| 中文摘要: |
| 采用3×3因子试验法，设计了3种不同蛋白质水平（26％、29％、32％）及能量蛋白比水平（36、40、44kJ／g）的9种试验饲料，对体重（2．39±0．37）g的克氏螯虾（Procambarus clarkii）的适宜蛋白质含量及其蛋白能量比进行了研究，生长试验期42d。结果表明，克氏螯虾幼虾配合饲料中适宜蛋白质含量为29．49％～32．24％，饲料的适宜能量蛋白比范围为34．67～37．46kJ／g；当试验饲料蛋白质含量为31．86％，能量蛋白比为35．85kJ／g时，试验虾获得最大增重率、最低的饲料系数、最高的蛋白质效率及最大的特定生长率。 |
| 英文摘要: |
| The juvenile Procambarus clarkii with initial mean body weight （ 2.39 ± 0.37 ） g were fed diets containing 26%, 29% and 32% crude protein at dietary energy to protein ratio levels of 36, 40 and 44 kJ/g protein in a 3 × 3 factorial experiment. The results showe that the appropriate protein requirement and dietary energy to protein ratio ranges of Procambarus clarkii were 29.49% - 32.24% and 34.67 - 37.46 kJ/g protein respectively, the diet con- taining 31.86% protein with energy to protein ratio of 35.85 kJ/g protein was found to be the best one for juvenile Procambarus clarkii in the experiment. |
