NERVOUS DISEASES OF THE HOG. 



ENCEPHALITIS. 



The pig sometimes suffers with inflammation of the brain. 

 This occurs most frequently when running in pastures where the 

 grass is over-ripe. It may also arise from the effects of some nar- 

 cotic agent, or may be produced by tumors or abscesses forming 

 in the brain. 



Symptoms. — There will be marked dullness, increasing as the 

 disease progresses. The animal is excited by noise, the urine is 

 scant, and the bowels constipated. The pulse falls below normal. 

 The respirations are slow and usually stertorous in character. 

 The animal when standing hangs the head or rests the nose on 

 the ground; staggers, falls, and ultimately is unable to rise. 



Treatment. — But little can be done in this case. One drachm 

 of aloes should be administered. Twenty grains of the bromide 

 of potassium may be used. Belladonna tincture, in five-minim 

 doses, is an excellent remedy for inflammation of the brain in 

 hogs. 



EPILEPSY. 



This sometimes occurs in hogs, and is due to intestinal derange- 

 ment, such as worms, etc. 



Symptoms. — The patient gives way behind, begins champing 

 the jaws, froths at the mouth, and there is spasmodic jerking of 

 the head. The head is gradually raised as the fit comes on, and 

 finally the hog falls backwards on the ground, the attack lasting 

 for three or four minutes; after which he arises, and is appa- 

 rently well again.
