 DISEASES OF THE RESPIRATORY SYSTEM. 



PNEUMONIA. 



This sometimes occurs in hogs, and the causes are similar to 

 those producing the disease in other animals, as sudden altera- 

 tions in temperature, exposure, etc. It is produced sometimes 

 by using a close pen, with an adjoining unprotected inclosure 

 for the animals to run in. The change from the close pen into 

 the open air, with no protection from the wind_, results in colds 

 and pneumonia. An animal taken from a wann pen and turned 

 on pasture, with no protection at night, will sometimes suffer 

 with colds and lung troubles. 



Symptoms. — The animal stands or sits up most of the time; 

 there is an elevation in temperature; the pulse is increased, with 

 increased respirations; there is a frequent cough; the limbs be- 

 come cold; the animal stands with the back arched and the nose 

 low to the ground. Auscultation and percussion are of little aid 

 in the diagnosis of lung disease in the hog. 



Treatment. — Tincture of aconite, in from five to ten drop 

 doses, should be used. If the animal shows great weakness, with 

 a weak pulse, a drachm of alcohol should be given three times a 

 day. Xitrate of potash, dissolved in the drinking water, is bene- 

 ficial. If the animal will not take it in the drinking water, 

 drachm doses should l)e given along with the drench. Milk 

 should be given as soon as the appetite returns, and finally 

 stronger food may be given. Mustard should be applied to the 

 lungs. 



The hog may have bronchitis, laryngitis, trachitis, etc. The 

 causes, symptoms, and treatment are similar to those of the same 

 diseases in other animals. The dose for the hog is about one- 

 eighth that of the horse.
