Performance features: The main purposes of microorganism fermented feed: Under artificial and controllable conditions, the equipment takes plant-based agricultural and sideline products as the main material and degrades some macromolecular substances such as polysaccharide, protein and fat. Then small molecular substances including organic acid and Soluble polypeptide are gen-erated to produce biological feed or raw material of feed featuring rich nutrition, good taste and high beneficial viable bac-teria content. That will the content of feed become rich, nutrient and accessible for animals to assimilate. Meanwhile, the equipment will produce quality raw materials of feed protein by utilizing cheap agricultural or light industrial by-products and achieve highly active beneficial organism through organism fermenting feed.
