The abomasum hangs loosely by the omentum, it can move from its normal position to left displcement where it becomes trapped under the rumen or a right displacement  Occurs most frequently in heavy yielders on high concentrate diets and in late pregnancy.  

The [[The Abomasum - Anatomy & Physiology|abomasum]] hangs loosely by the omentum, it can move from its normal position to left displcement where it becomes trapped under the rumen or a right displacement  Occurs most frequently in heavy yielders on high concentrate diets usually in the first 6 weeks of gestation. Sometimes cases do occur before calving this is in late gestation and accounts for 5% of cases.

** Rearrangement of abdominal viscera in pregnancy is thought to be an important aetiological factor.

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 factor. Once the abomasum is displaced gas production by the
