AB  - African Yam Bean (AYB) meal and Nutrase-xyla enzyme were evaluated for their nutritive and economic efficiency in broiler starter diets.  Six diets were formulated, a control (D<SUB>1</SUB>) and five others.  AYB meal and fish meal were the major plant and animal protein sources.  Diets 2,3,4,5 and 6 were supplemented with nutrase-xyla enzyme at 10g/100kg, 20kg/100g, 30g/100kg, 40/100g and 50g/100kg diet respectively.   The calculated percent crude protein of the diets was 25 while metabolizable energy was 3100kcal/kg.  One hundred and forty-four (144) day-old unsexed Anak 2000 strains of broiler chicks were used for the trial.  Each treatment consisted of 3 replicates of 8 birds in a Completely Randomised Design (CRD).  The experiment lasted 5 weeks.  The results showed that the mean body weight gain and feed-to-gain ratio were significantly (P&lt;0.05) depressed.  D<SUB>1</SUB> had the highest body weight gain (603.02g) while diets 2,3,4,5 and 6 were 331.66g 300.83g, 300.56g, 342.36g and 341.25 respectively.  The total revenue realizable from Diet 1 (N361.81) was significantly (P&lt;0.05) higher than the other diets.  It was therefore concluded that the use of AYB meal with or without nutrase-xyla enzyme supplementation is not efficient and research efforts need be made towards the provision of appropriate characterization of AYB carbohydrate, protein and anti-nutritional components to allow for development of appropriate enzymes and toxin binders that could enhance their nutritive value and utilization.
