The present study was conducted to evaluate the immuno-modulatory potential of Cajanus indicus leaves powder on dietary

supplementation in broiler birds. Day-old broiler chicks of Vencobb strain (n = 36) were randomly assigned into 3 treatments with 3 replicates each, 4 chicks (2 each for cell mediated and humoral immune response) in each replicate. The dietary treatments composed of the basal diet in control group, 0.05% Bacitracin Methylene Disalicylate added to the basal diet in standard group

and 1.5% Cajanus indicus leaves powder added to the basal diet in test group. The HA titre (as measured against sheep RBC) was signifi cantly (p<0.01) higher in birds of test group as compared to birds of control and standard group. There was signifi cant (p<0.01) elevation of cell mediated immunity (CMI) in broiler birds of test group as compared to control and standard group when evaluated by DNFB skin contact sensitization test. The result indicated that ration supplemented with Cajanus indicus leaves powder @1.5% signifi cantly improved cellular and humoral immune responses in broiler birds.
