试验旨在研究不同蛋白能量比的饲料对黄金鲫幼鱼生长和体组成的影响。以初始体重为（7.50±0.02）g的黄金鲫幼鱼为试验对象，随机分为9组，每组设3个重复，每个重复30尾鱼，分别投喂由3种不同的蛋白水平（30%、35%、40%）和3种不同的脂肪水平（6%、8%、10%）组成的9种不同蛋能比（从21.6~30.9 mg/kJ）的试验饲料，进行为期8周的生长试验。结果表明，饲料蛋白水平显著影响黄金鲫的生长、饲料效率和蛋白质效率（P<0.01），随着饲料蛋白含量的增加，黄金鲫的增重率和特定生长率显著提高，最高值均发生在蛋白/脂肪为40/10（29.2 mg/kJ）组，显著高于饲料蛋白含量为30%的各组（P<0.05），与蛋白含量为35%的各组之间没有显著差异（P>0.05）。同样的，饲料效率随着蛋白含量的增加也显著提高，蛋白/脂肪为35/8（26.5 mg/kJ）和40/10组的饲料效率最高。蛋白质效率最高值发生在蛋白/脂肪为35/8组，显著高于蛋白含量为40%的处理组，但与其它组没有显著差异。饲料不同蛋能比对鱼体水分没有显著影响，鱼体脂肪含量与饲料脂肪含量正相关。综合试验结果，黄金鲫适宜的蛋能比水平为25.5~26.5 mg/kJ，蛋白质为35%，脂肪为6%~8%。
試驗旨在研究不同蛋白能量比的飼料對黃金鯽幼魚生長和體組成的影響。以初始體重為（7.50±0.02）g的黃金鯽幼魚為試驗對象，隨機分為9組，每組設3箇重複，每箇重複30尾魚，分彆投餵由3種不同的蛋白水平（30%、35%、40%）和3種不同的脂肪水平（6%、8%、10%）組成的9種不同蛋能比（從21.6~30.9 mg/kJ）的試驗飼料，進行為期8週的生長試驗。結果錶明，飼料蛋白水平顯著影響黃金鯽的生長、飼料效率和蛋白質效率（P<0.01），隨著飼料蛋白含量的增加，黃金鯽的增重率和特定生長率顯著提高，最高值均髮生在蛋白/脂肪為40/10（29.2 mg/kJ）組，顯著高于飼料蛋白含量為30%的各組（P<0.05），與蛋白含量為35%的各組之間沒有顯著差異（P>0.05）。同樣的，飼料效率隨著蛋白含量的增加也顯著提高，蛋白/脂肪為35/8（26.5 mg/kJ）和40/10組的飼料效率最高。蛋白質效率最高值髮生在蛋白/脂肪為35/8組，顯著高于蛋白含量為40%的處理組，但與其它組沒有顯著差異。飼料不同蛋能比對魚體水分沒有顯著影響，魚體脂肪含量與飼料脂肪含量正相關。綜閤試驗結果，黃金鯽適宜的蛋能比水平為25.5~26.5 mg/kJ，蛋白質為35%，脂肪為6%~8%。

A growth experiment was conducted to determine the optimal dietary protein to ener-gy (P/E) ratio for juvenile gold carp [initial average weight (7.5 ± 0.02) g]. Nine practical diets were formulated to contain three protein levels(30%, 35%and 40%), each with three lipid levels (6%, 8%and 10%), in order to produce a range of P/E ratios(from 21.6 to 30.9 mg/kJ). Each di-et was randomly assigned to triplicate groups of 30 fish. The feeding trial lasted for 8 weeks. The results showed that the dietary protein level significantly influenced the growth, feed effi-ciency (FE) and protein efficiency ratio (PER) (P<0.01). The weight gain and specific growth rates (SGR) of fish were significantly improved with the increasing dietary protein (P<0.05), and the peak value occurred in fish fed the diets with 40% protein and 10% lipid (29.2 mg/kJ), which was significantly higher than that fed with 30% dietary protein, however, no significant difference was observed between 35% and 40% dietary protein treatments. Similarly, FE was significantly improved with the increasing di-etary protein, and the peak value occurred both in fish fed diets with 35% protein and 8% lipid (26.5 mg/kJ) and in fish fed diets with 40% protein and 10% lipid. However, the highest PER was observed in fish fed di-ets with 35% protein and 8% lipid, which was significantly higher than fish fed diets with 40% protein, but no significant difference was found compared with any other groups. No significant differences were observed in moisture content of fish in different dietary P/E ratio treatments. Carcass lipid content positively correlates with dietary lipid level. These results sug-gest that the diet containing 35% protein and 6% or 8% lipid with P/E of 25.5 to 26.5 mg/kJ is optimal for gold carp.
