摘　　要：研究旨在探讨饲料中添加天然着色剂对黄颡鱼生产性能和生理机能的影响。挑选健康活泼、体重均匀[(10.4±0.1)g]的黄颡鱼随机分成5个组,对照组饲喂基础饲粮,试验组分别在基础饲料中添加天然着色剂(金碧黄)0.1%0、.2%、0.4%、0.8%,饲养周期60 d。结果表明,随着着色剂添加量的增加,黄颡鱼成活率逐渐提高,饵料系数逐渐下降,0.8%着色剂的添加能显著提高黄颡鱼的成活率,显著降低饵料系数(P<0.05);各试验组增重率较对照组均有所提高,但差异不显著(P>0.05);着色剂的添加,对黄颡鱼肝胰脏ALT活性,血清SOD、溶菌酶活性无显著影响(P>0.05)。The study aimed to explore the effect of natural colorant in feed on performance and physiological function of pelteobagrus fulvidraco.Pelteobagrus Fulvidraco,being clinical healthy,having even weight [（10.4±0.1） g],were selected and divided into five groups randomly.Control group fed basic diet,and treat group added 0.1%,0.2%,0.4%,0.8% natural colorant（Leader gold yellow,LGY） among basic diet respectively,and tested for 60 days.Results showed： Survival rate improved gradually along with the increase of LGY,While the coefficient of feed decreased with the supplement of LGY.The addition of 0.8% LGY could provide survival rate and decreace coefficient of feed（P0.05）;The growth rate for each treat group is higher than the control group,but no significant difference（P0.05）;The addition of LYG had no significant effect on the hepatopancreas ALT activity,serum SOD activity and lysozyme activity（P0.05）.
