【摘要】 试验研究了在玉米-豆粕型日粮中添加脂肪酶对商品肉仔鸡生长性能、表观代谢能、血液生化指标和腹脂率等的影响。试验选用1日龄健康爱维因肉仔鸡240只,随机分为4个处理组,每个处理4个重复,每个重复15只鸡。试验期8周。整个饲养期分为3个阶段,0～3周为生长前期,4～6周为生长中期,7～8周为生长后期。结果表明,日粮中添加脂肪酶可显著提高肉鸡的日增重(P<0.05),降低料肉比(P<0.05),提高表观代谢能(P<0.05),降低血液中甘油三酯、总胆固醇、低密度脂蛋白(P<0.05),提高高密度脂蛋白含量(P<0.05),降低腹脂率(P<0.05)。更多还原

【Abstract】 This article studied the effect of lipase enzyme on growth performance,apparent metabolizable energy of nutrients,blood biochemical parameters and abdominal fat rate in corn-soybean meal-based diets of broilers.Experiment chose 240 one-day health AA broilers,randomly allocated to 4 groups with 4 replicates per group and 15 broilers per replicate with 8 weeks trial period.The feeding period was divided into three stages:0-3 week for the early growth stage,4-6 week for the medium growth stage and 7-8 week for the late growth stage.Experiment showed that lipase enzyme can improve ADG(P<0.05),reduce F/G(P<0.05) and improve apparent metabolizable energy(P<0.05) of nutrients of broilers,when it reduced triglyceride,total cholesterol,low-density lipoproteinand(P<0.05) and improved high-density lipoprotein(P<0.05),it reduced abdominal fat rate of broilers(P<0.05).更多还原
