Ruminants
Ruminant Physiology Facts
Unlike humans that have a simple stomach and only chew their food once, cattle have 4 stomachs. Like other ruminants (sheep, goats, elk, deer, etc.) cattle can eat their food hurriedly, then burp it up and rechew it more thoroughly later. The largest stomach, the rumen, acts as a fermentation vat to break down fibrous parts of forages that a simple stomach cannot digest.
