Abstract

The effect of supplementing soya bean meal with feather meal was investigated to determine diet acceptability and growth performance of Heteroclarias species. The fishes were divided into six treatment groups containing three fishes per replicate basin. The groups were control (0% FEM), 2.5% FEM, 5% FEM, 7.5% FEM, 10% FEM and 12.5% FEM. Acceptability was calculated using the ‘‘time to strike index’’. The weight and length of fishes were measured weekly. The specific growth rate, food conversion ratio, condition factor and percentage weight gain were derived. There was no significant difference (P>0.05) in acceptability in all the dietary types. The increase in weight and length in all dietary types was not significantly different (P>0.05). There was also no significant difference (p>0.05) in SGR, FCR and K- Factor in all dietary types at the end of the study. Increasing levels of feather meal inclusion within the diets reduced the percentage weight gain. Only catfishes fed 12.5% FEM differed significantly (P<0.05) from the control (0% FEM). The results suggest that feather meal can replace up to 10% of soya bean meal in diets for Heteroclarias species.
