The present study was conducted to evaluate the effect of dietary inclusion of garlic, turmeric and their combinations on performance of broilers (Cobb strain). Two hundred and forty day-old unsexed broiler chicks were procured and randomly divided into five dietary treatment groups (n=48). Birds in control (C) group were administered antibiotic levofloxacin at 2.5 g/l of drinking water, however, antibiotic was replaced with dietary inclusion of either 1% turmeric (T1), 1% garlic (T2), 0.6% turmeric+0.4% garlic (T3), or 0.6% garlic+0.4% turmeric (T4). The diets formulated were isocaloric and isonitrogenous. The feeding trial was conducted for 6 weeks. The results revealed significantly (P<0.05) higher cumulative feed intake in group T3, while body weight gain (g) showed no difference (P>0.05) among groups. Feed conversion ratio was found to be better in groups T2 and T4. Protein efficiency ratio was found to be higher in group T2 (P<0.05). The villi length of duodenum; epithelial and glandular epithelial height of jejunum, glandular epithelial height and diameter of glands of ileum were higher (P<0.05) in group T2. The 1% garlic supplemented group showed the best cost benefit ratio. It was concluded that 1% garlic powder supplementation in the diet may substitute antibiotics without any adverse effect in broilers.
