摘要通过饲养试验，研究了饲料营养成分对团头鱼补偿生长的影响。测试了三种饮食：对照组、高蛋白(HP)和高蛋白和碳水化合物(HPC)饮食。将三种饲料分别投喂给团头鱼(初始体重为24±0.50 g)60d，分别采用饱食(每天投喂)和限制投喂(连续3d不投喂，接下来的12d投喂)。饲喂HP和HPC饲料的鱼体增重显著高于对照组。此外，限制饲喂导致的体重增加显著低于每日饲喂的对照组和惠普饲料。然而，在两种饲养方式下，投喂高碳水化合物饲料的鱼的增重没有显著差异。投喂对照饲料的鱼的饲料转化率显著高于投喂HP和HPC饲料的鱼。此外，这一比例也很高。
AbstractA feeding trial was conducted to evaluate the influences of dietary nutrient composition on the compensatory growth of Blunt Snout Bream Megalobrama amblycephala. Three diets were tested: a control, a high-protein (HP), and a high-protein and carbohydrate (HPC) diet. Each of the three diets was fed to Blunt Snout Bream (initially weight, 24 ± 0.50 g) for 60 d using either satiation feeding (in which fish were fed daily) or restricted feeding (no feeding for 3 d followed by feeding for the next 12 d). The weight gain of fish fed the HP and HPC diets was significantly higher than that of fish fed the control diet. In addition, restricted feeding led to significantly less weight gain than daily feeding with the control and HP diets. However, there was no significant difference between the two feeding regimes in the weight gain of fish fed the HPC diet. The feed conversion ratio of fish fed the control diet was significantly higher than that of fish fed the HP and HPC diets. Moreover, the ratio was si...
