Effect of Tulsi dry leaf powder (OLP) was studied on cell mediated and humoral immune responses of broiler chickens experimentally infected with S. Gallinarum. Administration of Tulsi DLP @ 5g/kg of feed enhanced cell mediated immune response as observed by DTH in terms of increased foot pad skin thickness to sonicated bacterial cell protein (sbcp) antigen. It also enhanced humoral immune response against S. Pullorum plain antigen as detected by standard tube agglutination (SAT) test. The present findings indicate that Tulsi DLP has an immunopotentiating effect.
