              Abstract 
 Aim:
              Present experiment was designed to study the effect of 
              supplementation of garlic and neem leaf powder (NLP) on growth 
              performance and carcass yields in broilers. 
              Materials and Methods: A total of 210-day-old commercial male 
              broiler chicks (Ven Cobb) were procured and randomly distributed 
              in to seven treatments, each treatment had six replicates with 
              five chicks per each replicate. Growth trial was conducted in a 
              randomized block design comprising seven dietary treatments. T1 
              was served as control. T2 and T3 were fed with garlic powder (GP) 
              0.5, 1 g/kg feed respectively. T4 and T5 were given with NLP 1, 2 
              g/kg feed respectively. T6 was fed with 0.5 g/kg GP and 1.0 g/kg 
              NLP. T7 was treated with 1.0 g/kg GP and 2.0 g/kg NLP. The body 
              weight, feed consumption of individual bird was recorded at weekly 
              interval and the body weight gain, feed conversion ratio (FCR) 
              were calculated. At the end of 42 day, six birds from each dietary 
              group were sacrificed to estimate the dressing yield and relative 
              weights of giblet (liver, heart and gizzard). 
              Results: Supplementation of garlic and NLP alone and their 
              combination significantly (p<0.05) improved the body weight gain 
              and FCR whereas no significant (p>0.05) influence was observed in 
              carcass parameters like dressing yield and giblet yield (heart, 
              gizzard and liver) in all treatment groups.  
              Conclusions: Supplementation of GP alone showed poor 
              performance, but when it was supplemented in combination with NLP 
              there was improvement in performance parameters. These results 
              indicated that the combination of GP and NLP can be used as 
              alternates to coccidiostats for improving the performance. Such 
              meat can be used as a designer meat as fetch higher price if 
              marketed as branded item. 
              Keywords: body weight gain, carcass yield, feed conversion 
              ratio, garlic, neem.
