  • Abstract : One hundred and fifty (150) one day old unsexed Ross 308 strain broiler chicks were used in this experiment to evaluate the effects of baker yeast (Saccharomyces cerevisiae) gradually replacing imported concentrate on the performance and carcass traits. Chicks were allocated into five treatment groups (A, B, C, D and E) in a complete randomized design, each group was replicated five (5) times each one with 6 chicks. Five iso-caloric, iso-nitrogenous diets were formulated, baker yeast replaced super concentrate in the ratios 0, 25, 50, 75 and 100%. Feed and water were served adlibitum. Chicks were vaccinated against gamboro. Body weight and feed consumption were measured weekly; average weight gain and FCR were calculated. Results obtained for weight gain and feed intake values were increased significantly by increasing the level of yeast replacement up to 50% then these values were decreased significantly by increasing of replacement above 50% . The mean values of feed efficiency were remained close similar between all groups. The levels of replacement had no significant effects on hot, cold dressing percentages, non-carcass yield, commercial cuts and subjective meat quality attri
