Study Notes
Monogastric Digestion Systems
- Non-functional caecum (appendix) is present in dogs, cats, rats, mice, pigs, and fish.
- These animals have a poor ability to handle fibrous foods.
- Digestion involves chemical action on food material.
Functioning Caecum - Hind Gut Fermenter
- Horse, rabbit, and guinea pig have a functioning caecum and enlarged colon.
- The caecum and colon contain micro-organisms that break down fibrous plant material through microbial fermentation.
- Absorption is low in these animals, requiring them to eat large quantities of food to obtain required nutrients.

- Caecum and colon are enlarged and contain micro-organisms to break down fibrous plant material through microbial fermentation
- Absorption is low, requiring animals to eat large quantities of food to get required nutrients
Ruminant Digestion Systems
- Multi-compartment stomach, e.g., four stomachs in sheep
- Ruminant animals, also known as "cud chewers", chew, regurgitate, and re-swallow food
- No upper front teeth in ruminant mouth, and no enzymes in saliva
- Examples of ruminant animals include cows, sheep, and goats
- Ruminant animals cannot tolerate too much grain in their diet, risking grain poisoning or acidosis
- High energy provision for ruminants must consider this risk

- Omasum: grinds roughage
- Abomasum: the only true stomach, functioning similarly to a monogastric stomach
