Wheat bran is often fed to horses in a warm mash, but horse owners may not be as familiar with other byproducts of wheat milling. Wheat byproducts were an integral part of the beginning of the feed industry. Many of the earliest feed companies were flour milling companies looking for an outlet for their byproducts. Since wheat byproducts are so important to the feed industry, it is essential that proper terminology be used to differentiate between the various types of byproducts.
Wheat bran is the coarse outer covering of the wheat kernel that is separated from cleaned and scoured wheat in the usual process of commercial milling. Wheat middlings, known also as wheat midds, refers to the fine particles of wheat bran, wheat shorts, wheat germ, and wheat flour produced in the milling process. Wheat midds must be obtained in the usual process of commercial milling and must contain no more than 9.5% crude fiber.
