Abomasum is the so-called 4th stomach of ruminating animals; more correctly, the 4th compartment of the ruminant stomach. It is also called the ‘true’ or ‘rennet’ stomach, and the ‘reed’. It is an elongated, pear-shaped sac lying on the floor of the abdomen, on the right-hand side, and roughly between the 7th and 12th ribs.

Synonym: Tympanitic Resonance in Cattle
Right-side tympanitic resonance (ping) caused by gas distention of intra-abdominal structures was diagnosed in 366 adult cattle, in a USA study. The source of the ping was identified as the abomasum in 137 animals, various segments of the intestinal tract in 157 and peritoneal gas in two. The source of the noise was not identified in 70. The principal final diagnoses were: left displacement of the abomasum, right displacement of the abomasum, abomasal (and omasal) volvulus, other gastro-intestinal conditions and non-gastrointestinal conditions.
