What animals have a modified monogastric?

Animals with a modified monogastric digestive system include pigs, horses, and some rodents. Unlike typical monogastric animals that have a single-chambered stomach, modified monogastrics possess adaptations that allow for more efficient digestion of fibrous plant materials. For instance, horses have a large cecum that serves a similar function to a ruminant's stomach by fermenting fibrous feed. This adaptation enables them to better utilize nutrients from their plant-based diets.
