The feed needed in animal husbandry is a particularly important part. There are many ways to process animal feed, among which the hydrolysis and fermentation of animal feed have many important uses. During the fermentation process, microorganisms will use the nutrients in the feed for metabolic activities to produce a variety of beneficial metabolites, such as vitamins and organic acids, thereby increasing the nutritional value of the feed. The fermentation of microorganisms can also decompose difficult-to-digest substances such as cellulose and hemicellulose in the feed, and convert them into sugars and proteins that can be absorbed and utilized by animals, thereby increasing the energy and protein content of the feed.
