Abstract A 42-day trial was conducted to study the influences of fructo-oligosaccharides and mannan oli-gosaccharides on growth performance and serum biochemical parameters in juvenile turbot Scophthalmus maximus weighing (20 .53 ± 0 .10) g in a lab at water temperature of 14-18 .5 ℃ .The juveniles were fed the diets containing fructo-oligosaccharides at a rate of 0% (as control group) ,0 .1% ,0 .2% and 0 .5% and mannan oligosaccharides at a rate of 0% (control group) ,0 .1% ,0 .2% and 0 .4% .The results showed that the fructo-oligosaccharides led to significant increase in weight gain rate ,specific growth rate ,energy apparent digestibility and serum urea content ,and to lower food conversion ratio (P<0 .05) .The total protein content was found to be elevated with increase in mannan oligosaccharides level (P> 0 .05) .The juveniles fed the diets containing mannan oligosaccharides had higher food conversion ratio ,food intake , and crude protein and dry matter apparent digestibility as well as the total protein content (P>0 .05) ,and lower triglyceride content (P>0 .05) .The weight gain rate and specific growth rate ,energy apparent di-gestibility and serum urea content were increased with increase in mannan oligosaccharide level ( P<0 .05) .It is concluded that both fructo-oligosaccharides and mannan oligosaccharides promote the grow th of the juvenile via improvement of nutritional absorption and metabolism of protein and lipid .
