368 THE STOCK owner's ADVISEE. 



Symptoms. — Tlie disease begins with a cliillj soon followed by 

 febrile symptoms. There will be a hnsky, dry cough, and the 

 animal will retain the standing postnre. The pulse is quickened, 

 rhonchus is heard by auscultation, and the bowels are constipated. 

 Soon there is a discharge from the nose; if yellow, it is a favor- 

 able symptom. 



Treatment. — The animal shoukl be made to inhale medicated 

 steam, which may be medicated with camphor, creosote, or car- 

 bolic acid. The steam facilitates the passage of the fluid from the 

 bronchi. The sides may be stimulated with mustard and water, 

 or stimulating liniments. Where the cough is very distressing, 

 camphor, belladonna, and digitalis, a drachm of each, should be 

 given three times a day. In the primary stages of the disease, a 

 strong opiate may be given, as opium tincture, two ounces. If 

 the bowels are constipated, a pint of linseed oil should be given. 



Bronchitis may terminate in thick wind. 



PULMONARY EMPHYSEMA. 



Asthma, Broken Wind, or Heaves. — This is a dietetic dis- 

 ease of a non-inflammatory nature, characterized by difficult 

 respiration, and the presence of a prolonged and deep cough. 



Cause. — It is caused by injudicious feeding, allowing the ani- 

 mal to overload his stomach, feeding on dusty hay, or bulky or 

 dusty food of any kind. Cold and exposure exercise some influ- 

 ence in producing the disease, and it may result from an attack of 

 bronchitis. 



Symptoims. — There will be noticed a heaving of the flanks, 

 which will be greatly increased when the animal is put to severe 

 exertion. This is a peculiar bellows-like movement of the flanks. 

 The inspiratory act is performed regularly and easily, while the 

 expiratory act is difficult, and accomplished in a violent manner. 

 Another well-marked symptom, and all that is necessary to diag- 

 nose this condition, is a loud, deep, prolonged, and sonorous 

 cough. This cough is peculiar to broken wind, and will be readily 

 recognized, if ever once heardo^
