1 Animal Anatomy and Physiology Part 2 By : ARI WIBOWO, S.Pt.,M.Si & SUHARDI, S.Pt.,MP
2 Digestive System Ruminant System Rumen Largest compartment Food is soaked, mixed. Microorganisms ferment the feed. Carbohydrates are absorbed by the papillae. Small fingerlike projections that aid in absorption
3 Digestive System Ruminant System Reticulum Hardware stomach Due to large mouth they collect hardware Wire form fence Rocks Etc
4 Digestive System Ruminant System Reticulum Secretes mucus Honeycomb shaped Traps hardware from traveling to the rest of the digestive system.
5 Digestive System Ruminant System Reticulum Regurgitation Packs feed into an egg shaped ball to be rechewed. (CUD)
6 Digestive System Ruminant System Omasum Size of a quarter to enter. Round Soccer Ball Many Folds Like a round book Grinds the food as it passes through.
7 Digestive System Ruminant System Abomasum True stomach Functions the same as the monogastric Intestines are the same as monogastric.
8 Digestive System Function: Animal takes in food Digested in to a form that the body can use. Basic elements Oxygen, Iron, Potassium, etc
9 Pathway of Digestion 1. Food enters the mouth and swallowed down the esophagus. 2. Food enters the rumen and starts to digest by micro-organisms. 3. Food is regurgitated back to the mouth and is chewed (Called a Cud). 4. Chewed food is then swallowed into the reticulum. 5. Food then goes into the omassum or true stomach.
10 6. Food then passes into the abomasum. 7. Food enters the small intestines where valuable nutrients are absorbed. 8. Any food that is not absorbed enters the large intestines for more absorption. 9. All un-absorbed feed is then passed to the outside through the rectum.

21 Indicator: Poultry Digestive System
22 Species of Poultry Chicken Turkey Goose Duck Pigeon Peacock
23 Poultry Digestive System The digestive system is somewhat different from mammals. The mouth lacks teeth and lips. Instead, the beak serves to bite off food. Barbs on the tongue help food to be moved backwards, so it can be easily swallowed. The esophagus forms a pouch, called a crop, where food is stored for brief time periods.
24 Poultry Digestive System From the crop, food moves down into the true stomach, or proventriculus, where hydrochloric acid and pepsin starts the process of digestion. Next, food moves into the gizzard, which is oval shaped and thick walled with powerful muscles. The chief function of the gizzard is to grind or crush food particles - a process which is aided by the bird swallowing small amounts of fine gravel or grit.
25 Poultry Digestive System It is written that the muscles of a turkey s gizzard can crush a hickory nut, which requires 75 kg mechanical pressure! From the gizzard, food moves into the duodenum. The small intestine is similar to mammals, there are two blind pouches or ceca, about 4-6 inches in length at the junction of the small and large intestine.
26 Poultry Digestive System The large intestine is short, consisting mostly of the rectum about 3-4 inches in length. The rectum empties into the cloaca and feces are excreted through the vent.
