Abdominal Ulcers

Predictive Values For Clinical Signs Of Abomasal Ulcer Disease In Adult Dairy Cattle

A 12-month prospective study was performed to determine the predictive values for clinical signs of abomasal ulcer disease in a hospital population of 296 adult dairy cows which were believed to have gastrointestinal dysfunction. There were 26 ulcer-positive cows (prevalence 8.8%). The occult blood test was a more reliable indicator of abomasal ulcer disease than were the abdominal pain or anemia tests. Only three ulcer-positive cows were negative for all three tests.
