摘　　要：试验旨在探究饲料中不同脂肪源对黄鳝(Monopterus albus)生长性能的影响,确定黄鳝养殖生产中最适的饲料脂肪源。试验选择体重约20 g的健康的黄鳝500尾,按照单因素实验设计,均分为5个处理组,每组5个重复,每个重复20尾黄鳝。各组黄鳝分别投喂以鱼油、豆油、棕榈油、亚麻籽油和菜籽油为脂肪源的饲料。投喂10周后,检测各组黄鳝的增重率、特定生长率及饲料系数等生长性能指标。结果显示,投喂含有鱼油和豆油的饲料之后,其试验末重、增重率和特定生长率显著高于投喂棕榈油组、亚麻籽油和菜籽油组(P<0.05)。投喂含有鱼油和豆油的饲料后,其饲料系数显著低于投喂棕榈油组、亚麻籽油和菜籽油组(P<0.05)。不同脂肪源饲料对黄鳝的脏体比和肝体比形体指标无显著影响(P>0.05)。研究结果表明,黄鳝养殖生产中使用鱼油和豆油对其生长性能效果较好,可以考虑使用豆油替代部分鱼油进行养殖。The aim of this experiment was to investigate the effects of different dietary fat sources on the growth performance of Monopterus albus,and to determine the most suitable dietary fat sources for the production of Monopterus albus.A total of 500 healthy eel with a body weight of about 20 g were divided into 5 treatment groups with 5 replicates per group and 20 eel per replicate according to a single-factor design.The eels in each group were fed diets with fish oil,soybean oil,palm oil,flaxseed oil and rapeseed oil as fat sources,respectively.After 10 weeks of feeding,the growth performance indexes such as weight gain rate,specific growth rate and feed coefficient of eels were measured.The results showed that the final weight,weight gain rate and specific growth rate of the diet containing fish oil and soybean oil were significantly higher than those of the diet containing palm oil,flaxseed oil and rapeseed oil groups(P<0.05).The feed coefficient of diet containing fish oil and soybean oil was significantly lower than that of diet containing palm oil,flaxseed oil and rapeseed oil groups(P<0.05).Different fat source diets had no significant effects on visceral-body ratio and hepato-body ratio of eel(P>0.05).The results showed that the use of fish oil and soybean oil in the production of eel had a good effect on its growth performance,and soybean oil could be considered as a substitute for some fish oil in culture.
