本试验旨在研究过氧化氢酶( CAT)对黄羽肉鸡生长性能、肠道形态以及抗氧化能力的影响。选用健康的1日龄雄性黄羽肉鸡360只,随机分为4个组,即试验1组、试验2组、试验3组和试验4组,每个组6个重复,每个重复15只鸡。试验1组饲喂基础饲粮,试验2组饲喂基础饲粮+ 100 U / kg CAT,试验3组饲喂基础饲粮+ 150 U / kg CAT,试验4组饲喂基础饲粮+ 200 U / kg CAT,其中CAT活性为5 000 U / g;试验期分为前期(1 ~ 21日龄)和后期( 22 ~ 45日龄) 。结果表明:1)与试验1组相比,1 ~ 21日龄试验4组、22 ~ 45日龄试验3组和试验4组、1 ~ 45日龄试验3组和试验4组体增重显著提高( P

The experiment was conducted to study the effects of catalase (CAT) on growth performance, intestinal morphology and antioxidant capacity in yellow broilers. A total of 360 healthy and one-day-old male yellow broilers were selected and randomly allocated to 4 groups with 6 replicates per group and 15 chickens per replicate. The chickens in test group 1 were fed a basal diet, those in test group 2 were fed the basal diet+ 100 U / kg CAT, those in test group 3 were fed the basal diet+150 U / kg CAT, those in test group 4 were fed the basal diet+200 U / kg CAT, respectively. The experimental peri...
