Soybean Meal Fermented with Bacteria Increases the Protein Content of Shrimp Feed


From Abstract: This study aimed to improve the nutritional value of soybean meal (SBM) in shrimp (Penaeus vannamei) by fermenting it with Bacillus subtilis E20.  The protein content and B. subtilis E20 proliferated significantly as the initial moisture increased from 30% to 50% during fermentation.  Compared with SBM, the protein content of the fermented soybean meal (FSBM) increased by 19%, accompanied by an increase of 18.75% in the total hydrolyzed amino acids.  The free amino acid profile and content in FSBM also increased by 374.9% compared with SBM.  The FSBM is a good substitute for fish meal (FM) in a diet with 37% protein and 7% lipid content.  The maximal replacement levels of FM in shrimp diets with SBM and FSBM were 37.42% and 61.67%, respectively, based on the estimated feed efficiency.  The B. subtilis E20-FSBM can be a potential protein source used as a replacement for FM in shrimp diets.
