Displaced abomasum is a common disease in high producing dairy herds. If undiagnosed or complications from surgery should result and death occurs, naturally the loss can be very significant.
Low quality feeds, lack of bunk space and lack of fresh feed.
Rapid change in dry, pre and post partum rations. Ketosis, Metritis, or any disease that affects feed intake. Cows with milk fever and retained placenta are all good candidates for DA's because of decreased energy and dry matter intake, less rumen fill which reduces fore stomach and abomasal mobility. Genetic traits for high production increase the preponderance of DA's. Increase in the hormone estrogen occurs before calving, which can reduce feed intake.
