96 SHEEP DISEASES. 



at packing houses; the malady seems widespread 

 over the West. 



The lymphatic glands become caseous, and in 

 individuals where great enlargement has taken 

 place, emaciation is present. 



Treatment: Nothing but prevention is known 

 at the present time. 



13. Actinomycosis. 



Lumpy jaw; big jaw; wooden tongue. 



Cause: Actinomyces bovis, or ray fungus. 



Symptoms: Inability to chew food is the first 

 symptom noted, followed by a swelling on the jaw. 

 The tongue may be affected, and the animal suc- 

 cumb to starvation. It is a very rare disease in 

 sheep, but cases are on record. 



Treatment: None practical on the ranges, 

 Slaughter under government inspection is perhaps 

 the best method. Where but a single or at most 

 but a few individuals are affected on a small farm 

 the administration of potassium iodid may be re- 

 sorted to. 



14. Glanders. 



Sheep have never been known to become in- 

 fected through natural sources. This disease was 

 formerly confused with hemorrhagic septicemia, 



15. Contagious Abortion. 



Another disease seldom found in sheep. Usually 

 the form of abortion occurring among ewes is due 

 to toxic ingredients found in the food, or to ex- 

 posure and bruises.
