dc.description.abstractAn investigation of 84 days feeding trial was carried out to examine the effect of replacing the dietary soybean meal with Senna occidentalis seed meal on the growth performance, nutrient utilization, carcass composition, haematological indices and cost benefit of Heteroclarias fingerlings. Five iso-nitrogenous diets were formulated with Senna occidentalis seed meal replacing 100, 75, 50, 25, and 0% soya bean meal in the diets. The result shows fermented S. occidentalis seed had 91.58, 2.155, 14.35, 3.515, 3.64 and 29.7 g/100g dry matter, ash, crude fibre, ether extract, nitrogen free extract and crude protein, respectively while alkaloid, saponin, tannin, phytate, oxalate and flavonoids were in concentrations 5.45, 3.71, 8.50, 2.51, 5.60, 9.8 mg/g-1with 12.10, 19.35, 7.61, 20.32, 25.12, 11.71% respectively. Fermentation significantly increased the crude protein content of the seed while the anti-nutritional were all reduced. The results showed significant difference (p<0.05) in weight gain, SGR, FCR and PER between treatments. The results revealed that the best diet was the control diet which gave the mean weight (337.13g), standard length gain (15.31cm), total length gain (16.19cm), specific growth rate (1.38 %days), nitrogen metabolism (910.02), survival rate (100%) and net profit (N39.47) compared to other diets. The crude protein of the fish carcass ranged between 50.37 and 55.05 g/100mg compared to the initial of 49.99 g/100mg. The result of the haematology revealed the best result for PCV (41.67%), Hb (13.87g/dl), TRBC (6.93%) and MCHC (30.00%) when the fish was fed with 0% S. occidentalisseedmeal. Cost of feed production decreased with increase in inclusion level of fermented S. occidentalis seed meal in the diets. The use of S. occidentalis seed meal at 0% (control diet) level of replacement gave the best. Thus the use of S. occidentalis seed at 0% replacement level of soya bean seed is recommended in the diet of Heteroclarias fingerlings.en_US
