DISEASES OF SWINE 509 



tumor rather hemispherical in shape, red and slightly painful. 

 When exposed to the air for a time, it becomes swollen and darker 

 in color, and finally becomes dry and the surface cracked. In 

 time it will slough off. 



Treatment. Before replacing the prolapsed tissues, the mucous 

 membrane should be bathed with warm water for a few minutes in 

 order to reduce the inflammation and clean it. The protruded por- 

 tion can be replaced by pressing on it with the finger. If caused 

 by constipation a laxative of castor oil should be given and soft 

 food fed the animal. Sometimes the prolapse will again occur and 

 need to be replaced. If badly swollen, it is best to bathe it with an 

 astringent solution (five per cent alum solution). To retain it, a 

 stitch can be taken across the anal opening. If the protruded part 

 becomes injured or sloughs, it can be cut off and the margin of the 

 bowel sewed to the margin of the anus. (Ind. B. 100.) 



POISONS. 



POISONING BY MEAT BRINE. 



Meat brine and washing powders are the most common causes 

 of poisoning in swine, and are always accompanied by an inflamma- 

 tion of the intestines and stomach. Brine from meat barrels and 

 fish kegs is sometimes emptied where hogs have access to it and when 

 eaten will cause an intense inflammation of the stomach and in- 

 testines. Hogs will not eat too much salt if they have access to it 

 at all times, but the meaty taste of meat brine probably adds to their 

 desire for it, and is eaten in large quantities. 



Symptoms. These develop in a short time. The animal is 

 restless at first, will run from one place to another, lie down and 

 get up again, stamp the feet and squeal. Vomiting nearly always 

 occurs and a profuse watery diarrhea will come on if the hog lives 

 long enough. Convulsions occur, during which it will throw itself 

 around violently and froth at the mouth. The intervals between 

 the convulsions become shorter and shorter as death approaches. 

 The posterior parts are paralyzed and the animal will drag itself 

 from place to place. The duration of the attack varies from a couple 

 of hours to several days. The animal is sometimes suspected of 

 being mad unless the cause be known. 



Lesions. Upon post mortem the lining membrane of the 

 stomach and intestines is found loosened, sometimes in masses, and 

 there is intense congestion of the entire wall and the peritoneum in. 

 contact with it. 



Treatment. The hog should be given all the water it will 

 drink. Linseed oil in large doses can be given. Flaxseed tea is 

 also useful. To quiet the pain, at intervals, a teaspoonful of lauda- 

 num can be given. Treatment is seldom successful. (Ind. B. 

 100.) 



POISONING FROM WASHING POWDERS. 



It is a common practice to save the dish water as slop for pigs. 

 Hogs fed on such slops often sicken and die, the symptoms and
