286 THE DISEASES OE CATTLE. 



THE GAD-FLY 



Is very different from the warble-fly. It pierces the 

 skin, sncks the blood and causes great pain. (Gresswell.) 



Remedy. — Rub with a mixture of 4 oz. of flowers of 

 sulphur, 1 gill spirit of tar, and 1 quart of train oil ; or 

 a mixture of spirit of tar, linseed oil, sulphur, and car- 

 bolic acid. 



FOUL IN THE FOOT 



Is usually caused by dampness and is greatly aggrava- 

 ted by dirt and cold. It may, however, be caused by 

 injuries to the hoof or surrounding parts. Fetid dis- 

 charges often issue from the cleft of the hoof. Parts of 

 the hoof may come off, leaving an exposed, bleeding sur- 

 face, which may suppurate and even ulcerate. Fungoid 

 granulations may arise and involve the foot and heel. 

 The fetlock may swell and the general health be affected. 

 The horn, if growing irregularly, may split, or it may 

 cause rupture of internal tissues. 



Remedy. — Care and cleanliness; place on level floor, 

 with slight backward slope of course. Pare diseased horn 

 and apply linseed poultice. Purge if necessary. Apply 

 any of these ointments : 



1. Carbolic acid, 4 drams, lard, 4 oz. 



2. Boric acid, 1 part, lard, 7 parts. 



3. Sulphate of copper, finely powdered, 1 part, alum, 

 finely powdered, 1 part. 



4. Nitrate of copper, 1 part, tar, 6 parts. 



Wrap hoof with antiseptic tow or lint. For a list of 

 antiseptics, see page 31. 



FOUNDER 



Is uncommon, nor is it of much importance in the ox. 

 Purge; rest; cold water applications; salines. 



Loss of a hoof may arise from other causes than foul 

 or founder (laminitis), as, for example, catching the foot
