Abstract

The use of grain waste in BSFL cultivation technology represents an innovative approach aimed at increasing sustainability and improving the economic performance of agribusinesses. The aim of the study was to compare the effects of different feed mixture compositions on the chemical composition of BSFL and to assess their nutritional potential for producing protein meal from dried biomass. The experiment was conducted under laboratory conditions, cultivating BSFL on a grain mixture (GM) and grain waste (GW). The final analysis demonstrated that larvae grown on GW are a more efficient option in terms of biochemical value and nutritional potential. They provide maximum protein content and a sufficiently high amino acid ratio, making them a food source for farm animals and a substitute for traditional feed. The obtained results open up prospects for using agricultural waste for the sustainable development of larval cultivation technologies and the creation of environmentally friendly and cost-effective methods for producing high-quality feed.
