Detailed Description
Fermented soybean meal powder is a high-protein feed ingredient produced by the combined fermentation of beneficial microorganisms—including Bacillus subtilis, lactic acid bacteria, and yeast—using premium-quality soybean meal as the raw material. It represents a functional upgrade over traditional soybean meal. Its core advantages lie in the elimination of antinutritional factors and the enhancement of nutrient utilization: during the fermentation process, antinutritional factors such as trypsin inhibitors, urease, and oligosaccharides in soybean meal are thoroughly degraded, thereby preventing issues like bloating and diarrhea in animals after consumption. At the same time, large-molecule soybean proteins are broken down into smaller peptides and free amino acids, increasing the digestibility and absorption rate by 20% to 30% compared to conventional soybean meal, making them readily available for direct absorption by young animals. Moreover, the probiotics and their metabolic byproducts remaining after fermentation help regulate the balance of the animal’s intestinal microbiota, boost immune function, and reduce the need for antibiotic use. Additionally, the mild fermented aroma enhances feed palatability, encouraging higher feed intake in animals.
Fermented soybean meal powder can be categorized into solid-state fermented soybean meal powder and liquid-state fermented soybean meal powder, depending on the fermentation process. Among these, solid-state fermented products are more widely used in the market due to their simple production process and moderate costs. They are highly adaptable to various aquaculture, livestock, poultry, and pet farming scenarios, and can replace 20% to 50% of fishmeal or conventional soybean meal. This not only reduces feed formulation costs but also enhances the growth performance and product quality of farmed animals. As such, it has become one of the key raw materials driving the feed industry’s transition toward green and efficient practices.
