160 PROGRESSIVE POULTRY CULTURE 



roup should never be used thereafter for breeding stock. 



Tuberculosis In cases of tuberculosis there is devel- 

 opment of internal tubercles varying in size from ex- 

 treme minuteness up to the size of a walnut. These 

 tubercles frequently form in the lungs but may develop 

 in other parts of the body, particularly the spleen and 

 liver. If the lungs are affected there may be rapid, 

 troubled breathing, accompanied by some fever and 

 sometimes wasting of the flesh. Diarrhea may attend 

 the disease, increasing as the disease advances. The 

 bones and their joints are sometimes involved and swel- 

 lings form, causing lameness. Occasionally ulcerous 

 growths appear on the surface of the body. Exhaustion 

 finally results in death. 



If tuberculosis enters a flock of fowls the only safe 

 way to follow is destruction and burning of all the 

 birds of the flock. The quarters should then be thor- 

 oughly cleaned and disinfected by spraying with five 

 per cent, solution of carbolic acid.* Even the soil of the 

 runs should be disinfected. Expose the quarters to sun- 

 shine and winds for at least a month, or better, for a 

 year before again attempting to keep poultry on the 

 premises. A better plan is to choose another location 

 for the poultry plant. 



Vertigo A rush of blood to the brain accompanied 

 possibly by a slight hemorrhage may cause giddiness, 

 staggering gait, walking in a circle, slight convulsions 

 and throwing of the head up and back while the bird 

 squats upon the ground. Old fowls, especially if "exces- 

 sively fat, are. liable to attacks of vertigo. 



The fowls may be killed and dressed for the table. 



If it is desired to try to save a fowl affected with 

 vertigo, correct the feeding by balancing the rations 

 and including abundant green food, encourage active 

 bodily exercise by scattering the small grains far and 

 wide over the grass range or throw into straw litter in 

 the house or yard. Relieve the head by applications of 

 chopped ice or cloths wet witn cold water. Give Spsom 

 salts thirty grains and bromide of potassium three 

 grains In a tablespoonful of water, three times daily.
