摘 要:试验选择了上天梯膨润土作为饲料添加剂 ,以肉鸡作为喂养对象 ,与不添加膨润土的试验对照组相比 ,饲喂添加有膨润土 1%、3%、5%的试验组 ,肉鸡的体重增加十分明显 ,增重分别为 1.7%、7.3%、和 11.7% ,肉料比由 2 .2 8分别下降到 2 .2 1,2 .0 3和 1.90。肉鸡在增重的同时 ,单位重量的耗料减少 ,经济效益分别提高了 5.1%、19.1%和 30 .9%。Bentonite from Shangtianti was taken as feedstuff additive that was mainly used to feed meat chicken. In contrast with the antitheses group in which the meat chicken were not fed bentonite additive, the experimental chicken had gained weight obviously. The experimental chicken which were fed 1%、3% and 5% bentonite had put on weight 1.7%、7.3% and 11.7%. The ratio of meat weight to feedstuff declined from 2.28 to 2.21,2.03 and 1.90, viz, consumption of feedstuff in unit weight decreasing. In the experiment, economic benefit increased 5.1%,19.1% and 30.9%.
