No difference in protein quality was noted between three species of earthworms, as evaluated by net protein utilization and relative nutritive values in growing chickens. Similar growth responses per g nitrogen intake were obtained for the earthworm meals, a broiler starter diet and a commercial fish meal sample. The results thus indicate that no harmful substances which might have had a depressing effect on the utilization of amino acids, accumulated in the bodies of the earthworms.
