This study was carried out to determine the growth performance and carcass characteristics of broilers fed diets containing differently processed sesame seed meal (SSM). Five experimental diets were formulated with diet 1 (control) containing 0% SSM, while diets 2 to 5 contained sundried (Su), roasted (Ro), boiled (Bo) and soaked (So) sesame seed meal each at 15% inclusion level respectively. One hundred and eighty (180) one day-old broiler chicks average 42.15g sourced from a commercial hatchery were allocated into 5 treatments of 12 birds in 3 replicates in a completely randomised design and dietary treatment lasting 56 days. Roasting and soaking significantly (P<0.05) reduced the antinutritional factors in sesame seed meal better than sun drying and boiling. Final body weight, average weight gain and average daily weight gain were significantly different (P<0.05) among the treatments. Control, Ro, Bo and So showed better utilisation of feed than Su. Total feed consumption and average daily feed intake were significantly (P<0.05) higher among birds fed So. There were significant (P<0.05) differences among carcass parameters and organs weight measured between the control diet and other treatments. It can be concluded that roasting and soaking were adequate to remove toxic phytochemicals in sesame seed meal to tolerable levels for broiler diets and inclusion up to 15% of Ro and So is recommended. At these levels, growth and carcass characteristics were not significantly affected compared to the control diet.
