Black Head and Roup 397 



BLACK HEAD 



This is a disease of turkeys and chickens, due to the 

 presence in the intestines of an animal germ. It is fre- 

 quently seen in the eastern states. 



There is diarrhea, resembling that of fowl cholera, 

 except that it is not so severe and is not attended with 

 great weakness and prostration. There is dullness or 

 partial stupor. As the disorder progresses, the comb, 

 and later the wattles, become dark purple, a symptom 

 from which the disease takes its name. 



At present there seems to be no satisfactory medic- 

 inal treatment. The best plan is to kill the bird as 

 soon as the first symptoms appear and burn the body. 

 The quarters should be disinfected and kept clean. The 

 food and water supply must be wholesome. If these 

 things are carefully looked after, and no diseased birds 

 are allowed to remain with the healthy ones, there is 

 little trouble in checking the difficulty. 



ROUP 



Roup is a contagious inflammation of the mucous 

 membranes of the head of fowls, associated with a 

 catarrhal discharge from the nostrils and eyes. It is a 

 common disease, especially when poultry is kept in 

 damp and unsanitary quarters. It is due to a germ 

 which may be introduced by means of diseased fowls, 

 or by infected coops or pens. Good care and food 

 enable birds to resist invasion by the germs. Any con- 

 ditions that tend to lessen the vitality of the bird favor 

 the development of the disease. ^
