Catarrhal Gastritis in Swine. 173 



hyperthermia, stiffness, tenderness of the abdomen to handling, 

 arched back, a disposition to hide under the straw, plaintive 

 grunting when roused, drooping of the tail. The tendency is to 

 a rapid recovery after'the evacuation of the stomach by vomiting, 

 though it may persist under a continuance of the irritating 

 ingesta. 



In these last cases the lesions may closely resemble those of the 

 contagious affections of the abdomen, but the disease may be dis- 

 tinguished by its indisposition to spread beyond the herd which 

 is subjected to the unhealthy dietary. 



Treatment. Change the diet to one of pure and easily digesti- 

 ble materials, soups, mush, fresh whey or buttermilk, boiled 

 farinas or flax seed, and even fresh grass. If there is violent 

 diarrhoea boiled milk is often of great value. 



Whatever food is given should be furnished in a vessel into 

 which the animal can't get his feet, as these are usually charged 

 with septic germs which are pathogenic to the diseased stomach, 

 though they may have started from ordinary saprophytes. 



For the same reason it is usually desirable to change the pen, 

 as the animal grubbing in the ground charges the snout with 

 the same offensive microbes. 



If vomiting is not already established, 30 grains of ipecacuan 

 may be given, or tepid water may be used to assist the process. 

 If constipation is present 10 to 30 grains of calomel (according 

 to size) may be given. In case of diarrhoea a combination of 

 calomel 1 part and chalk 12 parts, may be given in 3 grain doses, 

 two or three times a day. Or x / 2 to 1 drachm nitrate of bismuth 

 may be substituted. 



Cleanliness in food and surroundings is among the most im- 

 portant measures, and if the skin has been filthy, repeated washing 

 with soap and warm water may be resorted to with great benefit.
