This study was conducted to investigate the effects of dietary inclusion of turmeric and thyme powders on performance, blood parameters and immune system of broiler chickens. In this study, 300, one-day old broiler chickens of the commercial Ross 308 strain were used in a randomized design with four treatment (five replicated in each treatment and 15 birds/replicated) and reared on the floor pens for 42 days. The dietary treatments were: (1) control diet (no supplement), (2) basal diet supplemented with 5 g/kg turmeric powder, (3) basal diet supplemented with 5 g/kg thyme powder and (4) basal diet supplemented with 2.5 g/kg turmeric powder + 2.5 g/kg thyme powder in diet. The results indicated that addition of different levels of turmeric and thyme powders increased chicks body weight in comparison to the control groups at 42 days of age (p>0.05). Further results showed no significant difference in feed intake among control and other treatment groups. Broilers receiving different levels of turmeric + thyme powders had highest feed intake and lowest FCR in compare to other groups. Broilers receiving turmeric and thyme powders had lower uric acid, total cholesterol, HDL, LDL and triglyceride concentrations compared to the control groups. The results showed that addition of turmeric and thyme powders were increased anti body newcastle and Influenza titres.
