The stomach of a ruminant occupies ¾ of the abdominal cavity

The stomach of a ruminant occupies ¾ of the abdominal cavity Rumen This is the first compartment of a ruminant animal. Most feed collects here after being swallowed. Cellulose is broken down here with the help of rumen microbes. http://www.extension.umn.edu/distribution/livestocksystems/components/DI0469-02.html
