Litopenaeus vannamei is economically important shrimp species in worldwide aquaculture. This study was conducted to assess the effect of different levels of probiotic Pediococcus pentosaceus ( PP ) on growth performance, feed utilization, digestive enzyme activity, intestinal microflora count and body composition of L. vannamei . Four diets containing different concentrations [0 ( PP 0), 10 6 ( PPI ), 10 7 ( PPII ) and 10 8 ( PPIII ) CFU /g] of PP were formulated. After 8 weeks feeding trial, the experimental shrimps were challenged with Vibrio anguillarum and noted the surveillance. At the end of the feeding trial, the obtained results revealed a significant increase ( p < .05) in final body weight, final length, weight gain ( WG ), survival rate, protease and amylase activities, lactobacillus sp. and Bacillus sp. intestinal count, total haemocyte counts ( THC ) and lysozyme activity in PPIII group when compared with the other groups. Similarly, WG , amylase activity, Bacillus sp. count, THC and lysozyme activity were significantly enhanced in case of PPII compared to the control group ( p < .05). Interestingly, FCR and Vibrio sp. counts were significantly decreased in case of PPIII group when compared to the other groups ( p < .05). Also, significant level of surveillance was noted in the challenging test with V. anguillarum . These results suggested that the P. pentosaceus improved the growth performance, digestive enzyme activity, immunity and tolerance against V. anguillarum of L. vannamei .
