An example of a non-ruminant herbivore is a horse.
Non-ruminant herbivores are animals that have a simple stomach and cannot efficiently digest tough plant materials. Instead, they rely on microbial fermentation that occurs in their large intestine to break down fibrous plant materials. Horses are an example of non-ruminant herbivores as they have a single-chambered stomach and a relatively small, simple cecum (a pouch that connects the small and large intestine) where microbial fermentation occurs.
In contrast, ruminant herbivores, such as cattle, sheep, and goats, have a complex, multi-chambered stomach that allows for more efficient fermentation of plant materials. Therefore, horses, being non-ruminant herbivores, have a different digestive system than cattle, sheep, and goats, making them an example of a non-ruminant herbivore.
