Two hundred and ten day-old Arbor acre broiler chicks were used to assess the protein quality of raw and toasted Daniellia oliveri seed meal (DOSM) on performance, haematology, and some biochemical indices. Seven treatment diets that contained 0% (control), 2.5, 5.0 and 7.5% raw DOSM and 2.5, 5.0 and 7.5% toasted DOSM respectively were randomly assigned to seven groups of 30 birds each, replicated thrice with 10 birds per replicate in a completely randomized design. Chemical analysis indicated that raw DOSM contained (% DM) 26.50 crude protein, 6.02 crude fibre, 4.30 ether extract, 4.06 ash and 47.47 carbohydrate. The results of the crude fibre (3.19%), ash (2.8%) and nitrogen free extracts (40.51%) were reduced after toasting while the crude protein (28.60%) and ether extract (7.85%) increased. The raw DOSM contained (mg/100g) tannin (2.23), phytic acid (30.39), oxalate (20.02), hydrocyanide (6.05) and saponin (2.08). Toasting treatment eliminate almost completely the anti nutritional compounds in the seeds. Performance data indicate that body weight gain and feed to gain ratio were significantly (P0.05) but differed (P |
