| 摘要: |
| 以初始体重为48.23±1.25 g的大黄鱼( Larimichthys crocea )为试验对象，研究饲料中添加胜肽和益生菌对大黄鱼生长性能、体组成的影响.添加胜肽试验组所用饲料为添加500mg/kg胜肽产品配制成软颗粒饲料；添加胜肽益生菌试验组所用饲料为添加500mg/kg胜肽产品和500mg/kg益生菌产品配置成的软颗粒饲料；对照组所用饲料为未添加胜肽和益生菌产品而以相同配方配制成的软颗粒饲料.整个养殖试验的周期为12周，并于海水浮式网箱中进行.结果表明，饲料中添加胜肽和胜肽-益生菌均显著提高大黄鱼的终末体质重( FW )、特定生长率( SGR )、鱼体增重率( WGR )、饲料效率( FE )和粗脂肪含量( p <0.05)；饲料中添加胜肽对大黄鱼水分、粗蛋白、灰分、肝脏指数( HSI)、内脏指数( VSI )和肥满度( CF )的影响不显著( p >0.05)；添加胜肽-益生菌饲料组 VSI 显著高于添加胜肽饲料组和对照组( p <0.05). |

| Abstract: |
| This experiment was conducted to investigate the effects of dietary Sheng peptides and probiotics on the growth performance and body composition of large yellow croaker ( Larimichthys crocea ) with initial average weight of 48.23±1.25 g. The Sheng peptides group was the soft particle feed added with 500 mg/kg Sheng peptides. The Sheng peptides probiotics group were fed by soft particle feed mixed with 500 mg/kg Sheng peptides and 500 mg/kg probiotics. The control group feed were the same soft particle feed without Sheng peptides and probiotics. The croakers were cultured in the net cages. After 12 weeks，the final weight( FW ), specific growth rate( SGR ), weight gain rate( WGR ), feed efficiency( FE ) and crude lipid content of Sheng peptides group and Sheng peptides probiotics group were significantly higher than those of the control group ( p <0.05). The effects of Sheng peptides on water content, crude protein, ash content, liver index ( HSI ), visceral index ( VSI ) and fatness ( CF ) on large yellow croakers were not significant ( p >0.05). The VSI of the Sheng peptides probiotics group were significantly higher than that of the Sheng peptides group and the control group( p ＜0.05). |
