The experiment was conducted to evaluate the effect of onion (Allium cepa L.,) on the performance, gut microflora and intestinal histomorphology of broiler chicks. Three hundred and twenty day old broiler chicks (Ross) were randomly divided into four groups as A, B, C and D. Group A served as control without any supplementation, group B, C and D was supplemented with onion powder at the rate of 1.5, 2 and 2.5g/kg of feed respectively. Supplementation of onion significantly (P<0.05) increased weight gain and feed consumption. Supplementation of onion showed a significant (P<0.05) reduction in the population of E. coli and increased significantly Lactobacillus and Streptococcus species. Onion supplementation significantly (P<0.05) increased the morphometry of length, width, crypt depth and surface area of the villus in duodenum, jejunum and ileum of the small intestine. In conclusion, onion supplementation in broiler produced a positive effect on performance, gut microflora and intestinal histomorphology.
