  1. Livestock Digestive Systems

  2. Ruminant Digestive System • Objectives: • Know the four parts of the ruminant stomach. • Know examples of animals that have a rumen. • Be able to describe the function of all four of the parts of the ruminant stomach.

  3. What are some animals that have Rumens? • ?

  4. Cattle

  5. Sheep

  6. Goats

  7. Deer

  8. Elk

  9. What do all of these animals have in common? • They all live off of grass, and other roughages.

  10. Cellulose Lignin Why can’t we live off of the same things cows eat?

  11. How can a Ruminant digest these things? • Through the process of rumination • Eating rapidly, regurgitating and masticating their feed. (Chewing their cud) • With specialized structures in their stomach • Ruminants have microorganisms living in them that break down cellulose for them and make those nutrients absorbable.

  12. What are these four structures?

  13. Rumen • Large fermentation vat • Microorganisms break down cellulose • Creates lost of gases (methane) • Ruminants have to be able to eructate (belch) • Some nutrients are absorbed • Roughages are reduced in size

  14. Gas Today’s Hay Yesterday’s Feed Rumen Feed Storage

  15. Rumen (Punch)

  16. Reticulum • Collects objects that shouldn’t be in the digestive system. • Nails • Screws • Baling wire • Magnets are placed into many dairy animals reticulums.

  17. Reticulum (Hardware Stomach or Tripe)

  18. Omasum • Works to remove water from the food • Absorbs fatty acids

  19. Omasum (manyplies)

  20. Abomasum • Glandular Stomach (like yours) • Secretes digestive juices. • Breaks down food stuff further for absorption. • Absorbs some nutrients.

  21. Abomasum (True Stomach)

  22. Order that food moves. • Rumen • Reticulum • Omasum • Abomasum Hint to remember Alphabetically back-words. Ru Re O A

  23. Review Give me an example of an animal that has a rumen? Name the four compartments of the ruminant stomach? What does a rumen help and animal break down that we can’t? What are the common names of the four parts of the ruminant stomach?

  24. Nice Work!Now on to the assignment!
