    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.
