CON, H20, H40 and H60 represent 0%, 20%, 40% and 60% inclusion of H. illucens larva meal, respectively; BIO is a commercial diet (BioMar Inicio, Brande, Denmark). SD, standard deviation, SEM, standard error of the mean; DM, dry matter; CP, crude protein; EE, ether extract; OM, organic matter; GE, gross energy. Different letters within a row indicate significant difference (p ≤ 0.05). * Statistical analysis did not include BIO.
