Abstract: | ImmuPlus, a polyherbal commercial formulation was used to modulate the immune system of commercially important giant freshwater prawn M. rosenbergii. The prawns were fed with basal diet supplemented with ImmuPlus at 1g/kg feed for 4 weeks. Results showed that the phenoloxidase activity (PO), haemagglutination and lysozyme activities were significantly elevated in ImmuPlus-fed prawn up to 3 weeks of feeding and declined after 4 weeks of feeding. The total protein level in ImmuPlus-fed prawn raised up to 2nd week of feeding. Incorporation of ImmuPlus at the rate of 1g/kg feed in the diet of prawn for 3 weeks may be beneficial in raising the immune status of prawn. |
