Treatment. Prophylaxis. 761 



Prophylaxis. A rational plan of breeding must be adopted 

 and all pampering of the animals must be avoided. The great- 

 est care must be exercised in the matter of the purchase of 

 fresh animals as these may be the source of infection to the 

 whole flock. 



After symptoms have made their appearance it is a matter 

 of the greatest difficulty to check the spread of the disease. 

 The affected sheep and those that have been in immediate con- 

 tact should be isolated, and the remainder of the flock should 

 be removed to a high-lying district.
