DIGESTIVE SYSTEM 81 



The affected animals refuse to eat, and although they frequent 

 the drinking trough, they actual^ drink very little. There is a 

 frothy, ill-smelling discharge from the mouth. There may be a rise 

 in tsmperature of frcm one to three degrees Fahrenheit. The treat- 

 ment consists of mouth washes of antiseptics, frequently applied. 



Vesicular and ii'.ceratire stomatiUs is enrusd by the same agencies 

 and presents lesions similar to vesi;'ular cheilitis, and will not be 

 further dis.'ussed. 



Necrotic stomatitis is not uncommon, particularly in suckling pigs. 

 The further discussion of this condition will be foimd under the 

 topic, Necrobacillosis. 



Symptoms. — As above indicated, the symptoms of stomatitis of 

 the various types vary onlj- in intensity. There is more or less sali- 

 vation and drooling, champing of jaws, and evidence of difficulty 

 in mastication. On inspection the lesions will be evident, which are 

 usuall.v sufficient upon which to base a diagnosis. 



Treatment. — The treatment also varies with the type of inflam- 

 mation. In all instances the cause should be removed, and in the 

 infectious types there should be topical application of some suitable 

 antiseptic. 



EPJZ:X)T]C APHTHAE 



Foot-and-mouth disease of swine is manifested primarily by lesions 

 of the feet, but the buccal mucous membrane and skin of the snout 

 may be involved. The mouth lesions consist of vesicles of the mucous 

 membrane of the lips and mouth. The vesicles vary in size and 

 are usually of short duration. There will invariably be involvement 

 of the coronary bands and a general systemic disturbance which 

 will be sufficient evidence for differential diagnosis. A general 

 description of this disease will be" found in the chapter on infective 

 diseases. 



SCUEVV 



This is a disease manifested by ulceration and hemorrhage of 

 the gums, unthriftiness, and debility. It is of rather common occur- 

 rence in young pigs. 



Etiology. — There appears to be no specific exciting cause of this 

 condition. However, it usually occurs in pigs that are improperly 

 fed, kept in insanitary quarters, or in pigs produced from continued 

 inbreeding. 



Lesions. — Scurvy is characterized by progressive ulceration of the
