Obstruction of the Gullet— Choking. 



This may occur in the pharynx, but generally in the oeso- 

 phagus or gullet. It is usualy caused by the lodgment of food. 

 It is rarely seen in sheep as compared with the ox, but may occur 

 where roots are being fed. 



S)»mptoms. 



The sheep stops feeding, the breathing appears difficult, the 

 animal commences to bloat, the swelling appearing greater in the 

 region of the left flank than in the right. Death frequently 

 occurs, due to suffocation from pressure of the distended stom- 

 achs on the diaphragm or midriff, which diminishes the capacity 

 of the chest cavity, preventing free expansion of the lungs, the 

 -derangement of the pneumogastric and sympathetic nerves from 

 the irritation also helping to cause a cessation of the vital func- 

 tions.
