dc.description.abstractThe growth response ofC.gariepinus juveniles fed graded levels of boiledS. obtusifolia seed meal was studied for 84 days in a flow through system. The proximate analysis of Senna obtusifolia seed had 20.63, 6.81, 16.20, 4.52, 5.89 and 46.22% representing value for crude protein, ether extract, crude fibre, ash, moisture and nitrogen free extract respectively while anti-nutrient in seed were hydrocyanic acid, oxalate, phytate, saponnin and tannin with various concentration of 1.42, 2.64, 4.16, 0.96 and 2.44 mg/100g respectively. Six diet were formulated; which wereDiet D1 (Control: with 0% inclusion level boiled S. obtusifolia seed meal (100% soybean meal), D2 (10%), D3 (20%), D4 (40%), D5 (60%) and D6 with 100% inclusion level (total replacement of soya bean meal). The water quality parameters were monitored weekly and weight was taken every fortnight. The result showed that the best diet with boiled S. obtusifolia seed was D3as it gave the best MWG (13.83g), SGR (1.31), Protein Efficiency Ratio PER (1.34), profit index (2.28) and the lowest FCR (1.39) when compared with D2 (10%), D4 (40%), D5 (60%) and D6 (100%).The lowest growth and feed utilization parameters were observed in diet D6 with total replacement level. The condition factor (K) revealed that fish were in good condition throughout the period of study. The result of carcass composition showed all fish fed with experimental diet had an increase in carcass protein which ranged between (55.12-68.65%). The cost of feed production decreased with increase in inclusion level of S. obtusifolia seeds in the diets. The weight gain of fish also decreased with increase in S. obtusifolia seed replacement level above 20%. The use of S. obtusifolia seed at 20% inclusion level was the best because there was no significant difference between control diet D1 and D3 (P≥0.05).In conclusion 20% is the best replacement level for soybean meal with no deleterious effect on the growth of C.gariepinus juveniles. The use of S. obtusifolia seed at 20% replacement level for soybean is highly recommended in the diet of C. gariepinus juvenile.en_US
