Optimization of a hatchery residue fermentation process for potential recovery by black soldier fly larvae.

ABSTRACT: The conventional management of hatchery residues (HR) poses environmental issues and health risks for handlers. This study evaluates the potential of fermentation to reduce pathogens and odors in HR, enabling them to be recovered into feed using black soldier fly. This saprophagous edible insect is valued for its ability to efficiently bioconvert organic residues into high-quality biomass. Due to the low carbohydrate content of HR, whey permeate was added at lactose inclusion levels of 0, 5, 15, 25, and 35% (dry basis) to optimize fermentation. Using a commercial ferment starter culture (0.3%, wet basis), HR were fermented under semi-anaerobic conditions for two weeks. Fermentation metrics, including pH, microbiological loads (total aerobic mesophilic, presumptive lactic acid bacteria, col
