  1. Ruminant and Pseudo- ruminant By Rachel Footit and Rebecca Groves

  2. What is a Ruminant animal? • It is an animal that has 4 compartments in their stomach. • It contains a rumen, reticulum, omasum, Abomasum. • These are found in cattle, sheep, goats, and chickens. • These help brake down lots of food when the animals eat.

  3. The Rumen • It’s about 60% of the stomachs. • It is also has bacteria and other microbes that promote fermentation. • Food will leave the rumen and get regurgitated for about 15 minutes and swallowed to the reticulum, then it will be a repeating process for about 2-3 hours.

  4. The Reticulum • The 2nd stomach in the system. • It looks like a honeycomb. • It helps keep the food in the Rumen mixed with water and saliva. • When that is done the mixture can move on to the other parts of the system.

  5. The Omasum • It looks like pages to a book. • It absorbs many of the nutrients broken down in the reticulum and rumen. • It removes excess water from food. • It reduces the size of food particles before passing them to the Abomasum for digestion by enzymes

  6. Abomasum • It’s last compartment of the stomach system. • It breakdowns the majority of the chemicals in the food. • It also mixes in digestive enzymes • The only one having glands that discharge acids and enzymes for digestion.

  7. What is a Pseudo- Ruminant animal? • They contain 3 compartments in their stomachs. • These animals do not regurgitate or ‘chew the cud’ • These animal are still similar to ruminant animals but don’t get the most nutrients out of leafy materials. • Pigs, rabbits , llama, horses, and alpaca are the most known animals to be pseudo-ruminant.

  8. How are the two different? • Pseudo- Ruminant animals just have a large cecum and doesn’t regurgitate their food. • Ruminant animals have a rumen and do regurgitate all their food they intake.

  9. Parts of a Pseudo-Ruminant • There is several parts of the stomach. • There is a large Cecum, and a large intestine.

  10. What is a Cecum? • Helps digest plants in the body. • It absorbs water and salts from undigested food. • Has a muscular wall that kneads the contents to speed up the absorption. • This show that the feeds nutrients is not absorbed as much as an animal with a rumen.

  11. The Large Intestine • It is made up of mostly colons: ascending colon, transverse colon, sigmoid colon. • It actively transport sodium, and absorbs water by osmosis. • It holds an environment where bacteria can grow and reproduce. • It will eliminate all waste, undigested, and unabsorbed material to leave the body.
