CHOLERA

Fowl typhoid, or leukemia, is a disease of the blood that may be mistaken for cholera. The poultryman must treat it in the same way.

CLOACITIS OR VENT-GLEET

COCCIDIOSIS OF ADULT FOWLS

COLD

CONSTIPATION

CRAMP

NOTE--In cases of rheumatism, tick fever, and tuberculosis, birds may show the same difficulty in standing that they do in cramp.

CROP-BOUND

DIARRHEA OR ENTERITIS

Diarrhea is a common complaint among fowls, and in some cases takes a severe and epidemic form. The latter form may be due to various causes, and it will be best, perhaps, to deal with diarrhea under the following heads:

DIPHTHERIA OR DIPHTHERITIC ROUP

The term canker is also applied to certain spots or growths that occur on the throat. These are not in any way associated with diphtheritic roup, or any dangerous, contagious disease, and are due to injury or to an unhealthy condition of the mucous membrane.

DROPSY

DYSENTERY

EGG-BOUND

EGG-EATING

EMPHYSEMA

EPILEPSY

FATTY DEGENERATION

FAVUS

FEATHER-EATING

FLEAS

FRACTURES

Broken bones of legs or wings can be mended by placing the bones back in their proper positions and binding with light splints. The splints may be removed in about four weeks. It will be found that shanks are easily set, but that broken wings give far more trouble.

If a fowl dislocates its leg or its wing, the joint should be gently pushed back into place.

FROST BITE

GAPES

GASTRITIS

GOUT

HEART DISEASES

The heart is an organ that is subject to several serious diseases, but these cannot be detected with any certainty while the bird is living, and treatment cannot be recommended as likely to be successful. Post-mortem examination may show the following symptoms:

INDIGESTION

JAUNDICE

KIDNEY DISEASES

Gout is the commonest disease of the kidneys. In addition, there are some disorders of the kidneys that may be noticed on post-mortem examination. Little is known about these diseases; there are no symptoms that can be recognized before death, and no treatment can be recommended.

LEG WEAKNESS

LICE

Several species are found on fowls. Fig. 14 shows three of the common species.

LIMBER-NECK

LIVER DISEASES

The liver is affected by several diseases, and the poultryman, who finds a spotted liver on post-mortem examination, will be much aided in determining the cause, if he takes into consideration the symptoms noticed before the fowl died, as well as the changes in the other internal organs. The importance of the post-mortem examination is in distinguishing whether the death of the fowl is due to a contagious disease.

The causes of diseased livers may be conveniently divided into two classes:

In this class may be included degeneration, inflammation, congestion, enlargement, and atrophy of the liver. There are more or less distinct differences in these diseases, but the only possible methods of treatment known at present are very much the same.

Tuberculosis, coccidiosis, gout and other specific diseases are responsible for spotted or diseased livers. The section on diagnosis by post-mortem examination gives further information on these subjects and shows how the principal diseases may be distinguished.
