162 PRACTICAL POULTRY PRODUCTION 



ing the nostrils with either of the following solutions by 

 means of a medicine dropper (Figure 161) or by immersing 

 the head of the bird in a basin containing the mixture and 

 holding it there for a few seconds, care being taken not to 

 hold the bird long enough to cause suffocation. Suitable 

 remedies for such treatment are boric acid 1 oz., water 1 

 quart, or potassium permanganate 1 dram, water 1 pint; 

 or boric acid IM oz., borax 3^ oz., and 1 quart water. Hydro- 

 gen peroxide used in the proportion of 1 oz. to 3 ozs. of 

 water is sometimes effective. As a general treatment and 

 preventive, dissolve in one gallon of drinking water as much 

 potassium permanganate as will remain on the surface of 

 a dime. The flock should be given no other drinking water 

 than that containing the potassium permanganate. It is 

 good practice to use potassium permanganate in the drink- 

 ing water as a preventive as soon as cool weather begins 

 in the fall.

 also known as diphtheretic roup. 



Symptoms. This disease is characterized by cheese- 

 like patches that form on the membrane of the mouth, 

 throat, and tongue. 



Treatment. Sprinkle a little sulphur or chlorate of 

 potash in the mouth and throat of the bird. Another 

 effective treatment consists of washing the sore patches with 

 a mixture of equal parts of hydrogen peroxide and water. 



Cholera. This is probably one of the worst diseases 

 that affects poultry, for it spreads rapidly and in most 

 instances the cure is unsatisfactory. Fortunately, however, 

 this disease is very rare and is frequently mistaken for other 

 troubles that are less serious. 



Symptoms. The usual symptoms of cholera are as 

 follows: The fowl is troubled with diarrhea, the droppings 

 become watery and yellow or green in color, the fowl is
