不同牧草饲喂肉羊的试验

Experiment on Feeding Mutton Sheep with Different Herbage

为探讨日粮中添加紫花苜蓿、红豆草等禾本科牧草对肉羊生产性能的影响,利用甘肃省通渭县三泰农牧专业合作社生产的饲草对比在同等的饲养管理水平下不同青贮产品在肉羊育肥上的增重效果。本试验选择体况中等、发育良好、健康无病、体重相近的3-4月龄30只羔羊作为试验羊。试验处理分为四组:50%紫花苜蓿+50%红豆草(带籽)、50%野草+50%燕麦草、全株玉米裹包青贮料、紫花苜蓿+红豆草+燕麦草+野草各25%的裹包青贮料。

In order to study the effect of forage grass （alfalfa, sainfoin, et al. ） on production performance of mutton sheep, different silages produced by Santai Agricultural and Husbandry Cooperatives of Tongwei County were used to compare the gain weight of fattening mutton sheep under the same management level. 30 healthy lambs （3-4-month） with medium body condition and similar body weight were selected. 4 treatments （50% alfalfa ＋50% sainfoin with seed; 50% weeds ＋50% oat grass; corn wrapped silage; 25% alfalfa＋25% sainfoin＋25% oat grass＋25% weeds） were carried out in this experient.
