摘要
试验依据牧草营养成分,对其进行能值分析,并进行能量载畜能力核定,结果表明,目前青海省生产使用的牦牛单位日需青草重量较大,可通过提高牦牛对牧草的采食率进行改善。
Based on nutuition component of pastures,analysed the emergy value,and checked the ability of stocking rate.The results showed that：at present the everyday pasture of yark unit is so large,and increasing grazing rate can perfect this condition.
