摘要
本试验选用192只1日龄AA肉公鸡,随机分成2个处理组,每个处理设6个重复,每个重复16只鸡,采用玉米-豆粕型饲粮,比较去皮豆粕和普通豆粕对肉鸡生产性能及营养素利用率影响的差异。结果表明:去皮豆粕对各阶段肉鸡的采食量、增重及料重比均无显著影响(P>0.05);去皮豆粕组饲粮粗蛋白质利用率比普通豆粕组提高8.80%(P<0.05),去皮豆粕组饲粮粗灰分、钙、磷利用率分别比对照组提高2.54%、4.63%、4.37%,但差异均不显著(P>0.05)。
One hundred and ninety two newly-hatched AA broilers,which were randomly allotted into 2 treatments with 6 replications of 16 birds,fed diets consisted of corn-dehulled soybean meal （DSBM） and corn-regular soybean meal （RSBM）,were introduced to compare their performance and nutrients availability.The results indicated that there were no significant differences of average daily gain（ADG）,average daily feed intake（ADF1） and feed conversion ratio（FCR） between DSBM and RSBM（P 〉 0.05）;availability of crude protein was increased by 8.80 % （P 〈 0.05） and availabilities of crude ash,calcium and phosphorus were increased by 2.54 %,4.63 % and 4.37 % （P 〉 0.05） respectively for broilers fed with DSBM.
