DISEASES OF THE RESPIRATORY APPARATUS 97 



quently, there is more or less discharge from the nostrils and 

 the respirations may hecome labored when exercised. The ani- 

 mal is usually weak, in poor flesh and unfit for work. In other 

 cases, symptoms of broken wind are noticed. Severe coughing 

 spells on getting up from the bed, or on moving about are char- 

 acteristic of bronchitis in hogs. Verminous bronchitis in calves 

 and lambs is characterized by severe spells of coughing, difficult 

 and labored breathing and a weak, emaciated condition. 



The preventive treatment is the same as for " colds." In 

 the acute form the treatment consists largely in careful nursing. 

 Properly ventilated, clean quarters that are free from dust should 

 be provided. The animal should be covered with a light or 

 heavy blanket, depending on the temperature of the stable, and 

 the limbs bandaged. A light diet should be fed for a few days. 

 It is advisable to give the animal a physic of oil. The inhalation 

 of steam every few hours during the first few days should be 

 practised. Glycoheroin may be given three or four times a day. 



Animals affected with chronic bronchitis should not be 

 exercised or worked. We should guard against their taking 

 cold, give nourishing feeds, and a tonic if necessary. 



Congestion of the Lungs. — Pulmonary congestion is gener- 

 ally due to overexertion and exposure to extreme heat or cold. 

 It may occur if the animal is exercised when sick or exhausted. 

 Hogs that are heated from exercise and allowed access to cold 

 water, may suffer from a congestion or engorgement of the 

 lungs. It may be present at the beginning of an attack of 

 pneumonia or pleurisy. 



The symptoms are difficult breathing and the animal fights 

 for its breath. The body temperature may be several degrees 

 above the normal. In the mild form, the above symptoms are not 

 so marked; The onset and course of the disease are rapid, 

 recovery, pneumonia, or death often occurring within twenty- 

 four hours.
