DISEASES OF THE HOG. 223 



Symptoms: The sudden death of one or more 

 hogs calls the attention of the swine grower to the 

 fact that something serious is the matter with his 

 pigs (alhough other diseases may have caused 

 this). In the early stages of the disease the pig is 

 noticed to be dull, will neither seek food nor water; 

 it likes to hide itself, lies down most of the time, 

 its head is low and the ears will be lopped; often 

 the signs of pain will be well marked by the con- 

 stant movements of some parts of its body, or the 

 first symptoms may be cough with a little dis- 

 charge from the eyes and nose, the exudation from 

 the lids of the ej^es is of a gummy nature, w^hich 

 sometimes glues the edges of the lids togther so 

 firmly that the animal cannot open them; at this 

 stage of the disease the appetite may not be in the 

 least impaired. I have made post mortem exami- 

 nations in .this form of the disease and, notwith- 

 standing the animal having a good appetite, I have 

 found well marked ulcer tufts in the large intes- 

 tine. It lies mostly on its breast and abdomen and 

 may remain in the position for hours if not dis- 

 turbed. In some cases there will be violent vomit- 

 ing and the brain becomes affected and the animal 

 may become frantic, or it may lie in an unconscious 

 state until it dies. In the early stages of the dis- 

 ease the feces are normal, but very soon a very 

 foetid, black or dark diarrhea sets in. The pulse 

 rises to one hundred to one hundred and twenty- 

 five per minute, and the heart beats are barely 

 perceptible. There is a peculiar spasmodic breath- 

 ing in all cases where the lungs become congested.
