Fermentation-special peanut meal is a safe and stable fermented product produced using peanut cake meal as the main raw material, adopting a solid-state mixed fermentation method combining microbial strains with compound enzyme preparations. The solid-state mixed fermentation removes aflatoxin B1 from peanut cake meal, improves product safety, increases in vitro protein digestibility, increases small peptide content, and improves product palatability. It is beneficial for animal digestion and absorption, increases beneficial metabolites (lactic acid, antimicrobial peptides, etc.), helps improve the micro-ecological balance of animal intestines, promotes the reproduction of beneficial microorganisms, inhibits the growth of harmful bacteria such as E. coli and Salmonella, enhances immunity, and reduces disease incidence. Overall, fermentation-special peanut meal is a safe, nutritious, versatile and environmentally friendly feed raw material.
