40 DISEASES OF THE HOG. 
SIMPLE ULCERS OF THE STOMACH. 
I have met wth several cases of ulceratoin of the 
stomach of the pig as an independent disease and 
in conjunction with other diseases, such as hog 
cholera. In one well marked case, a fine sow, 
which had been in a thrifty condition until she was 
one year old, was noticed to vomit occasionally, 
and seemed to be somewhat uneasy after eating; 
this continued for several months and she began 
to lose flesh; and being a valuable sow I was called 
to see her. By this time some blood was mixed 
with the food in the vomit, and I diagnosed the 
disease to be either ulceration or cancer. I ex- 
amined some of the material vomited, but could 
not get any satisfactory results from it.

cases it may not be much affected. The animal 
will begin to eat its food with an apparent relish 
and all at once it will stop feeding, leave the 
trough, apparently in pain. It may vomit or seem 
to be trying to do so, something between a cough 
and an effort to vomit, and there may be only eruc- 
tions of gas. The animal soon gets into an un- 
thrifty condition; the bowels are usually confined 
and the urine scanty and high colored; the pulse 
and breathing are not affected in the early stages 
of the disease. If the animal is not relieved it . 
gradually becomes worse, vomits up nearly all its 
food, seems to be in much pain, and the contents 
of the stomach are usually mixed with blood. 
There is no other disease that can be mistaken for
