746 INDEX OF DISEASES AND REMEDIES 



BOIL or FURUNCULUS continued. 



Laxative diet, alkaline sulphites and chlorates, and calcium sulphide 

 internally. 



When opened, treat antiseptically. 



Arsenic internally sometimes prevents recurrence. 

 BONE SPAVIN. See SPAVIN. 



BOTRYOMYCOSIS. 



A local disease of horses and sometimes of cattle and pigs, caused by 

 a fungus, the Botryomyces equi. Infection leads to formation of 

 cutaneous or subcutaneous suppurating growths of variable size, 

 hard, movable, and not very painful ; occur on shoulder, withers, 

 jaw, scrotum, sheath, tail, etc. ; sometimes inside the body. 

 Early excision ; pot. iodide administered daily for a month or longer. 



BOTS IN HORSES. 



Larvae of oestrus equi developed in stomach. 

 Turpentine and oils, bitters, hydrochloric acid, iodine, naphthol, copper 



and iron sulphates, arsenic, followed by purgatives. 

 Carbon bisulphide 75 grains, in gelatin capsule, repeat dose in twelve 



hours, and next day give a dose of physic. 



Green fodder ; destroy larvae as they are expelled in spring, and the fly. 

 BOWELS, INFLAMMATION OF. See ENTERITIS. 

 BRAXY IN SHEEP. 



An infective gastro-enteritis characterised by patches of inflammation 



and ecchymoses chiefly affecting the mucous and serous membranes 



and skin. Pathology undetermined. (Consult Report by Dr. 



Hamilton on Braxy and Louping-Ill, Board of Agriculture and 



Fisheries, 1906.) 



Most cases prove fatal. 



Prevent by carefully regulated dietary. 



Removal from exposed, undrained, infected grazings. 



BROKEN KNEES IN HORSES. 



Where skin not broken, tie up head and apply diluted zinc or lead 



acetate solution for two or three days. 



When skin cut, cleanse thoroughly, dress antiseptically, bring edges 

 together with pin sutures, plaster, styptic colloid, or shellac paste ; 

 retain them in position with light calico bandage ; dress with mild 

 astringent solutions. 



When skin considerably lacerated, the tendon and its sheath bruised and 

 exposed, or the knee-joint opened, the limb should be put in splints 

 and animal in slings ; several folds of antiseptic lint, retained in place 

 by a calico bandage, over which cold water is made to trickle con- 

 tinuously. 



When tendon much bruised, knee-joint laid open, bones seriously 

 injured or fractured, anchylosis must ensue, and the animal had 

 better be destroyed. 

 BROKEN WIND IN HORSES. 



Pulmonary emphysema, associated with indigestion and characterised 

 by expiratory dyspnoea and peculiar cough. Of nervous origin and 

 connected with the vagus. 



Seldom curable, but relieved by careful dietary; good concentrated 

 food given damped ; feed and water frequently, in small quantity at 

 a time, but withhold before hard, fast work. 



Reasonable restriction of water specially needful when heart affected. 

 Laxatives and salines given occasionally. 

 Rock salt, chalk, or whiting in manger. Two or three ounces linseed 



oil in the food twice a week. 

 Arsenic (Fowler's solution) given daily or every second day, may be 



continued for months. 

 Sedative cough balls occasionally.
