Oesophageal obstruction in cattle is a more serious condition than in the horse. Obstructin may result in a failure to eructate, leading to the development of bloat. The clinical signs are similar to those seen in the horse including ptyalism, coughing, arching of the neck, dysphagia and nasal discharge. The expanded rumen may cause pressure on the diaphragm, reducing venous return to the heart causing respiratory distress or asphyxia.
