606 EPITOME OF MODERN TREATMENT 



Rot in Sheep, Distomiasis. See Liver'Rot. 

 Roup. See Laryngitis, Diphtheria, Croup. 



Saddle Galls. 



Avoid friction and undue pressure of badly fitting harness, and heavy- 

 cloth or felt linings. Use only harness linings of light leather. Treat at 

 first with wet dressing of two parts of saturated boric acid solution and 

 one part alcohol on aseptic gauze, covered with oil silk blanket and surcingle. 

 Treat inflamed sebaceous follicles as advised for acne (see Acne). Islands 

 of necrotic tissue, or sitfasts, must be removed by the knife. To the re- 

 maining wound apply balsam of Peru and aseptic dressings, or an astringent, 

 stimulant and antiseptic powder. 



Sand Crack. Quarter-Crack. 



Prophylaxis: — Avoid weakening the foot by paring away sole and frog, 

 and thus putting all the horse's weight on wall of foot. Occurs in inner 

 quarter of fore foot; in toe of hind foot. Remove the shoes, and pare thin 

 the edges of the fissure. Apply flaxseed and bfan poultice mixed with 2 

 per cent, creolin, and rest, to relieve the inflammation. After the inflamma- 

 tion has passed, treat the crack by either removing a V-shaped piece of 

 horn; by paring away the upper portion of crack to sensitive laminae and 

 coronary band above, and clamping the crack below; or by grooving the 

 wall above at right angles with the crack. All these measures tend to im- 

 mobilize the edges of the crack and allow of formation of new horn. To 

 stimulate growth of horn, also blister the coronet. Apply bar shoe, with thin 

 heels and side clasps in fissure of toe; a three-quartered bar shoe in quarter- 

 crack. Employ covering of wood tar on hoof continuously. 



Sarcoma. 



Use knife freely and try Coley's mixture of toxins of erysipelas and B. 

 prodigiosus. At times successful in human practice. 



Satyriasis. See Sexual Excitement. 



Scab in Sheep. 



Due to Dermodectes communis, var. ovis. Lambs and yearlings most 

 susceptible. 



Segregate and dip newly-bought sheep. Isolate sick and disinfect prem- 

 ises and contaminated objects. Shear sick and remove crusts with soft soap 

 solution (1 to 50), aided by brush. Treatment is done with baths or dips. 

 They are given only four hours after feeding and at body heat. Repeat 

 dip in ten days and keep animal in bath two minutes. Dip head under 

 once, in sulphur dip; keep mouth, nose and eyes out in poisonous (tobacco, 

 arsenical) dips. For shorn sheep, use U. S. Bureau of Animal Industry 

 dip which is cheap, safe and efficient. Flowers of sulphur, 24 lbs.; unslaked 

 lime, 8 lbs.; water, 100 galls. Mix lime in box with water to make paste; 

 sift on sulphur; stir all well together. BoU with 25 galls, of water for two 

 hours or longer, till solution of chocolate-liver color and sulphur mostly 

 disappears from surface. Settle mixture in a barrel with bunghole four 

 inches from bottom; allow four hours for settling. Draw off only clear 

 liquid into dipping vat and add water to make 100 galls. For animals in 

 full fleece, use manufactured tobacco, 1 lb.; flowers of sulphur, 1 lb.; water, 

 5 galls. Soak tobacco 24 hours or more, on night before dipping, boil 

 tobacco solution for a minute and allow tobacco to remain in it over night. 

 Mix sulphur to paste with water in a pail. Strain liquid from tobacco by 

 pressure, and add liquid to sulphur paste and enough water to make 5 gal- 

 lons. After dipping, turn sheep into clean yard. Dip apparently healthy 

 sheep first; then scabby ones, when a flock is attacked. There are many 

 excellent commercial dips on the market; follow specific directions with eacli. 

 Other agents include: creolin, 2 gallons; arsenic, 1.5 lbs.; iron sulphate, 10 

 lbs.; water, 100 gallons, etc. Good pasturing and generous feeding aid re- 

 sistance against scab.
