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 eyes is of a gummy nature, which 
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.
