摘　　要：冷季饲草料中粗蛋白和干物质含量是肉牛生产性能提高的重要因素,而且饲草料资源的不同组合对肉牛生产性能的影响也有很大差异,通过对青海省冷季饲草料的干物质和粗蛋白的分析,并对三组试验动物喂食三种不同日粮后,对消化率、增重、料肉比的统计数据进行方差分析后,发现日粮的组分的选择、配比与肉牛的增重、料肉比的关系,并讨论了青海省农区冷季饲草料的资源状况,在饲草料的组分、配比方面给出了科学的建议。Crude protein and dry matter content of forage in cold season is important tactor for improving performance of beef production.Different composition of forage resource has great impact on beef production.Dry matter and crude protein has been analysed.Three different diet composition were fed, Digestion rate,gaining weight,ratio of meat and feed were studied statistically;Optimizing diet composition relation.Discussing forage resource situation.
