Cotton seed hulls are classified as:

• A. Dry roughage
• B. High-energy concentrate
• C. Forage silage
• D. Protein supplement

Answer: (A)

Cottonseed hulls are a dry roughage: they’re a fibrous, low-energy byproduct from cottonseed processing that mainly provides bulk in the diet rather than substantial energy or protein. Because they are high in crude fiber and low in digestible energy and protein, they fit with other dry roughages used to fill the rumen and promote chewing rather than supply high-energy or protein needs. They are not a high-energy concentrate, since energy-dense feeds (like grains) provide much more readily digestible energy. They are not forage silage, because hulls aren’t fermented forage stored as silage. And they’re not a protein supplement, since their protein content is low.
