There are two manifestations of [[The Abomasum - Anatomy & Physiology|abomasal]] displacemet. In both the [[The Abomasum - Anatomy & Physiology|abomasum]] becomes trapped between [[The Rumen - Anatomy & Physiology|rumen]] and abdominal wall. The more comon presentation is the left displacement (LDA) which is Ventral and to the left of [[The Rumen - Anatomy & Physiology|rumen]].

*# '''Ventral and to the left of [[The Rumen - Anatomy & Physiology|rumen]] (LDA)''' - the more common presentation.

[[The Abomasum - Anatomy & Physiology|Abomasal]] atony and increased gas production leads to displacement. This can be induced by the combination of a high concentrate diet,ketosis, hypocalcaemia and increased [[Volatile Fatty Acids - Anatomy & Physioogy|volatile fatty acids]] from the [[The Rumen - Anatomy & Physiology|rumen]]. A displacement to the right an RDA is less common.

Additionally the [[The Abomasum - Anatomy & Physiology|abomasum]] may rupture, causing peritonitis, shock and death.
