ABSTRACT
Fish meal is recognized as a valuable animal protein supplement and is added to feeds to obtain efficient diets. If aquaculture becomes an increasing contributor to human food supplies, it would mean replacing fishmeal with suitable plant-protein source. Cassava leaf meal has been a dietary protein source to both terrestrial and aquatic animal studies. Physical and sensory properties of feeds are necessary for transporting, assessing potential shell life, product attributes and acceptability. This study determined the effect on bulky density, water absorption index, texture and color of the developmental feed with the inclusion of different ratios of sun dried cassava leaf meal and fishmeal. There were three different proportions and each was manually pelletized. Sample pellets were specifically evaluated in terms of sensory properties and their physical properties were determined. The inclusion of different ratios of sun dried cassava leaf meal and fishmeal did not effect the texture and color of the three pellet samples. However, it lowered the water absorption index and bulk density of the pellets.
