Fermented soybean meal (FSBM) has been widely investigated as a nutritional strategy for reducing the use of fish meal (FM) and antibiotic growth promoters. Microbial fermentation by using bacteria can increase the bioavailability of nutrients and reduce the levels of antinutritional factors in soybean meal (SBM).
