  • 6. Digestion <ul><li>Ruminants : Have a four compartment stomach vs. one of the monogastric (ex. humans, pigs) </li></ul><ul><li>The four compartments are: RUMEN, RETICULUM, OMASUM, ABOMASUM. </li></ul><ul><li>The stomach of a ruminant occupies ¾ of the abdominal cavity </li></ul>Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 7. Rumen <ul><li>This is the first compartment of a ruminant animal. Most feed collects here after being swallowed. Cellulose is broken down here with the help of rumen microbes. </li></ul>http://www.extension.umn.edu/distribution/livestocksystems/components/DI0469-02.html Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 8. Rumen <ul><li>On left side of the animal </li></ul><ul><li>Largest part of the stomach, makes up 80% of the stomach </li></ul><ul><li>Lighter feed collects here (cellulose) </li></ul><ul><li>Absorbs nutrients </li></ul><ul><li>Requires a lot of water </li></ul>Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 9. Reticulum <ul><li>Second compartment of the stomach </li></ul><ul><li>There are many folds and its nickname is honeycomb </li></ul>http://education.vetmed.vt.edu/Curriculum/VM8054/Labs/Lab21/Lab21.htm Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 10. Reticulum <ul><li>Hardware stomach -Traps any foreign material that the animal may picks up. It is very thick and therefore harder to damage. Stores foreign objects so that damaging items do not go through the digestive tract. </li></ul><ul><li>Honeycomb shape </li></ul><ul><li>Helps open and close rumen, makes up 5% of the stomach </li></ul><ul><li>Absorbs nutrients </li></ul>Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 11. Omasum <ul><li>Third chamber of the stomach </li></ul><ul><li>Nicknamed manyplies </li></ul>http://education.vetmed.vt.edu/Curriculum/VM8054/Labs/Lab21/Lab21.htm Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 12. Omasum <ul><li>Right side of animal, makes up 8% of the stomach </li></ul><ul><li>Called manyplies because it looks like pages of a book </li></ul><ul><li>Absorbs nutrients </li></ul>Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 13. Abomasum <ul><li>Fourth compartment of the stomach </li></ul><ul><li>Where true digestion occurs </li></ul>Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 14. Abomasum <ul><li>On right side of animal, 8% of stomach </li></ul><ul><li>Enzyme activity breaks down feed </li></ul><ul><li>Nickname: True stomach </li></ul>Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 15. Small Intestine <ul><li>Upper part of the intestine where digestion is complete and nutrients are absorbed into the body </li></ul><ul><ul><ul><li>Long in length, about 150 feet long </li></ul></ul></ul><ul><ul><ul><li>Aids in further digestion after feed goes through the stomach </li></ul></ul></ul>http://www.bioschool.co.uk/bioschool.co.uk Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 16. Large Intestine <ul><li>Goes from the ileum to the anus and includes the cecum, colon, and rectum. </li></ul><ul><ul><ul><li>Absorbs water </li></ul></ul></ul><ul><ul><ul><li>Some vitamins and minerals are also absorbed here </li></ul></ul></ul>Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 17. Aids in Nutrient Absorption <ul><li>Rumen Microbes- Bacteria or protozoa live in stomach and help breakdown feed </li></ul>http://res2.agr.ca/lethbridge/emia/TEMproj/rumenbac_e.htm Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 18. Aids in Nutrient Absorption <ul><li>Saliva- helps protect the stomach by acting as a buffer. Contains alkaline which helps maintain the rumen microbial. </li></ul><ul><li>Pancreas- helps breakdown fat by secreting enzymes. </li></ul><ul><li>Liver- Contains bile which helps digest fat. </li></ul>Compilation: AECD, California || For more veterinary stuff visit www.techyvety.com
  • 19. Keys for Digestion <ul><li>Nutrients : Digestion helps animals obtain nutrients from their feed. This is important for many reasons: </li></ul><ul><ul><li>Growth </li></ul></ul><ul><ul><li>Maintenance </li></ul></ul><ul><ul><li>Production (making of milk) </li></ul></ul><ul><ul><li>Reproduction </li></ul></ul>http://office.microsoft.com/clipart/results .
