PROGRESSIVE SHEEP RAISING 



Diseases of Sheep 



All animals are subject to certain diseases and this fact 

 must be recognized by the owners of sheep. To deal with 

 disease successfully one must keep advised of the latest 

 remedies, and should, from time to time, write to his 

 Experiment Station for such information. 



Wing in Sheep Farming in America page 3 1 1 classifies 

 diseases among sheep as follows : 



"First, there may be some external 

 Sheep Diseases parasite, as the tick, louse, scab or foot- 

 Classified rot (which is in a sense an external 



disease) . 



"Second, there may be some form of internal para- 

 sitism. This may be worms in the stomach or intestines, 

 in the throat or lungs, or encysted worms making a bladder 

 in the brain. And one or another of these internal para- 

 sites is the cause of most of the sickness among sheep. 



"Last, there may be some derangement of the digestion 

 due to improper feeding, no feeding at all, or gorging 

 with grain. And in some regions, among the class of 

 sheepmen who feed sheep in winter, nearly all diseases are 

 of this origin. 



External "Now as to the chance of cure: For 



Diseases external parasites cure is easy and

 treatment and are no cause for alarm whatever except 

 as scab breaks out in the winter time in the middle of the 

 feeding season, when it is costly to dip and the sheep have

 to class these external parasites as diseases, any more 

 than fleas on a dog's back, though they produce disease if 

 left unchecked.
