DISEASES OF SHEEP AND GOATS 215 



ciated, anemic, mucous membranes of the eyes, moutli 

 and nose become very pale and the sheep die in convul- 

 sions from suffocation. 



Pkeventive Treatment : Avoid grazing your sheep on 

 low marshy soil, especially during warm wet weather. 

 Young lambs and weak ewes are especially susceptible to 

 this disease. 



Medical Treatment: The writer has tried various 

 treatments as fumigation with different substances and 

 injection of remedies into the windpipe by the use of a 

 hypodermic syringe, etc., but none have proven very suc- 

 cessful, from a practical standpoint. I would recommend 

 placing the affected animals in a tightly closed barn or 

 shed, in the center of which place a pan of red hot coals 

 and cover with Sulphur. 



A person should remain in the barn or shed as long as 

 he possibly can and after the fumes become so irritating 

 that he cannot endure them any longer, he should im- 

 mediately make his exit. The sheep should be compelled 

 to stay a minute or two longer and then quickly open 

 the doors and windows. Eepeat this treatment once or 

 twice a week. Feed affected animals well. Give them 

 fresh water to drink and protect them from exposure. 

 This treatment, as above described, has given very good 

 results, providing the parasites were not too numerous. 



SCAB 



(Mange) 



Cause : The mange mite (Psoroptes Communis) . This 

 parasite is equipped with stylets which pierce the skin 

 at the seat where the mange mite penetrates the skin, 

 and produces small red spots followed by a blister filled 

 with serum, which ruptures, the serum drying and form- 

 ing a small scab. It is in this way that innumerable 

 mange mites cause the piling up of scabs thus producing 

 a very scaly condition. As Mange advances, the scaly
