The [[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 displcement where it becomes trapped under the rumen or a right displacement which may result in abomasal [[Volvulus, Intestinal|volvulus]] and [[Torsion, Intestinal|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.

==Diagnosis==

Diagnosis is made on history and clinical signs in combonation with auscultation findings. Using a stethoscope the entire left and right flank should be percussed. Over the region of displacement a distinct ping will be heard.  Once a ping is identified the stethoscope shoud be held over that area whist ballotment of the lower flank, this creates a splashing sound at the gas fluid interface which is heard as a tinkle. This confirms the presence of a displaced abomasum.

Conservative medical management can be attempted in low value animals.

Rolling

Rolling can be undertakne to try and manipulate the abomasum into the correct position. This technique involves casting the cow onto her right side and rolling her over whilst percussing and balloting the pings to track the movement of the gas filled abomasum.  Success rates with this are usually 30-50%.
