576 SWINE IN AMERICA 



It is said that an investigation made by a veterinarian 

 at the Indiana experiment station convinced him that 

 lodging- of the hulls in the throat or stomach, with re- 

 sultant irritation, choking, ulceration and perhaps blood 

 poisoning is what does the mischief. Pigs fed the plants 

 (li\'ested of bur hulls showed no ill effects. 



CANKER SORE MOUTH IN YOUNG PIGS 



Large water blisters appear about the mouth and 

 snout, rapidly succeeded by much heat and swelling of 

 the parts, and later thick brown scabs appear which open 

 into deep cracks. These scabs extend over the face, 

 head, and even to the body and limbs, the joints of the 

 latter becoming much swollen and inflamed. Ulcers 

 often form about the snout and jaws, eating the flesh 

 from the bone. There is dullness and a disinclination to 

 move, and often to suck the young pigs. The treat- 

 ment, which should be prompt and thorough, is a solu- 

 tion of permanganate of potash, using one ounce of the 

 crystals dissoh-ed in a gallon of water in a common pail. 

 In extreme cases, use two ounces to a gallon of water. 

 The young pigs should be dipped head foremost into the 

 solution and kept there for a brief time. Repeat this 

 two or three times, giving the pig time to catch its 

 breath in the intermissions. This treatment continued 

 for three or four days will usually efifect a cure, if the 

 disease is not of too long standing. Having successive 

 litters of pigs farrowed in the same pen should be 

 avoided where this disease has been prevalent, until the 

 pen has been thoroughly disinfected.
