Generally, this is much less dramatic than a [[Gastric Dilatation and Volvulus|displaced stomach in the dog]], and develops chronically, although abomasal volvulus is a comparable condition.

The [[Abomasum - Anatomy & Physiology|abomasum]] is the fourth stomach of the cow and hangs loosely by the omentum. It can move from its normal position to left displacement where it becomes trapped under the rumen or a right displacement which may result in abomasal volvulus and torsion.

Rearrangement of abdominal viscera in pregnancy is thought to be an important aetiological factor, however reduced abomasal motility is thought to be the primary aetiological cause. Once the abomasum is displaced gas production by the organ continues causing distension and further displacement.
