However, antinutritional factors (ANFs) such as glycinin, β-conglycinin, phytate phosphorus, and neutral detergent fiber (NDF) restrict its use in piglet feed. Our lab has previously isolated a thermophilic strain of Bacillus licheniformis (B4) that displays high enzymatic activity and probiotic potential. The aims of this study were to evaluate B4’s ability to reduce ANFs in a lab-scale SBM fermentation and to assess B4 fermented SBM’s (B4-FSBM) influence on piglet growth performance. Fermentation resulted in significant decreases in NDF and phytate phosphorus by 27.0% and 59.2%, respectively. Additionally, large antigenic proteins were broken down successfully, and crude protein increased by 5.0% (P < 0.05). The feeding trial showed that piglets fed B4-FSBM experienced significant improvements in the gain to feed ratio during week 4, and higher apparent digestibility of crude protein during weeks 3-4 when compared to the negative control.","abstract_html":"Soybean meal (SBM) is the primary protein source in swine diets.
