DISEASES. 



Roup is a name given to diseases of the mouth, 

 nose, and throat where the membranes hecome in- 

 flamed and the secretions somewhat thickened. There 

 is however, two different kinds of Roup namely: Wet 

 Roup and Dry Roup. Wet Roup is probably the 

 most common of the two and the most serious m na- 

 ture. 



Cause: It is probably in the beginning caused by 

 poor ventilation of the loft which is at the same time 

 overcrowded, whereby the birds are compelled to in- 

 hale vitiated air. This disease seldom appears in lofts 

 well taken care of and when kept in a good sanitary 

 condition at all times. Another probable cause of 

 Roup is from a deficiency of salts in the food, and al- 

 so the feeding of too much -carbonaceous and not suffi- 

 cient nitrogenous food thereby not providing enough 

 proper nutriment to the tissues of the body to supply 

 the want taken up by the amount consumed. Some 

 claim Roup is caused by a chill or the effect of a very 

 severe cold taken during damp weather but the author 

 thinks this is not the direct cause it only making the 

 membranes still more sensitive to the disease (which 

 has already taken hold to a certain extent upon the 

 bird) as tubercles have already formed for some time 

 prior to any symptons noticeable, the bird having prob- 

 ably taken cold after the high fever, which always ac- 

 companies this disease, had somewhat lowered which 

 leaving the pores more or less open, and the cold or 

 congestion following. This disease is exceedingly con- 

 tagious especially when it appears in the severest form, 

 all the birds in the same loft being liable to contract
