left displacement of the abomasum

left displacement of the abomasum
(LDA) displacement of the abomasum of a cow to the left, underneath the rumen, with abomasal atony, usually soon after birth of a calf. It may be due to previous pressure from the gravid uterus or to abomasal distention from a high-grain diet. Symptoms include anorexia, drop in milk production, and ketosis.
