摘　　要：探讨育成前期海狸鼠饲粮中能量的适宜水平。实验分四组,饲粮的消化能和消化蛋白质水平分别为12330.5kJ/kg、15.70%;13061.8kJ/kg,15.29%;14210.0kJ/kg、15.13%;14818.2kJ/kg、15.08%。实验结果表明,饲粮消化能水平为14210～14818kJ/kg,日消化能1563～1633kJ 时,海狸鼠增重最好。Here the proper level of energy are approached ih the diet of pre-mature male nutria.These experiment consists of feeding experiment,experiment of digestion and metabolism.The nutrias were divided into 4 groups.The content of digestible protein in group equals each others,but the level of digestible energy is 12330.5、13061.8, 14210.0、14818.2 kJ/kg respectively.The digestible rate of protein and energy in feed and the depositing rate of protein were measured and analyzed.The results of the experiment showed that when digestible energy was 14210～14818 kJ/kg in the diet,the male nutrias of 2～3 months old can rise in their weights quickly.
