低能日粮添加脂肪酶对黄羽肉鸡生长性能的影响

Effects of supplementation lipase in low energy diet on growth performance of yellow broiler

研究低能日粮添加脂肪酶对黄羽肉鸡生长性能的影响。将1350只1日龄黄羽肉鸡随机分为3个组(正对照、负对照、负对照+脂肪酶),每组6个重复,每个重复75只鸡,进行为期63 d的试验。研究结果表明,在低能日粮(日粮正常能量水平下调0.29 MJ/kg)基础上添加脂肪酶能显著(P<0.01)改善肉鸡的耗料增重比,日均增重无显著(P>0.15)差异。说明低能日粮添加脂肪酶对于改善肉鸡的生长性能有一定效果。

The purpose of this experiment was to study the effect of lipase on the growth performance of yellow broiler.In this experiment,13501 day old yellow chicks were randomly divided into three groups(positive control,negative control,negative control+lipase).Each group consisted of six replicates,75 broilers per replicate.The experiment lasted 63 days.On the basis of low-energy diet(the normal energy level of the diet was reduced by 0.29 MJ/kg),adding lipase could significantly(P<0.01)improves the feed consumption and weight gain ratio of broilers,and there was no significant difference in daily average weight gain(P>0.15).The results showed that the addition of lipase to low energy diet could improve the growth performance of yellow broiler.
