A 28 days experiment was conducted to evaluate the effect of garlic and turmeric as additives on broiler chicken growth performance and gastrointestinal microbes at finisher phase. One hundred and eighty broilers (180) day old broiler chickens were utilized in four treatments diets namely T1 serves as the control diet, T2, T3, and T4 representing 0, 2.5g turmeric and 2.5g garlic mixture, 2g turmeric and 3g garlic mixture and 3g turmeric and 2g garlic mixture incorporated into 100kg of feed in a completely randomized design at finisher phase. Feed and water was provided ad libitum, and all customary regular management procedures were followed.  Broiler chickens diets were compounded to be iso-caloric and iso-nitrogenous (2700kcal/ME and 18%CP). Additionally, information was acquired about growth performance and gastrointestinal microbes. One way analysis of variance was employed by statistical software SPSS to examine the collected data. The results reveal no significant (P>0.05) differences in all growth parameters except in protein intake and energy intake which showed significant (P<0.05) differences. There was also a significant increase in protein intake and energy intake for animal fed T2, T3 and T4 diets compare to those in the control diet. There was Eschericia coli in birds fed T1 (+++), T2 (+++) and T3 (+++) but was moderately observed in T4 (++). Klebsiella spp was found in minute amount in T3 and T4 and completely absent in T2. It was determined that Supplementation of broiler chicken diets with  0.25% garlic and 0.2% turmeric and mixture improved protein intake and energy intake also the presence of Eschericia coli, Klebsiella spp.
