Which of the following is an example of a monogastric animal?

An example of a monogastric animal is primarily characterized by having a single-chambered stomach. Unlike ruminants, which possess multi-chambered stomachs designed for the fermentation and digestion of fibrous plant materials, monogastric animals typically have a straightforward digestive system that is more efficient for processing other types of food.

Dogs, as monogastric animals, have a simple stomach structure that allows them to digest a diet that is more varied, including both animal proteins and plant materials. Their digestive system includes a straightforward path from the stomach to the intestines, suitable for their omnivorous diet.

In contrast, cows and sheep are ruminants, equipped with complex stomachs that support the fermentation of grass and other high-fiber feeds, while horses, although not ruminants, are classified as non-ruminant herbivores; they have a unique digestive system tailored for processing plant materials effectively but still utilize a multi-part stomach system that differs from true monogastric digestion. This distinction is crucial for understanding the nutritional needs and digestive adaptations of various animal species.
