536 DISEASES OF SWINE 



soured slop, which irritates the mucous membrane and produces 

 a stomatitis. In these cases it is usually associated with disease 

 of the stomach and bowels produced by the same irritating toxic 

 substances. 



Inflammation of the mouth may result from burning of the 

 mouth by eating food which is too hot. Where ground foods 

 are cooked and fed hot, care must be used not to have them 

 too warm at time of feeding. Stomatitis may also occur as the 

 result of combining irritating drugs with the food, such as lye 

 or copperas. These agents are frequently given on the farms for 

 the purpose of ridding the animals of worms which are beUeved to 

 be present. The results are often very disastrous. 



• Another not infrequent cause of stomatitis, or sore mouth, is 

 the careless handling of disinfectant solutions about the barnyard. 

 Often where solutions of carbolic acid or corrosive sublimate are 

 handled, they are carelessly spilled on the ground after being 

 used. If a hog is present in the barnyard he will invariably come 

 and wallow in the artificial mud-hole made by the bucket of dis- 

 infectant solution. He will also usually drink a certain amount 

 of the fluid, and not infrequently will have, as a result, a sore 

 mouth for several days. In some cases the results are even more 

 severe, and an inflammation of the stomach and bowels may be 

 the result. 



Hogs which are allowed to run in filthy wallows frequently de- 

 velop a sore mouth as a result of the poisonous molds and germs 

 developed in the stagnant waters. Another source of danger 

 in these hog wallows is drainage from old manure piles. The 

 seepage from these manure piles contain a large amount of am- 

 monia and other irritating substances, and hogs that are allowed 

 to drink water from a wallow which receives drainage of this kind 

 are always likely to develop a sore mouth and even more severe 

 infections of the stomach and bowels. 



Decomposing and rotten food is another source of chemical 

 irritants that often set up a stomatitis. Milk of animals that have 

 diseased udders is commonly fed to hogs. This milk is just as 

 dangerous to the hog as it is to the human being. The germs 

 present are likely to cause stomatitis, or disease of the stomach, 

 with vomiting and diarrhea. Molded silage, poisonous weeds,
