Nutritional evaluation of extruded faba bean (Vicia faba L.) as a protein supplement in cereals based diet in rats.

The quality of extruded faba bean (EFB) (Vicia faba L.) as a protein supplement in cereals diet was evaluated. Growth rate and protein efficiency ratio was better in 20% EFB blended dietary group of rats than those fed either on cereals alone or at 40% EFB supplementation. Subsequent studies on digestibility co-efficient, biological value, net protein utilization and net protein ratio also confirmed biological utilization of EFB proteins in a better way at low level (20%).
