Impaction/obstruction of the oesophagus or 'choke' is the most common oesophageal disease of cattle and horses.  

Impaction/obstruction of the oesophagus or 'choke' is the most common oesophageal disease of cattle and horses. The most common sites of obstruction are the '''thoracic inlet''', '''the base of the heart''', and the '''hiatus oesophagus''' of the diaphragm. In horses, causes of choke include consumption of unsoaked sugarbeet, rapid ingestion of roughage (hay), indadequate mastication of food, or rarely the ingestion of a foreign body (e.g. corn cob). Horses that are poorly fed or have poor dentition are more prone to the condition.
