Growth and feed utilization in Clarias gariepinus fingerlings fed on Acacia auriculiformis leaf supplemented diets

Effect of ‘Earleaf’ plant (Acacia auriculiformis) as feed additive was examined on Clarias gariepinus fingerlings (4.2±0.5 g) over a period 56 days against farm-made feed which served as the control. A. auriculiformis leaves were collected, air-dried (under shade), powdered and added at varying inclusion levels (0, 0.5, 1.0, 1.5 and 2.0) % to basal diets containing 40 % crude protein. Fish were randomly distributed into...
