Insects or products derived from insects are considered as a valuable feed ingredient for aquaculture, poultry, and pigs but also exert possible secondary effects of health stimulators in livestock as reported in literature.Health benefits attributed to insects can create additional value in the insect chain. Three categories of bioactive compounds in insects are reported in this desk study: antimicrobial peptides (such as a-helical peptides, cysteine-rich peptides, proline-rich peptides, glycine-rich peptides), fatty acids (especially lauric acid), and polysaccharides (especially chitin and chitosan).
