Wheat middlings are composed of which grain components and are mainly used in which type of diets?

• A. Endosperm, germ, and bran particles
• B. Only endosperm
• C. Only bran
• D. Only germ

Answer: (A)

Wheat middlings are a milling byproduct that includes all three primary grain components—the endosperm, bran, and germ—mixed together rather than representing a single part. Endosperm supplies starch and energy, bran provides fiber, and germ contributes fats, vitamins, and minerals. This combination makes middlings a versatile, energy-rich feed that can support growth and production without being as high in fiber as feeds consisting mostly of bran. For that reason, they are used mainly in monogastric diets, such as those for pigs and poultry, where energy and digestibility are prioritized. They are not simply endosperm, or only bran, or only germ, which is why the correct description includes all three components.
