174 VETERINARY STUDIES 



After trimming and cleaning, some cases are well treated, by 

 swabbing freely with lysol, or full strength sheep dip, or some 

 other disinfectants, and then drying and applying a powder 

 like scarlatone, or compound alum powder or calomel. 



It is sometimes advisable to use a roll of tar-soaked oakum, 

 pressed well up between the toes, and held in place by a tar 

 bandage around the foot. Where new tissue seems to grow 

 too rapidly, it may be repressed by means of small pads of 

 oakum or tow, soaked with tar and bandaged firmly over the 

 part that needs checking. 



For astringent effect upon the granulations, tincture chlorid 

 of iron, full strength or diluted as indicated to one fourth with 

 water, may be used. Four per cent carbolic acid in tar is very 

 useful, especially as it tends to keep out dirt and foreign matter. 



Lip-and-Leg Ulceration 



In this disease of sheep we again have local necrosis as the 

 chief characteristic. This disorder may occur in conneccion with 

 foot-rot. 



Symptoms. — The chief symptom of this trouble is the ulcers 

 upon the skin most commonly of the legs, or upon the mouth 

 parts, especially lips and muzzle. The ulcers have dry crusts 

 with a granulating surface beneath. They may invade the 

 mucous membrane of the mouth or nostril, or even of the eye. 

 There is often a considerable slough and an offensive odor. 

 Some cases are slight and chronic ; others, more severe. 



Treatment. — Scrape off the dead and the spongy tissue, then 

 apply to the diseased area either zinc chlorid or silver nitrate, 

 10 per cent in water, and repeat three times a week, or second, 

 use an ointment of vaseline or lard, one hundred; sulphur, 10; 

 any good dip, five. Under good treatment prognosis is 

 favorable. 



Canker Sore Mouth (Stomatitis) 



Canker sore mouth is also due to B. necrophorus, affects 

 young pigs as a rule and older shoats occasionally. It is a 

 troublesome, difficult disease to manage after there has been a 

 general spread of the virus. Ground surfaces, floors, bellies of 

 brood sows, etc., soon become contaminated with the infection. 

 Many cases occur during the teething of young pigs.
