摘要
膨润土是一种含有畜禽所需的多种微量及常量元素的天然矿物。用膨润土配制的猪用添加剂——“得灵”I.I号,经过2年多共7批次总计449头猪的饲养试验表明,饲料利用率比所采用的几个对比添加剂及浓缩料提高1%~25%,饲料报酬为2.86~3.20:1,每增重1kg活重降低成本0.1~1.0元。
Bentonit is a natural mineral which contains many kinds of trace elementand macroelement essential for the animal. It was demonstrated from the comparisionsamong the bentonite feed additives and the comparing feed additives, if the bentonite feed ad-ditives used, the feed conversion efficiency was raised about 1%~25%, the ratio of feed tomeat was 2.86~3.20:1, and the cost of gaining one kilogrammes weight was reduced about0.1 to 1.0 to Chinese yuan. The experiments were conducted for more than two years and thetest pigs total to 449 heads
