The nutritive value of soybean meal (SBM) in piglets can be increased through bacterial fermentation as antinutritional factors, such as antigenic proteins, that pose challenges while weaning are degraded. Bacillus subtilis BS9 and B5 ferment SBM with high efficiencies, decreasing antigenic high-molecular weight proteins and increasing soluble proteins, under conditions that reduce fermentation costs. In early weaning piglets, BS9 fermented SBM meal did not improve the ADG, ADFI, and FCR from day 1-14, however, FCR improved significantly from day 15-28.
