Abstract


The objective of this study was to investigate the effect of feeding raw and processed African yam bean (AYB) Sphenostylis stenocarpa on the performance and nutrient utilization of broiler chickens. The experiment utilized one hundred and twenty one day old Abor-Acre broiler chicks in 56-days intensive feeding trial. Four dietary treatments comprising a basal maize-soybean meal diet and three differently processed AYB meals were used to replace soybean at 50% protein for protein in the basal diet (raw, aqueous heating and dehulled AYB). There were four 4 treatments groups of 3 replicates with 10 birds per replicate. Birds were randomly divided into four groups in a completely randomized block design. It was revealed that a 50% protein for protein replacement of SBM with cooked AYB was equally as good as feeding SBM as protein source in diet of broiler chicks. Hence, Aqueous heating was a better processing method for African yam bean compared to dehulling or better still dehulling prior to aqueous heating to enable adequate removal of the anti-nutritional factors to the barest minimum.
