dc.description.abstractThe seeds of Albizzia lebbeck were processed and chemically analyzed for their proximate composition, anti-nutritional factors and amino acid profile. Results obtained from the first phase of the experiment determined the particular treatments that were used for the feeding trial. Four isoproteic (40% crude protein) diets were formulated with same protein ingredients and basal ingredients and fed at 5% body weight to groups of Clarias gariepinus juveniles of mean initial body weight of 15.8 ± 0.4g in eight out-door concrete tanks each measuring 1.3m x 0.9m x 1m capacity (1.17m3) for 8 weeks. Proximate composition of the different Treatments showed that they had low moisture content (2.47 – 5.29%). The seeds were found to be rich in crude protein (29.73 – 38.04%) and carbohydrates (32.28 – 37.47%) but low in lipid content (5.08 – 6.87%). The phytochemical screening of the seeds showed the presence of anti-nutritional factors, however, tannin levels were negligible while cyanogenic glycoside and phytic acid levels were low. The amino acid levels of histidine and leucine were adequate when compared with the Essential Amino Acid requirements for Clarias gariepinus. Diets 1–4 contained Albizzia seeds processed as follows: raw (D1), boiled for 15 minutes (D2), boiled for 30 minutes (D3) and boiled for 1 hour (D4). Water quality parameters: dissolved oxygen, temperature, pH, electrical conductivity and total dissolved solids were monitored and no mortality was observed during the experimental period. Growth and nutrient utilization indices: Mean Weight Gain (MWG), Specific Growth Rate (SGR%), Feed Conversion Ratio (FCR) and Protein Efficiency Ratio (PER) were calculated. The best growth and nutrient utilization values were observed in D4 with significantly higher (P<0.05) MWG and SGR. Growth performance of the juveniles increased as heat exposure time of the seeds increased. Fish fed D1(Control) showed a significantly (P < 0.05) lower growth performance, higher carcass nitrogen free extract and lower levels of crude protein when compared with all other dietary groups. The present study indicates that the inclusion of Albizzia seed meal (replacement of 50% of the total dietary protein of feed) after boiling for one hour significantly improved the growth performance and feed utilization of C. gariepinus juveniles compared with that of the raw seed meal. This investigation provided useful information on the chemical constituents of differently treated seeds of A. lebbeck and their incorporation into fish feed meals for Clarias gariepinus juveniles was recommended.en_US
