Ruminants and Monogastrics

Ruminants are those animals that have a multiple-chambered stomach designed to digest herbaceous matter such as grass by the process of fermentation. Monogastrics are those animals that have a single-stomach that is designed for digestion of animal protein and highly-digestible phyto-nutrients such as fruits and grains. Questions about ruminants and monogastrics, including those about psuedo-ruminants (animals that have a single stomach like a monogastric but have their main fermentation vat in the cecum), can be asked and answered here.

Why are horses considered non-ruminant yet they feed on grasses?

Ruminants are animals that eat grass, regurgitate it as cud, rechew and then swollow it again for digestion. Cows are considered ruminants as they exhibit this behavior. Just because an animal eats grass it does not mean it is a ruminant.

Since horses do not regurgitate their feed and chew it again, they are not considered ruminants. Animals that eat a plant based diet are considered herbavores.

Why are poultry and swine collectively called non ruminants?

A ruminant is a mammal, of the order Artiodactyla, that digests plant-based food by initially softening it within the animal's first stomach, known as the rumen, then regurgitating the semi-digested mass, now known as cud, and chewing it again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called "ruminating". Poultry and swine are called non-ruminants because they do not ruminate.
