NECROTIC STOMATITIS OF PIGS 407 



Diagnosis. — ^The diagnosis is not difficult, and depends upon 

 the fact that in this disease well marked, thick, necrotic areas 

 and deep ulcers occur upon the mucous membranes in the 

 regions noted. In no other disease of the calf are these 

 deposits so marked. 



Couise. — ^The disease, if left to itself, in most cases leads to 

 death in five to eight days. Some individuals may live as 

 long as three weeks and then die of pneumonia. Cases which 

 recover, do so very gradually, convalescence lasting for weeks. 

 The healing of the ulcers is an extremely slow process. 



Prognosis. — Calves affected with necrotic stomatitis if left 

 to themselves usually die, or if they recover, remain per- 

 manently stunted in growth. On the other hand, if proper 

 • treatment is administered early, most of them recover, 

 healing requiring about two weeks. 



Treatment. — ^The treatment consists in thorough cleansing 

 and disinfection of the mouth cavity. Twice daily the mouth 

 should be syringed out with a 2 per cent, creolin solution in 

 warm water. The patches of necrosis may be scraped off or 

 curetted away in so far as this is feasible. After the sores 

 are irrigated, it is recommended to cover them with a paste 

 made of one part salicylic acid and ten parts glycerin applied 

 with a stick or brush. Lugol's solution of iodin is also recom- 

 mended. The calf may be allowed to suck its mother, or if 

 a weanling, should be fed liquid food, best milk. Plenty of 

 cool water should be kept within reach. 



Prevention.- — ^The sick calves should be separated from the 

 healthy ones. The mouths of exposed calves should be 

 examined once daily for lesions of necrotic stomatitis. Dis- 

 infection of the stalls, pens, buckets, etc., should be made, 

 using a 3 per cent, creolin solution.
