摘　　要：为了探索地鳖虫后若虫期对蛋白质、能量等营养物质的需要量 ,通过双因子交叉分组试验 ,比较了不同能量、蛋白质水平的配合日粮对地鳖虫后若虫期生长速度和饲料转化率的影响。结果为 :在蛋白质水平组中 ,1、2、3、4、5水平组粗蛋白质含量分别为 1 9 1 3 %、1 8 0 9%、1 7 0 7%、1 6 1 0 %、1 5 1 3 % ,日增重与其它水平组差异显著 (P <0 0 5 )或极显著 (P <0 0 1 ) ;在能量水平组中 ,A、B、C水平组消化能为 1 3 2 7、1 2 2 6、1 1 2 8mJ kg ,日增重与其它水平组差异显著 (P <0 0 5 )或极显著 (P <0 0 1 )。结合各处理间饲料转化率的差异情况 ,筛选出地鳖虫后若虫期蛋白质和能量适宜需要量为 :粗蛋白 1 5 1 3 %～ 1 6 1 0 % ,消化能 1 1 2 8mJ kg。The cross-over design containing two factors (protein and energy) was arranged to compare the effects of different levels of protein and energy of ration formulations on growth rate of late period larvae of Eupolyphaga sinensis and the feed conversion efficiency, and then to explore the requirement for protein and energy in late period larvae of E.sinensis. The results show that the group Ⅰ-Ⅴ based on different levels of protein, with contents of crude protein of 19.13%,18.09%,17.07%,16.10% and 15.13% respectively, has significant differences(P<0.05 or P<0.01) in daily gain. Group A, B, C based on different levels of energy, with digestible energy of 13.27 mJ/kg, 12.26 mJ/kg and 11.28 mJ/kg respectively, has significant differences (P<0.05 or P< 0.01) in daily gain. Considering the differences of feed conversion efficiency in each treatment group, it is suggested that the content of crude protein be 15.13%-16.10%, and digestible energy be 11.28 mJ/kg on late period larvae of E.sinensis.
