用复合蛋白素替代豆饼饲喂黄牛的效果研究

Effect of feeding yellow cattle with compound albumnate instead of soybean meal

用复合蛋白素替代精料中 1 0 0 %的豆饼 (试验Ⅰ组 )和 50 %的豆饼 (试验Ⅱ组 )饲喂黄牛。结果表明 :精料成本分别降低了 1 3 .45 %和 6 .76 % ;试验I组平均日增重比对照组提高了 62g(P <0 .0 5) ,试验Ⅱ组平均日增重未得到显著提高 (P >0 .0 5) ;试验Ⅰ组和试验Ⅱ组经济效益 (日均粗收益 )分别比对照组提高 76 .1 9%和 40 .2 9%。

Compound albumnate were utilized to substitute 100%(experiment Ⅰ) and 50% (experiment Ⅱ) soybean meal in concentrate of yellow cattle.The results showed that concentrate cost reduced by 13.45% and 6.76% respectively,as compared with that of the control;while the average daily gain of the experiment I was 62 g higher than that of the control(P<0.05);the (crude)economic effciency of experiment groups were 76.19% and 40.29% higher than that of the control group.
