Surgical correction of a displaced abomasum (DA). The cow was draped to expose the right paralumbar fossa (see image). The abomasum was sutured in a corrected position, and the incision was closed. DA surgery has a success rate of 75-95%. To avoid surgery, a displaced abomasum in some cows may be corrected by casting the cow on her right side and rolling her through a 70 degree arc, although recurrence is likely. As the abomasum is loosely suspended by the omenta in the abdominal cavity, it can move from its normal position and block passage of ingesta. DA occurs in up to 20% of cows, often associated with high concentrate rations or rations with finely chopped forage. The incidence of DA is reduced by feeding total mixed rations with adequate forage, thereby avoiding separate concentrate feeding.
