Evaluation of Substituting Toasted Daniellia oliveri Seed Meal for Soybean Meal on the Performance and Economics of Production of Broiler Chickens

This study is aimed to evaluate the growth performance, nutrient retention, dressed and organ weights and economics of production using toasted Daniellia oliveri seed meal (TDSM) as a source of protein substitute with soybean meal (SBM) in broiler diets for 56 days. One hundred and fifty (150), one-day-old unsex Arbor Acre broiler chicks were randomly distributed into five treatments with 30 chicks each, replicated three times (10 chicks each) in a completely randomized design. Daniellia oliveri seed meal protein replaced soybean meal (SBM) at 0, 5, 10, 15 and 20%. Replacing SBM with TDSM protein up to 20% did not affect (P>0.05) growth, feed intake and feed conversion ratio (FCR). The substitution shows reduction in cost of feed intake per bird and percentage saving cost per bird of 13.55, 18.26, 31.77 and 33.2 at dietary 5, 10, 15 and 20% TDSM levels of inclusion. The nutrient digestibility dressed weight, gizzard, abdominal fat, liver, heart and pancreas were not affected (P > 0.05) by incorporating TDSM up to 20% in broiler diets. The results suggest that 20% inclusion level of toasted Daniellia oliveri seed meal could be effectively used without adverse effects on growth performance, nutrient digestibility, dressed and organ weights and with high production saving cost.
