This study was carried out to determine the immunomodulatory effects of Asparagus racemosus extract-treated feed and to analyse the role of T and B cells in host defence against Newcastle disease in 1-week-old normal and immunocompromised boiler chicks. After the treatment, significant (P<0.01) positive effects were observed in both humoral and cell-mediated immune responses of birds, which were found to be evident by increased antibody titre after the haemagglutination inhibition test. The variation in skin thickness was significantly (P<0.01) more among herbal-treated groups than in non-treated groups, which was a clear marker for immunostimulation among birds.
