				Abstract 
 
              
              
              Aim: 
              
              In this study, a planned research work was conducted to 
              investigate the nutrigenomic aspects of supplementation of 
              
              
              Allium sativum 
              
              (garlic) and 
              
              Ocimum sanctum 
              
              (holy basil) leaf powder on the growth performance and immune 
              characteristics of broilers. 
              
              
              Materials and Methods: 
              A 
              6 weeks feeding trial was conducted with 280-day-old Ven Cobb 
              broilers, distributed randomly into seven experimental groups. 
              Each treatment had 4 replicates with 10 birds each. The birds of 
              the control group (T1) were fed a basal diet formulated as per BIS 
              standards. The broilers of treatment groups T2 and T3 were fed 
              basal diet supplemented with the commercially available garlic 
              powder (GP) at levels of 0.5% and 1.0% of the feed, respectively, 
              while broilers in T4 and T5 were fed basal diet supplemented with 
              commercial grade holy basil leaf powder (HBLP) at levels 0.5% and 
              1.0% of the feed, respectively. Birds in the T6 were fed with 0.5% 
              GP and 0.5% HBLP, whereas T7 was fed with 1.0% GP and 1.0% HBLP. 
              At the end of the feeding trial (6th week), blood samples were 
              collected and analyzed for relative mRNA expression of toll-like 
              receptors (TLR) 2, TLR 4 and TLR 7 using real-time polymerase 
              chain reaction. 
              
              
              Results: 
              
              The mean body weight gain and feed conversion efficiency were 
              improved (p<0.05) in broilers fed the GP and HBLP incorporated 
              diets compared with the control group. The relative mRNA 
              expression levels of TLR 2, TLR 4 and TLR 7 in the peripheral 
              blood of the broilers were found to be increased (p<0.05) in the 
              birds supplemented with graded levels of the GP and HBLP as 
              compared to the untreated group. 
              
              
              Conclusion: 
              
              The present work concludes that the inclusion of GP and HBLP could 
              enhance the production performance and immune status of birds by 
              augmenting the T-cell mediated immune response and thereby 
              protects them from disease without decreasing growth traits as a 
              possible substitution to conventional antimicrobials.
