Non-Ruminant Digestion
2
What are Non-Ruminants?

• Animals with digestive systems that have a simple
  stomach structure, also called a monogastric
  system
• Most animals are classified as omnivores or
  carnivores

The Non-Ruminant System

• Mouth
• Collects and chews feed and vegetation
• Teeth
• Carnivores
• Sharp teeth for tearing and ripping
• Omnivores
• Sharp teeth and flat molars for tearing and
  grinding

5
The Non-Ruminant System

• Salivary Glands
• Secretes digestive enzymes
• Provide lubrication for swallowing

6
The Non-Ruminant System

• Esophagus
• Connects mouth to stomach
• Unidirectional
• Forceful regurgitation may occur in some animals
  when sick

7
The Non-Ruminant System

• Stomach
• Glandular pouch that mixes and churns feed
• Secretes gastric juices and enzymes to aid in
  food particle breakdown

8
The Non-Ruminant System

• Pancreas
• Produces and secretes enzymes
• Aids in the digestion of carbohydrates and fats
• Liver
• Lobed reddish brown organ
• Produces bile (greenish in color)
• Aids in the digestion of fats
• Gall Bladder
• Storage sac for bile from liver
• Secretes bile into small intestine

9
The Non-Ruminant System

• Small Intestine
• Secretes intestinal juices
• Pale watery substance from the intestinal wall
• Protein digestion
• Buffers hydrochloric acid from the stomach
• Digests and absorbs nutrients

10
The Non-Ruminant System

• Small Intestine Sections
• Duodenum
• Secretion of intestinal juices, pancreatic
  enzymes and bile to further digest food
• Jejunum
• Digestion
• Absorption of nutrients
• Ileum
• Absorption of nutrients

11
The Non-Ruminant System

• Cecum
• Non-functioning blind pouch found in-between the
  small intestine and large intestine
• Large Intestine
• Absorbs water and adds mucus to undigested feed

12
The Non-Ruminant System

• Rectum
• Internal sphincter which controls excretion
• Anus
• External sphincter which controls excretion
