The diseases of sHEEf . 285 



Sheep do not suffer from tuberculosis, at 

 least tJie disease is exceedingly rare among 

 sheep in America or elsewhere. 



In truth, of the long list of diseases usually 

 catalogued as occurring in sheep the shepherd 

 will not in his lifetime observe more than one 

 or two, always excepting the diseases that come 

 from internal or external parasites, from un- 

 wise feeding and from garget of the udder. 



It is wise, therefore, to study carefully the 

 question of the internal parasite and to learn 

 ways of management that will avoid them. 

 This learned all the long catalogue of diseases 

 may repose serenely upon the library shelf, 

 since the occurrence of an instance of one of 

 them in the flock will be of the rarest. 



GAEGET OE MAMMITIS. 



This is a disease that affects the udders of 

 the very best and largest milking ewes, pre- 

 ferring those that are best bred and most cod- 

 dled. The symptoms are a hard, distended 

 udder, from which a changed sort of watery- 

 milk may be drawn, which often becomes 

 streaked with blood and sometimes with pus. 

 The flesh of the udder is often red or purple 

 and upon pressure can be dented with the hand. 

 The sheep has fever and distress, milk secretion 

 ceases, the udder mortifies and if the ewe lives 

 long enough it sloughs off, leaving a sore slow 

 to heal. In mild cases the symptoms are much 

 less severe and the ewe soon recovers, losing 

 perhaps the use of one quarter of her udder.
