Consequently, large amounts of feed proteins will be needed, and within this current global scenario soybean products are the main protein source in pig diets. Therefore, these act as a reference point, for the search of alternative sources that can help meet future protein demands. However, adequate feeding alternatives are still required. Algae production represents an acceptable alternative, as this type of aquatic biomass is able to develop under marginal land use. In addition, insects represent another potential alternative protein source considering that their larvae have a very quick development.
