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).
