The present study was undertaken to evaluate the immunopotentiating effect of medicinal plant products such as Withania somnifera, Tinospora cordifolia, Allium sativum and Azadirachta indica in commercial layer flock vaccinated against Newcastle disease and production parameters. The Haemagglutination inhibition (HI) titre values in all the groups were above the protective level throughout the study period. Similar results were obtained in ELISA. The cell mediated immune response was assessed by Leukocyte Migration Inhibition Test (LMIT) and there was a significant mean per cent inhibition in treatment groups. There was no change in egg production, egg shell thickness, albumen index, Haugh unit and yolk index between treatment and control groups. In conclusion, W. Somnifera (Ashwagandha, Amukkara kizhangu), (1%), T. Cordifolia (Guduchi, Seendhil kodi), (1%), Azadirachta indica (Neem, Veembu) (0.2%) and A. Sativum (Garlic, Poondu), (0.3%) can be used as an immunostimulant in poultry against Newcastle disease vaccination without affecting the egg production and egg qualities.
