How can crop residues be classified in feedstuffs?

• A. Concentrate feed
• B. Roughage or energy feed
• C. Mineral supplement
• D. Protein supplement

Answer: (B)

Crop residues are fibrous, bulk feeds that provide roughage to ruminant diets and help maintain rumen function, while offering relatively low energy compared with concentrates. This makes them best described as roughage, with only modest energy value, so the category “roughage or energy feed” fits. They are not concentrates, mineral supplements, or protein supplements, which is why those options don’t apply. Examples include straw, corn stover, and other crop stalks or husks, all of which serve mainly to add fiber and bulk rather than high-energy or protein content.
