This study gives a comprehensive survey on 20 cows with vagus indigestion due to cranial functional stenosis (failure of omasal transport). The most important clinical findings were distension of the entire lateral abdominal wall on the left side and partially of the right ventral area as well, severely distended rumen, reduced or missing appetite and reduced defaecation. Nine animals had bradycardia. The dominant laboratory findings were increased concentrations of total protein and fibrinogen. Sixteen cows were slaughtered at the clinic. Six of these had signs of peritonitis in the cranial part of the abdomen, which had started from foreign body peritonitis. Six cows had abscesses between reticulum and liver, also starting from a foreign body, one cow had one isolated abscess in the liver and one cow severe fatty degeneration of the liver. In 2 cows no pathological changes could be found on the occasion of slaughter.
