18 LEHMAN'S POULTRY DOCTOR. 



Causes: The causes are similar to those of laryn- 

 gitis, such as exposure to cold, wet, diaughts, etc.; 

 or it may be caused by compelling fowls to inhale irri 

 tants; especially is dense smoke harmful. 



Symptoms: Breathing is rapid, there is a harsh, 

 whistling sound and cough in the first stages, followed 

 by loose rattling sounds made by the air passing 

 through the mucus in the tubes. 



The bird seems feverish and becomes weak, the 

 feathers are ruffled and in severe cases breathing be- 

 comes very difficult; the patient frequently opens its 

 beak in order to get sufficient fresh air. In such aggra- 

 vated form the fowl soon becomes exhausted and will 

 die if not quickly relieved. 



' Treatment: The cause must be sought and removed 

 and the general surroundings should be the same as 

 directed for laryngitis. Also give the fever medicine 

 (aconite and sweet spirits of niter) for a day or two 

 as directed on page 17. 



Give soft, light food, such as stale bread soaked in 

 milk, bran mash, boiled rice, etc. Follow the fever 

 medicine by giving 10 to 20 drops of the following, four 

 times a day: 



Muriate of Ammonia. . .10 gr. 



Syrup of Tolu 3^ oz. 



Fluid extract of licorice Yi oz. 



Steaming as directed for laryngitis is - also nec- 

 essary.
