ABSTACT Blighia sapida seed meal, BSSM was detoxified by traditional methods of soaking and boiling followed by chemical treatments using glycine and riboflavin. Detoxified BSSM was tested for nutritional adequacy using 120-day old Olympiad cockerel chicks and employing performance characteristics and nutrient retention as indicies of evaluation. Results showed that detoxified dietary BSSM included in diets at graded levels of 15, 17.50, 20 and 22.50 depressed feed consumption, growth rate, body weight gain and feed efficiency as the level of BSSM increased from 15% inclusion. Similar result was observed on protein retention while the utilization of dietary BSSM fat, fibre and mineral matter presented a reverse result. It is concluded that inclusion of detoxified BSSM beyond 15% may be harmful to the test animals. Further research to increase the percent supplementation of the chemical detoxifier (riboflavin and glycine) above the 5% level used in this study is recommended.
