Abstract：The effects of dietary xylo-oligosaccharides (XOS) on growth performance and immune function were investigated in 450 juvenile common carp (Cyprinus carpio) with an average initial body weight of (4 .93 ± 0 .03) g .The juveniles were randomly divided into five groups and fed basal diet ( as a control group ,CON) ,and the diet containing XOS at a rate of 0 .1% (group Ⅰ ) ,0 .2% (group Ⅱ ) ,0 .4%(group Ⅲ) ,or 0 .6% (group Ⅳ) .The results showed that there was significantly higher lysozyme activity in group Ⅳcompared with the control (P<0 .05) ,but no significant difference in alternative pathway of complement (ACH50 ) was observed in the treatment groups (P> 0 .05) .The expressions of iNOS and TNF-α were lower in the treatment groups than those in control group ,while the expressions of IL-1βand IL-10 genes were found to be up-regulated significantly (P<0 .05) ,without change in expression of TGF-βgene compared with the control group .The juveniles fed the diets containing XOS showed better growth performance than the fish fed the basal diet did ,with significant difference only between group Ⅳand the control group (P<0 .05) .The findings suggest that supplementation of XOS positively affect growth per-formance and immunity in common carp .
