Potentials of toasted African yam bean seed meal supplemented with multi-enzyme on performance characteristics and blood serum of broiler starter chickens

A feeding trial was conducted for 4 weeks to evaluate the potentials of toasted African yam bean seed meal (TAYBSM) on performance characteristics and blood serum of broiler starter chicken with multi enzymes supplementation. Enzyme was supplemented at the rate of 400g/1000kg of feed (0.40g/1.00kg) except control (T1). TAYBSM was used to replace soybean meal at 0, 20, 40, 60 and 80% inclusion levels. Two hundred (200) day-old Marshal® broiler chicks were randomly allotted to five dietary treatments (T1, T2, T3, T4, and T5) of 40 birds each, replicated four times with 10 birds per replicate in a Completely Randomized Design. Data were collected on daily feed intake and weight gain. Blood samples were collected from two birds per replicate into plain sample bottles by using needle and syringe and transferred to the laboratory for assay. The outcome of the study revealed no significant differences (P>0.05) in the blood serum while performance characteristics showed significant differences (P<0.05). Toasted African yam bean seed meal with multi enzyme supplementation should be encouraged to replace soybean meal in broiler diets up to 80% inclusion level without any adverse effect on performance characteristics and blood serum.
