Distiller's grains are rich in nutrition, containing a variety of organic compounds, B vitamins and cellulose, and are good raw materials for edible fungi cultivation. As long as a proper amount of auxiliary materials are added to the distiller's grains, it can be suitable for the growth of various edible fungi. It can not only reduce the production cost of edible fungi, but also solve the problem of environmental pollution.

Distiller's grains are rich in crude protein and crude fat, and have high heat energy. The crude protein content is 54% higher than that of Miao, and the crude fat is 38% higher than that of corn. In addition, due to the proliferation and accumulation of microorganisms during koji-making and fermentation, the composition and types of amino acids in protein are relatively balanced and basically complete. The mineral content in distiller's grains is also very rich, and the content of major trace elements such as calcium and iron is more than 10 times higher than that of wheat and corn. Nowadays, distiller's grains are widely used as livestock feed in rural areas, and a large number of egg whites have not been transformed, which is difficult to be absorbed and utilized, resulting in great waste. Using distiller's grains to make compound feed is an economical and effective method to improve the titer and make it better digested and absorbed. According to different livestock and poultry feeding standard, additives such as trace elements can be added to make different compound feeds.
