摘　　要：试验将驼绒藜按不同精粗比配合成颗粒日粮饲喂苏尼特羊,对比分析驼绒藜日粮与苜蓿日粮、谷草日粮对羊增重的效果。结果表明,华北驼绒藜、苜蓿、谷草铡短粉碎与50%、30%精料混合制成颗粒日粮对绵羊体增重效果最好,日增重可达127g/d;在荒漠草原区,苜蓿的高价格是限制其推广的主要原因;华北驼绒藜和谷草在30%精料水平下,与同精料水平条件下用苜蓿饲喂绵羊具有相同的增重效果,并可增加纯收入80元/只。Ceratozdes arborescens was a considerable amount of forage resource, but the understand level of feeding value had rest on a traditional standard. So the feeding value experiment was developed in order to fully understand and utilize Cera- tozdes arborescens. The experiment was conducted to feed sheep on particle diet combined by Ceratozdes arborescens in different ratio of concentrate to roughage. Then the weight gain caused by Ceratozdes arborescens diet, alfalfa diet and millet straw diet on sheep were analyzed comparatively. The results showed that the largest weight gain appeared at the particle diet which made from powder of Ceratozdes arborescens, alfalfa and millet straw mixed with 50% and 30% concentrated feed were the best, the daily gain was 127 g/d. In desert steppe, the primary cause of limiting alfalfa popularization was high price. In the level of 30% concentrated feed, the Ceratozdes arborescens and millet straw had the same weight gain effect as alfalfa, and could in crease net income by 80 yuan per sheep.
