Cross-species summary: The abomasum is the fourth stomach in ruminants, often called the "true" stomach because of its structural and functional homology with the stomach of non-ruminants. Soon after parturition, the abomasum sometimes becomes distended either to the left (left abomasal displacement) or to the right (right abomasal displacement), resulting in anorexia and acetonaemia.

Species in which this phene is found:
taurine cattle (Bos taurus)
sheep (Ovis aries)
water buffalo (Bubalus bubalis)
