菜籽粕替代豆粕饲喂产蛋鸡试验

Feeding Experiment of Substituting Soybean Meal for Rape Seed Meal in Diet of Layers

用4%、8%和10%的菜籽粕替代豆粕饲喂黄金褐蛋鸡,结果表明,对产蛋鸡的生产性能没有显著影响(P>0.05),对饲料中粗蛋白质的表观利用率也没有显著影响(P>0.05),随着菜籽粕的增加,饲料中粗蛋白质的表观利用率有下降的趋势。

Three diets in which 4%,8% and 10% rape seed meal substituted for soybean meal respectively were fed to Gold-brown layer,the results showed that there was no significant difference in performance of layers in three groups（P0.05）,and there was no significant influence on apparent availability of CP（P0.05）,with increasing the amount of rape seed meal in diet,apparent availability of CP in diet trended to decrease..
