PARASITES AND DISEASES OF POULTRY 



symptoms of disease remove at once to some iso- 

 lated place, feed very lightly on mostly green food, 

 administer a remedy, and be guided further by 

 the persistency of the attack. Medicines and drugs 

 prepared for human beings can often be used to 

 advantage for fowls, as the effect is much the same, 

 but the dose should, of course, be lessened for 

 fowls. 



Roup is one of the most contagious and destruc- 

 tive diseases among fowls, and is especially preva- 

 lent in the fall and winter months. It 

 is a contagious catarrhal disease, char- 

 acterized by running at the eyes and nostrils, puffed 

 eyes, and swollen head; later, mouth and throat 

 become filled with foul-smelling mucous, or some- 

 times cheesy matter. The disease is caused by its 

 own special germ, but the predisposing causes are 

 usually dampness or drafts, while crowding, filth, 

 and almost any neglect or mismanagement may 

 also be a factor. Colds and catarrhal disorders 

 often develop into roup if neglected. Diphtheria 

 or diphtheritic roup is similar to ordinary roup, 

 but perhaps a little worse. 



Roup is a very difficult disease to cure, and per- 

 haps the easiest and most reliable way is to use one 

 of the advertised roup cures. With this disease, in 

 addition to isolating all afflicted birds, establish a 

 .quarantine for all suspects. If a patent roup cure 

 is administered, use peroxide of hydrogen once a
