How many stomach does a deer have?

Answer 1

Deer have four stomachs like all ruminants. There is the Rumen, the Reticulum, the Omasum and the Abomasum.

• The Rumen is a fermentation and storage vat. Micro-organisms break down a lot of food in the Rumen so it can be absorbed by the deer but it does not physically break down the food with acid like a human stomach.

• The reticulum is basically a filter that allows small particles to pass to the Omasum.
  

• The omasum acts like a sponge that draws off excess water before food is passed to the next step.

• The abomasum works like your stomach to break down food with acid so nutrients can be absorbed.
