What are the names of the cow’s stomachs?

Beef cattle are ruminants and ruminants have one large stomach with four compartments. Those compartments are the rumen, the reticulum, the omasum, and the abomasum.

  • The rumen is the largest of the three compartments and contains microorganisms that help digest what the animal eats.
  • The reticulum is lined with cells that look like a honeycomb and if a cow happens to pick up a small nail or hardware in their feed the material ends up in the reticulum.
  • The omasum has cells that shape into a leaf and the omasum empties into the abomasum.
  • The abomasum functions very much like our stomach.
