Treatment. Dust fowls with fresh insect powder (pyrethrum). Smear sulphur ointment on head and under wings, especially in the case of chickens. Infested fowls may be dipped in 2% creolin. Dust setting hens with a lice powder before putting them on their nests. Infested straw should be burnt, and boxes, nests, fixtures, etc., should be thoroughly sprayed with 2% creolin.

LIMBER-NECK
An occasional complaint

Symptoms. The muscles of the fowl’s neck become so relaxed that they cannot support the head.

Cause. Limber-neck, due to partial or entire paralysis of the muscles of the neck, is believed to be associated with acute indigestion or worms.

Treatment. A strong purgative may be the means of effecting a cure by cleaning out any intestinal poisons and thus correcting the cause. If the treatment recommended does not effect a cure in a few days, kill the bird.

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:

1. Diseased livers due to indigestion, e. g., enlargement.

2. Diseased livers due to a specific disease, e. g., tuberculosis.
