    Abstract

    The present study was conducted to evaluate the effect of dietary supplementation of probiotic bacterium Bacillus licheniformis on the gut microbiota, growth and immune response in Macrobrachium rosenbergii juveniles (4.0 ± 0.02 g). Five isocaloric experimental diets supplemented with different concentrations of B. licheniformis, viz. Control (without probiotic supplementation), T1 (1.0 9 106 cfu g-1feed), T2 (1.0 9 107 cfu g-1feed), T3 (1.0 9 108 cfu g-1 feed) and T4 (1.0 9 109 cfu g-1 feed) were used for the experiment. After 60 days of feeding trial, the growth performance increases significantly in all the experimental groups compared with control, and highest weight gain, specific growth rate and lowest feed conversion ratio were recorded from T4 (P[0.05). However, juvenile survival was not found to be significantly affected by probiotic supplementation (P[0.05).
