MOUNTED INSTRUCTION 65 



In order to prevent the intrdduction of tlic disease it is advisable 

 to isolate animals that are issued to organizations for at least one 

 week. Furthermore, the stabling of healthy horses in feed stables 

 should be guarded against. At the beginning of an outbreak the 

 disease may be checked by immediate isolation of the infected horses, 

 and later by the segregation of those showing a marked increase in 

 temperature. Contagious pneumonia is an acute inflammation of 

 the lungs. The same procedure as gi\-en for influenza should be car- 

 ried out in the prevention of this infection. 



GLANDERS AND FARCY 



Let it be understood at the outset that the glanders and farcy are 

 one and the same disease, differing only in that the first is usually ap- 

 plied to the disease when the local lesions predominate in the internal 

 organs, especially in the nostrils, lungs, and air tubes, and that the 

 second term is applied to it when the principal manifestation is an 

 outbreak of the lesions on the exterior or skin of the animal. The 

 term glanders is sometimes applied to the disease in both forms, while 

 the term farcy is limited to the visible appearance of the external 

 troubles only ; but in the latter case internal lesions always exist, 

 although they may not be evident. It is characterized by the forma- 

 tion of nodules of connective tissue which degenerate into ulcers, 

 from which exudes a neculiar discharge. 



THICK WIND AND ROARING 



Horses afifected with a clironic disease that causes a loud unnatural 

 noise in breathing are said to have thick wind, or to be roarers. Their 

 class does not include those afifected with severe sore throat, as in 

 these cases the breathing is noisy only during the attack of the acute 

 disease. Thick wind is caused by an obstruclion to the free passage 

 of the air in some part of the respiratory tract. 



The conifort and surrounding of the patient must be attended to 

 first. The quarters should be the best that can be provided. Pure 

 air is essential. Avoid placing the animal in a stall where he may 

 be exposed to drafts of cold air and sudden changes of temnerature. 

 It is much better for the animal if the air is cold and pure than if it 

 is warm and foul. It is better to make the animal comfortable with 

 warm clothing than to make the stable warm by siuitting off the 

 ventilation. From the start the animal should have an imlimited 

 supply of fresh, cold drinking water. Blanket the body. 



HEAVES, BROKEN WIND 



Heaves is usually associated uith digestive disorders or an error 

 in the choice of feed. Feeding on clover hay or damaged hay or straw. 

 too bulky and innutritions feed, and keeping the horse in a dusty
