              Abstract
              
                
                            
                            The present study was aimed to evaluate the 
                            immunomodulatory efficacy of polyherbal formulation 
                            Stresroak along with effect on performance in 
                            broiler chicken. Four hundred and fifty healthy days 
                            old chicks were randomly divided into three groups 
                            (each group consisting of 150 chicks). Group A 
                            served as a negative control while group B served as 
                            positive control supplemented with levamisole, a 
                            known immunomodulator @ 15 mg/kg body weight through 
                            water for four consecutive days from third day 
                            onwards. Group C birds supplemented with Stresroak 
                            were administered @ 1 kg /tone of feed for 
                            consecutively for 11 days i.e. 5 days before and 5 
                            days after vaccination. Parameters under study were 
                            performance traits viz, body weight gain, feed 
                            consumption, FCR, blood samples were collected at 
                            weekly interval for evaluation of various 
                            haematological, biochemical immunological and 
                            histopathological examination parameters. Results 
                            revealed that the antibody titre, total proteins and 
                            globulins were increased significantly in the birds 
                            receiving Stresroak as compared to untreated control 
                            group. Performance parameters were improved 
                            non-significantly as compared to untreated control 
                            (Group A). Histopathologically varying degrees of 
                            lympho-proliferative changes noted which reveals 
                            increase number of lymphocytes. It was concluded 
                            that Stresroak exhibits hematinic, hepato-protective 
                            and Immunomodulator properties

                            Polyherbal, Hematinic, Hepato-protective.
