Left and right displaced abomasum (Farmer Factsheet)

Contributor(s): Polly Gratwick , Keith Cutler

  • Displacement of the abomasum is a commonly seen condition in dairy cattle and can have a significant impact on herd productivity.
  • Usually referred to as an LDA (left-displaced) or RDA (right-displaced), the term describes the movement of the abomasum out of its normal position either to the left or right hand side of the cow's abdomen.
  • LDAs are seen more frequently than RDAs.
