What Are Ruminant Animals?

Ruminants are animals or mammals that regurgitate the food from the stomach and chew it again. Ruminants are mostly herbivorous. The animals have a multi-chamber stomach structure which facilitates four main processes, that is, regurgitation, remastication, resalivation and re-swallowing.

Examples of ruminant include:

  • Cattle
  • Sheep
  • Goats
  • Buffalo
  • Deer
  • Elk
  • Giraffes
  • Camel

What You Need To Know About Ruminant Animals

  • Ruminant animals have a multi-chamber stomach structure which facilitates four main processes, that is, regurgitation, remastication, resalivation and re-swallowing.
  • Ruminants are mostly herbivorous.
  • Ruminants have a complex stomach with stomach compartments namely Rumen, Reticulum, Omasum and abomasums.
  • Reverse peristalsis is common in ruminants.
  • Ruminants have a long digestive system.
  • Ruminant animals do not produce enzymes for protein digestion.
  • Ruminant animals produce more saliva with no carbohydrate digestive enzymes.
  • Ruminant animals have a large liver when compared to non-ruminants animals.
  • Ruminant animals digest all plant carbohydrates including cellulose.
  • Ruminants have two blunt canines.
  • The premolars and molars of the ruminant animals move in lateral direction.
  • Ruminant animals undergo regurgitation.

What Are Non-Ruminant Animals?

Non-ruminants also referred to as monogastric-animals have uncomplicated or a simple stomach structure which facilitates the normal digestion process where the ingested food is digested in a single process. Non-ruminants can be herbivorous, omnivorous or carnivorous.

Examples of non-ruminant include

  • Humans
  • Primates
  • Swine
  • Dogs
  • Cats
  • Fowl
  • Rabbit
  • Horses

What You Need To Know About Non-Ruminant Animals

  • The animals have uncomplicated or a simple stomach structure which facilitates the normal digestion process where the ingested food is digested in a single process.
  • Non-ruminants can be herbivorous, omnivorous or carnivorous.
  • Non-ruminants have a simple stomach with only one compartment.
  • Reverse peristalsis is absent in nonruminants.
  • Nonruminants have a short digestive system.
  • Nonruminant animals produce enzymes for protein digestion.
  • Nonruminant animals produce less saliva with carbohydrate digestive enzymes.
  • Nonruminant animals have a relatively small liver compared to that of ruminants.
  • Non-ruminants digest carbohydrates except cellulose.
  • Non-ruminant animals have four sharp canines.
  • Premolars and molars of ruminant animals move in vertical direction.
  • Nonruminant animals do not undergo regurgitation.
