High Concentrate/Low Fiber is best described for which diet type?

• A. Ruminant Diets
• B. Monogastric Diets
• C. Herbivore Diets
• D. Omnivore Diets

Answer: (B)

High concentrate/low fiber describes a diet that is dense in energy from easily digested carbohydrates like starches and sugars, with little fibrous material. Animals with a single-chambered stomach rely on enzymatic digestion in the stomach and small intestine, so they’re best suited to energy-dense feeds rather than fibrous forage. This fits monogastric species (such as pigs, dogs, and humans), which are optimized for processing concentrated carbohydrates rather than relying on extensive microbial fermentation of fiber. In contrast, ruminants depend on a multi-chambered stomach and microbial fermentation to extract energy from fibrous plant material, so high-fiber forages are more central to their diet (and excessive concentrate can disrupt rumen balance). That’s why the description pairs with monogastric diets.
