Large Animal Digestion
Transcript of Large Animal Digestion
-Ruminants and Nonruminants Ruminants are multi- compartment
Their stomachs consist of four compartments. Non Ruminants -Horses and Hogs
-All parts are the same as the ruminant EXCEPT the stomach.
-N.R. stomach is a single compartment -Monogastric
Esophagus/gullet- tube like passage from the mouth to the stomach
Reticulum-catches liquids and foreign objects( wire and nails).
Rumen- the largest compartment;catches the solid foods.
Omasum-Strong muscle that grinds food sent from the rumen
Abomasum-this is the true stomach; contains digestive(gastric) juices and works the same as a Non ruminant.
Small intestine- long folded tube attached to the bottom of the stomach; aids further in the process of digestion
Large intestine- Larger in diameter than the S.I. but shorter in length. The end of the L.I. is the rectum
Cecum - "Blind gut" found where the small intestine meets the large intestine
- Has little function except in Horses, where it digests roughage through bacterial action. -Ruminants are multi compartment
-Their stomachs consist of four compartments.
Ruminants - Consist of Cattle, Sheep and Goats
They are cud chewers
They eat rapidly and through the intake of fiber, they bring their meal back up and chew it again.
This process takes place 8 –10 times a day.
Ruminants - Usually eat fibrous feeds like hay and pasture
Occasionally eat concentrates that are low fiber and high energy like grains and high protein foods
Let's get back to ruminants Cud Chewers? Ruminants eat rapidly; the animal then lays down and the food is forced back into the mouth where it is chewed again; this is known as their cud.
THE END Intestines:
Gastric juices contain enzymes: Pepsin and rennin
Both enzymes work in conjunction with the squeezing action of the stomach to digest the food
