摘　　要：为了研究青贮全株玉米与青贮全株甜高粱饲喂肉羊效果,本试验将40只小尾寒羊羔羊随机分为2组,试验Ⅰ组为青贮玉米组,试验Ⅱ组为青贮甜高粱组。结果表明:饲喂青贮甜高粱组羊只的采食量比青贮玉米组提高了13.25%,平均体重稍高于青贮全株玉米组羊只(P>0.05);饲喂青贮甜高梁组羊只的总增重和日增重均显著高于饲喂青贮全株玉米组羊只(P<0.05),且试验Ⅱ组比试验Ⅰ组日增重提高了13.9%,增重明显,效果良好。This experiment was to explore the effect of corn silage and sweet sorghum silage feeding mutton sheep.40 small-tailed Han sheep lambs were randomly divided into two groups.The experimental group I was silage corn group and the test group II was silage sweet sorghum group.The results showed that the feed intake of the silage-sweet sorghum group was 13.25% higher than that of the silage corn group,and the average body weight was slightly higher than that of the silage whole corn group (P>0.05).The total weight gain and daily gain of the sheep fed the silage sweet sorghum group were significantly higher than those of the silage whole corn group \%(P\%<0.05),and the daily weight gain of the test group II was 13.9% higher than that of the group I.The weight gain effect of Experiment II was better than that of Experiment I.
