Evaluation of Lactobacillus plantarum as feed supplement on host associated microflora, growth, feed efficiency, carcass biochemical composition and immune response of giant freshwater prawn, Macrobrachium rosenbergii (de Man, 1879)

The present experiment was conducted to evaluate probiotic effect of Lactobacillus plantarum on giant freshwater prawn, Macrobrachium rosenbergii. A 90-day feeding trial was conducted by feeding prawn juveniles (mean weight±SE: 0.54±0.03g) with three experimental diets prepared by supplementing basal diet (Crude protein: 38%; Gross energy: 387kcal100g−1) with different concentrations of probiotics bacteria viz. T1 (107cfug−1 diet), T2 (108cfug−1 diet), T3 (109cfug−1 diet) and control diet (unsupplemented diet). In the present study, growth parameters viz. WG% and SGR and feed utilization parameters viz. FCE, FCR and PER increased significantly (P0.05). The carcass protein content increased significantly (P
