All of these are substantially different stages and symptoms of the same disorder. Exposure to wet and cold is the general cause. Cough is, indeed, a symptom, not a disease, and is connected with the other three. It may, however, attend other diseases, and when its cause is not known, the article pertaining to roup should especially be consulted. Bronchitis is but an advanced stage or aggravated form of cold or catarrh. The three are marked by more or less discharge from the eyes and nostrils, sneezing, wheezing, and, particularly in bronchitis, coughing and a rattling sound in the throat. To distinguish this from roup, see whether the discharge is offensive. If it is, roup is to be treated; if not, catarrh or bronchitis. In all cases of doubt, use the precautions detailed for roup. Turkeys are subject to roup from the time they are babies, more so than common hens, as a cold is the cause of all their trouble. Treatment: Remove the turkey to warm, dry shelter, and give warm, soft food. These measures will usually be sufficient, but the following will be valuable as aids: _For cold or catarrh_ merely, and no distinction between them is here made, put three drops of strong tincture of aconite in a pint of the drink. If there is a swelling about the throat, two or three grains of the second trituration of mercuries three times a day will be useful. _For bronchitis_, in addition to the measures just named, give sweetened water for the drink, adding a few drops of nitric acid or sulphuric acid. _For both catarrh and bronchitis_ give some stimulant, such as ginger or cayenne pepper in the food or whisky in the water. Treat catarrh and cold promptly, to keep them from developing into roup. Do not neglect bronchitis lest it run into consumption. ROUP Roup is a highly contagious malady which first affects the lining membrane of the beak and then extends to the eyes, throat, and whole head, eventually involving the entire constitution. According to its manifest symptoms, it has been called diphtheria, sore head, swelled eyes, hoarseness, bronchitis, canker, snuffles, influenza, sore throat, quinsy, blindness, and by other names. It attacks all ages, and will kill young turkeys in a very short time. Turkeys given poor shelter, and kept in filthy quarters, are subject to roup.
