Insect meal as renewable source of food for animal feeding: A review

Abstract:

The massive utilisation in animal feeding of soy or fishmeal poses severe environmental issues. The insects could be a sustainable protein source. This article documents 150 species of insects that are currently commercially available in the EPPO (European and Mediterranean Plant Protection Organization) region and in North America. Furthermore, the various data regarding body composition are analysed. Amino acids and fatty acids of several insect species are compared with the composition of soy and fishmeal as principal protein sources for animal feeding. As a protein source, insects, depending on the species, have an adequate profile of amino acids. The more frequent limiting amino acids are histidine, lysine, and tryptophan, which could be incorporated into the diet. In conclusion, insects appear to be a sustainable source of protein with an appealing quantity and quality and acceptable nutritive properties. In conclusion, the use of insects as a sustainable protein rich feed ingbkp_redient in diets is technically feasible, and opens new perspectives in animal feeding. © 2013 Elsevier Ltd.
