A 60-day feeding trial was conducted to evaluate the effect of dietary nucleotide on growth, survival, immunity and resistance to white muscle disease and Aeromonas hydrophila infection in freshwater prawn (Macrobrachium rosenbergii). The nucleotide was supplemented at 0, 1.5, 2.25 and 3.0 g/kg diet. The test diets were fed for 60 days in triplicate groups of prawns, which had initial weight of 0.27 g. At the end of the feeding trial, growth was recorded and non-specific immune parameters, such as, prophenol oxidase activity, superoxide anion production, total haemocyte count and total serum protein, were studied in haemolymph samples. Phenol oxidase activity and superoxide anion production were significantly (P < 0.05) higher in prawns fed nucleotide-based diets. Total haemocyte count and haemolymph were higher (P < 0.05) in prawns fed nucleotide-based diets. The relative per cent survival of prawn after the challenge test against white muscle disease was significantly (P < 0.05) higher in prawn fed nucleotide-incorporated diets. However, there was no effect of nucleotide supplementation on growth and survival of prawn.
