不同日粮对生长蛋鸡生产性能及营养代谢的影响

The Effects of Different Diets on Growing and Nutrient Metabolism of Chick

1500只1日龄京白雏鸡被随机分为5组,分别饲喂Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ种日粮,测定不同日粮对生长期生产性能及营养代谢的影响。结果：Ⅰ组20周龄末重最高,极显著(P＜0.01)高于Ⅴ组,显著(P＜0.05)高于Ⅱ、Ⅲ、Ⅳ组。

One thousand five hundred me-day-old Beijing White chicks were randomly divided to 5 groups and fed 5different diets, respectively, to determine the effects of diets on growing and nutrient metabolism. The results indicated that the average body weight at 20 weeks of Group Ⅰ was significantly higher （P〈0.01） than that of GroupV, and was higher （P〈0.05） than those of GroupⅡ ,Ⅲ, Ⅳ.
