对幼莱兰(鱼師)投喂含高蛋白质的鱼粉、脂类和碳水化合物的饵料,对照饵料含脂类和碳水化合物饲养30天,以确定其生长、食物转换和鱼体成份。对照组鱼生长快、饵料效率高,高蛋白质组和高碳水化合物组居中,而高脂类组则低。对照组表明蛋白质和能量滞留量最高,同样在对照组中由于食用脂类和碳水化合物增加,使每增重100克体重所 Dietary fish lipid, lipid, and carbohydrate-containing diets were fed to Youngilan (fish division), and the control diet contained fat and carbohydrates for 30 days to determine their growth, food conversion and body composition. In the control group, the fish grew fast, the feed efficiency was high, the high protein group and the high carbohydrate group were medium, while the high-fat group was low. Control group showed the highest retention of protein and energy, also in the control group due to increased consumption of lipids and carbohydrates, so that each weight gain of 100 grams of body weight
