98 Diseases of Cattle. 



LUMP JAW— CANCEROUS ULCERS. 



Lump Jaw is situated upon the jaws ; either upper or 

 lower, generally on the lower jaw. At first they appear as 

 small, movable, hard nodules. As they develop in size, they 

 become attached to the bone, and may continue to grow for 

 m.onths before breaking. When the ulcer breaks it has a 

 ragged appearance and discharges a thin liquid, or pus, and 

 sometimes bleeds profusely. As the disease advances, it af- 

 fects the teeth, causing them to fall out. 



TREATMENT :— Lump Jaw is incurable. Therefore, 

 there is no special treatment. When the nodule or lump 

 first appears, the animal can be marketed. But after the 

 lump has opened, the flesh should in no case ever be used. 



MAD STAGGERS. 



(Phrenitis.) 



Mad Staggers is an inflammation of the brain, and is 

 very similar to mad staggers in the horse. 



CAUSES : — Distention of the stomach caused by over- 

 feeding on long wet grass or clover. It is also caused by 

 an excessive accumulation of wax in the ear, which com- 

 municates with the brain. Injuries to the head, exposure to 

 hot sun, or may be the sequel to some fever. 



SYMPTOMS: — Mad Staggers more frequently occurs 

 during the heated term of the season. At the onset the ani- 

 mal appears stupid and dull, and is inclined to press its head 

 against some object. This is succeeded by quickened breath- 

 ing, excitement, and delirium. During these delirious at- 

 tacks, the eyes are bloodshot and staring, the animal run- 

 ning about as thoug-h it were blind and drunk or mad. If 

 the animal is not relieved it falls down in a state of stupor, 

 from which it never recovers.
