Quantitative replacement of soybean meal with toasted African yam bean ( Sphenostylis stenocarpa ) meal in broiler starter diets

Eighty-four Anak broilers were used to study the effect of quantitative replacement of toasted soybean meal (TSBM) with toasted African yam bean (TAYB) meal in broiler starter diet. The experimental design was completely randomized design (CRD). There were four treatments each replicated three times with seven broilers per replicate. The inclusion levels of toasted African yam bean meal in diets were 0, 25, 50 and 75% in treatments I, II, III, and IV respectively. The parameters measured were final live weight, feed intake, feed conversion ratio (FCR) and cost/kg feed. Results showed that the starter broilers fed treatment IV diet had significantly (P 0.05) between starter broilers fed treatment I and treatment II. From the result, one can conclude that 25% AYB (treatment II) compared favourably with the control diets 0% AYB in starter broiler diets and is hereby recommended as optimal for quantitative replacement of soybean in broiler starter diet.
