以初始体重（50.0±0.2） g的斑点叉尾（鱼回）（Ictalurus punctatus）作为试验对象,以不添加玉米干酒糟及其可溶物（DDGS）的饲料作为对照组饲料,在对照组饲料的基础上分别添加3%、6%和12%的玉米DDGS替代部分豆粕作为试验组饲料,研究饲料中添加不同水平玉米DDGS对斑点叉尾（鱼回）生长、体色、肉色、血清生化指标及肠道菌群结构的影响。对照组设置8个重复,每个试验组均设置5个重复,每个重复50尾鱼,养殖试验在水库网箱（1.5 m×1.5 m×2.0 m）中进行,共持续60 d。结果显示:饲料中添加不同水平玉米DDGS替代部分豆粕对斑点叉尾（鱼回）的存活率、增重率、特定生长率、饲料系数、摄食率、肝体比和...

A 56-day feeding experiment was conducted to evaluate the effects of different supplemental levels of corn distillers' dried grains with soluble (DDGS)in diets on the growth,body color,flesh color,serum biochemical indexes and intestinal microbiota structure of channel catfish (Ictalurus punctatus).In this experiment,channel catfish with the body weight of (50.0±0.2)g were used as experimental animals,the diet without corn DDGS was used as the diet of control group,and then supplemented with 3%(group D1),6%(group D2)and 12% (group D3)of corn D...
