Abstract :

Abstract[1] The present study investigated the effects of prebiotic inulin on the growth performance, survival, lactic acid bacteria population and body composition of common carp (Cyprinus carpio) juvenile. After acclimation, fish (initially average weight 6.25±0.12 g) were allocated into tanks (16 fish per tank) and triplicate groups were fed a control diet (27.7% protein and 7.15% lipid) or diets containing 0.5%, 1% and 1.5% inulin. At the end of trial growth factor, survival and body composition were assessed. At the end of study there were no significance difference in growth factor and survival rate between groups. LAB levels were significantly elevated in fish fed 1.5% dietary inulin. With the increase supplementation level of inulin, the mean value of protein increased, but the lipid carcass decreased (p < 0.05). The result indicated that inulin in the level of 1.5% can improved geowth perfomance and survival carp juvenile. *Corresponding authors; [e-mail]
