Biological method uses microbial fermentation technology to make fermented feed. This treatment process generally has a long cycle and requires The process of selecting and managing bacterial strains is complex. The Chinese invention patent CN02155417. The raw materials and swill materials are mixed and inoculated with yeast and microbial strains controlled by the mixing of the flow controller, and then solid fermentation is carried out in batches under computer control, and then dried, ground, tested and packaged to make a high-calcium multi-dimensional yeast protein feed.
