AI Technical Summary
The application of existing cottonseed meal feed in monogastric animals and aquatic animals is limited, mainly because anti-nutritional factors and large molecular proteins are difficult to degrade effectively, and the efficiency of existing fermentation technology is unstable, making it difficult to achieve industrial production.
A ternary complex strain system of Aspergillus niger, Aspergillus oryzae, and Saccharomyces cerevisiae was adopted, combined with ammonium chloride and potassium dihydrogen phosphate as additives, and fermentation conditions were optimized to form a stable solid-state fermentation process, which achieved efficient degradation of cottonseed meal protein and removal of anti-nutritional factors.
It significantly improves the protein content and mineral utilization of small peptide cottonseed meal feed, degrades anti-nutritional factors, enhances the palatability and digestibility of the feed, completely removes free gossypol from the product, and increases fermentation efficiency by more than 30%.
