摘要：The potentials of Leucaena leucocephala leaf-meal as a supplementary protein in fish feed as evaluated. Leucaena leaves were subjected to two processing methods (sundrying and boiling) to determine the effect of these treatments on proximate composition and anti-nutritional factors. Five samples of Leucaena leaves were analyzed, sundried for 24 hours (SD 1 ), sundried for 48 hours (SD 2 ), sundried for 72 hours (SD 3 ), soaked in boiled water for five minutes at 100°C (SB 5 ) and unprocessed (SU). The tests were carried out in triplicate for each treatment. Data obtained were subjected to one way analysis of variance. Sun-drying (SD 1 , SD 2 , SD 3 ) led to a significant (P≤0.05) increase in crude protein, ash, phosphorus, potassium, magnesium and sodium when compared with the soaked in boiled water (100°C) for 5 minutes (SB 5 ) treatment. The sample soaked in boiled water for 5 minutes (SB 5 ) gave 73, 90, 81, 97 and 36 % reduction in the levels of phytate, cyanide, tannin, saponin and mimosine respectively, which was better than the sundried treatments. Key Words : Leucaena leucocephala , anti-nutritional factors, nutritional composition, supplementary protein, mimosine, fish feed.
