不同浓度活菌酶蛋白血粉饲养育肥猪的对比试验

Comparative Feeding Trial of Pig Finishers Fed on the Active Enzymatic Blood Meals at Different Levels

在测定活菌酶蛋白血粉养分及氨基酸组成的基础上 ,以玉米—豆粕型日粮为对照组 ,将活菌酶蛋白血粉按 2 .5 %、5 %、10 %的配比分为 3个试验组进行了试验。选用 4 0头仔猪进行饲养对比试验。根据各组的增重情况进行统计分析 ,试验结果表明饲料中添加 2 .5 %～ 5 %活菌酶蛋白血粉有利于育肥猪的生长。

On the basis of determining the nutrients and the component amino acids of active enzymatic blood meals, and taking normal corn-soybean meal diet as a control, a comparative trial was done to feed 40 pig finishers on active enzymatic blood meals with added proportions of 2.5%, 5% and 10% respectively. The results showed that the addition of 2.5%～5% active enzymatic blood meals was helpful to the growth of pigs.
