复合蛋白饲料替代豆粕饲喂蛋鸡的效果及经济效益分析

试验选用30周龄产蛋高峰期海蓝褐商品蛋鸡192只,随机分成4个处理,每个处理设3个重复,每个重复16只鸡。以玉米蛋白粉、棉粕、DDGS和菜粕为主要原料配制成复合蛋白饲料完全替代基础日粮中的豆粕。结果表明:在对照组、试验1组、试验2组和试验3组等四个处理之间比较生产性能差异不显著(P>0.05),蛋品质测定指标差异不显著(P>0.05),产蛋鸡饲料中常规营养成分消化率差异不显著(P>0.05)。

Effect and Analysis of Economic Benefits of Compound Protein Feed Substitution for Soybean Meal in Laying Hens

192 thirty weeks hailanhe commercial laying hens producing eggs in high peaks were divided into four treatments randomly, with three replications per treatment and sixteen laying hens each replication. The compound protein feed which was compounded by corn gluten meal, cottonseed meal, DDGS and rapeseed meal as the main raw materials substituted for the soybean meal of the basal diet completely. The results showed as follows among the four treatments of the control group, trial 1, trial 2 and trial 3, the differences of the productive performances, the egg quality determination targets and the digesting rates of routine nutritional elements in the feed were not significant (P > 0.05).
