Ruminants are a diverse group of herbivorous mammals characterized by their specialized digestive system, which allows them to ferment ingested plant material. This process, known as rumination, involves regurgitating partially digested food, rechewing it as cud, and then swallowing it again for further digestion. This adaptation is crucial for breaking down tough plant fibers like cellulose, which are difficult for most animals to digest.

The digestive tract of a ruminant is complex, typically featuring a multi-chambered stomach. The largest and most important of these chambers is the rumen, which houses a vast population of microorganisms, including bacteria, protozoa, and fungi. These microbes play a vital role in breaking down cellulose through fermentation, producing volatile fatty acids that the ruminant absorbs as its primary energy source.

Common examples of ruminants include cattle, sheep, goats, deer, giraffes, and antelopes. These animals are found in various habitats worldwide, from grasslands and forests to mountains and savannas. Their diets consist mainly of grasses, leaves, and other plant matter, and their digestive capabilities allow them to thrive on these abundant but fibrous food sources. The evolutionary success of ruminants is largely attributed to their efficient method of extracting nutrients from plant material, enabling them to occupy ecological niches that are inaccessible to non-ruminant herbivores.
