Nutritional characteristics of biological fermentation of corn straw and its application in animal feed.

Corn straw is an important non-grain feed resource, which is not suitable for feeding animals directly because of its high crude fiber content. Biological fermentation technology can reduce the content of anti-nutrient factors in corn stalk, improve its nutritional value and feeding value, and is widely used in the chemical production in corn stalk feed because of its simple operation and green environmental protection. The bio-fermented corn stalk plays a significant role in regulating animal health and has a broad application prospect in animal breeding. The nutritional characteristics of corn stalk before and after biological fermentation, the methods of biological fermentation of corn stalk and its application in animal feed were reviewed in this paper to provide a reference for the rational application of corn stalk in animal production.
