Corn bran is a by-product in the corn processing industry, especially in production processes such as starch and ethanol.

Although corn bran is generally seen as the outer layer of the corn grain, that is, the husk part, when it is considered as animal feed, it may contain different proportions of corn endosperm and corn germ depending on the production process.

Corn bran can be coarse or fine.

Corn bran, which is considered a protein-rich feed raw material, has a great importance in the nutrition of small cattle and poultry, especially dairy cattle and beef cattle.
