| Cattle have one stomach with four compartments, the rumen, reticulum, omasum, and abomasum, with the rumen being the largest compartment. |
| It is the digestive organ of the pile, the artificial stomach, the second omasum of the landscape's self-renewal process. |
| Suckling causes a reflex action bringing the walls of the reticulum together to form an esophageal groove leading directly to the omasum. |
| The rumen, reticulum and omasum can be compared to a kind of foregut fermentation chamber. |
| The omasum is almost absent in chevrotains. |
| Food taken into the rumen is later regurgitated into the mouth and completely masticated, then swallowed again and passed to the reticulum, omasum, and abomasum. |
