518 DISEASES OF CATTLE, SHEEP, GOATS, ETC. 



should be hand treated and the affected parts curetted and properly 

 drained. If the lesions are on the coronary band or hoof, all the 

 diseased or loosened portions should be removed with the knife. 

 As in everything else, diligence and careful attention are necessary 

 for successful results in these stubborn cases. 



Treatment of the venereal form especially demands this care- 

 ful handling. The penis of the bucks, if found diseased, should 

 be forced out of the sheath and the necrotic patches cautiously 

 cauterized with the zinc chloride or nitric acid solution previously 

 mentioned, and dressed daily by injecting a 1 per cent sheep-dip 

 solution, a 1 to 500 permanganate of potash solution, or a 25 per 

 cent solution of peroxid of hydrogen into the sheath until cured. If 

 the penis or inner part of the sheath is extremely ulcerated and the 

 prospects of cure is not favorable in a reasonable time the animal 

 should be killed. Lesions on the external part of the sheath are 

 treated like similar lesions on the lips and legs. All the tags of 

 filthy wool should be removed, and if the lesions are mild, treat 

 with mild antiseptics every two or three days ; if severe or chronic, 

 cauterize first and then dress with mild antiseptics three times 

 weekly. Care must be observed, however, not to overdo the cau- 

 terization on this part, as closure of the orifice of the sheath is 

 liable to occur as a result of too vigorous treatment, and a severe 

 inflammation and swelling of these parts may take place. The 

 same strength injections of sheep dip, peroxid of hydrogen, or po- 

 tassium permanganate, as above mentioned, may be used in the 

 vagina of the ewes, and the external lesions treated the same way 

 as those on the sheaths of the bucks and wethers. 



At times an infection with the necrosis germ is seen in the 

 form of abscesses containing semisolid pus and spoken of by shep- 

 herds as boils. These are very easily cured by opening them with 

 a knife, cleaning out the pus, and applying the disinfectant and 

 antiseptic solutions already referred to. 



The warty lip form of this disease, as already mentioned, runs 

 a course to recovery under favorable conditions in about three to 

 four weeks, but medicinal treatment will materially aid recovery 

 and prevent some of the cases from becoming malignant or chronic 

 with more or less loss of tissue from ulceration. The application 

 of lard, mutton tallow, or vaseline containing 5 per cent of a rec- 

 ognized sheep dip has been very beneficial after rubbing off the 

 scabs and crusts that form around the margins of the lips and nos- 

 trils. The necrosis germ being one which thrives best without 

 oxygen, exposure to the atmosphere will of itself prove beneficial. 

 Pure strength coal-tar dips, peroxid of hydrogen, tincture of iodin, 

 and 1 per cent pyoktannin have all been found efficient, but the 

 milder remedy just before recommended has given the best results. 

 The lesions of the lining membrane of the mouth, which some- 

 times accompany this disease of lambs, may be satisfactorily treated 

 by washing the mouth with a 2 per cent chlorate of potash solution, 

 a 3 per cent boric acid solution, or a 1 per cent creolin solution.
