Abstract: This experiment was conducted to evaluation the effects of Prebiotic, Garlic powder and Turmeric powder on performance and carcass characteristics of broiler chickens. Based a randomized completely design, 240 days old Ross 308 broilers were distributed into 16 floor pens and reared for 42 days. A basal diet was formulated according to NRC recommendations for starter (0-21 days) and grower (22-42 days) periods. The basal diet was also supplemented with prebiotic Biolex-MB, garlic powder and turmeric powder, resulting 4 dietary treatments were prepared including control group. Each dietary treatment was fed ad-libitum to 4 replicates group of 15 birds at the bigining of rearing period. The result of present study indicated that the diets containing feed additives had no significant effect on broilers performance with an except of Biolex-MB, which improved weight gain and feed conversion ratio (p<0.05). Supplementation of biolex-MB in diet significantly (p<0.05) affected the amount of carcass, thigh and breast (p<0.05). The highest percent of carcass and thigh were found in biolex-MB and control bird groups, respectively (p<0.05). The percent of breast was not affected whit feed treatments.
