Chinese. 以豆粕、菜粕、棉粕为主要植物蛋白源,配制3种蛋白含量为46%的配合饲料，分别饲养人工繁殖的黄鳝苗（体质量12.56±1.17g）60d，探讨不同植物蛋白源饲料对黄鳝生长性能与肉质的影响。试验结果表明：棉粕组黄鳝增重率、特定生长率、蛋白质效率和饲料系数分别为145.01%、1.47%、88.2%和2.46，在3组中生长性能表现最佳，与其他2组差异显著，豆粕组；次之，菜粕组表现最差；3组黄鳝在肝体指数、内脏指数、肥满度方面均没有显著性差异豆粕组黄鳝肌肉粗蛋白含量3组中最高，显著高于其他2组；菜粕组黄鳝肌肉粗脂肪含量最高，显著高于豆粕组与棉粕组；豆粕组与菜粕组黄鳝在肌肉粗灰分方面并没有显著差异，棉粕组显著最低。

Soybean meal, rapeseed meal, cottonseed meal and white fish meal, fermented soybean meal were used as the main protein source. Three diets with 46% total protein from different plant resources were formulated to fed the fish with an average weight of 12.56±1.17g. The results showed that eel had the best performance in weight gain, specific growth rate, protein efficiency ratio and feed conversion ratio in the cottonseed meal group (CMP). In the soybean meal group (SMP), the crude protein content of eel muscle was significantly higher than the CMP group and rapeseed meal group (RMP). In the RMP group, the crude fat content of eel muscle was significantly higher than the other two groups. There were no significant differences of visceral somatic index, hepatosomatic index, condition factor among different treatments.
