Name one ruminant animal.

• A. Pig
• B. Dog
• C. Cow
• D. Horse

Answer: (C)

Ruminants digest fibrous plant material through microbial fermentation in a four-chambered stomach, which includes the rumen, reticulum, omasum, and abomasum, and is often accompanied by cud-chewing to break down tough fibers. Among common farm animals, the cow exemplifies this system, efficiently digesting grass and hay through this specialized stomach. In contrast, pigs and dogs have a single-chambered (monogastric) stomach, relying on enzymatic digestion, and horses, while grazing animals, are hindgut fermenters where most fermentation occurs in the cecum and colon rather than in a four-chambered stomach. So the cow is the best fit for the concept of a ruminant.
