⅰ ) and 150 mg(Group Ⅱ ),250 mg( Group Ⅲ) and 150 mg Cu-Met (Group Ⅳ) and 250 mg(Group Ⅴ ).This experiment was carried out in two phases.The first phase was from the beginning to the eleventh week, and bodies were weighed every four weeks.The second phase was from the …查看全部>>
