===Description===
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.
Impaction/obstruction of the oesophagus or 'choke' is the most common oesophageal disease of cattle and horses. Obstruction usuually occurs at the thoracic inlet, the base of the heart or the hiatus oesophagus of the diaphragm (i.e. the narrowest points). 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.
In cattle, choke usually occurs due to the consumption of large vegetables or fruit such as potatoes, turnips and corn cobs. Due to the indiscriminate nature of their feeding, cows may also develop choke due to ingestion of a foreign body.
