Cause.—May be due to a morbid condition of the brain or spinal cord, concussion of the spinal cord, fractures of the bones of the spinal column, or violent shocks or jars of the brain, or pressure due to fractures of the skull, or dilated or ruptured blood vessels. Paralysis also occurs in poorly fed, weak cows when exposed to cold or wet weather during the latter stages of pregnancy. Sometimes the back portion of the bowels (the rectum) becomes paralyzed so as to interfere with the expulsion of the feces which becomes dry and more or less impacted. This condition may also occur in connection with Ergot, Forage or Lead Poisoning, Milk Fever or Parturient Apoplexy.

Symptoms.—Appear very suddenly. The animal is unable to stand, lies quietly and groans occasionally. Constipation generally accompanies this condition. Sometimes great pain is present, especially if due to fracture or pressure, as above mentioned.

Treatment.—If just due to weakness; exposure to cold, wet weather; cows prior to calving; slight injuries or mild effect of poisons, it is successfully treated by placing the animal in a comfortable, well lighted stall, omitting drafts, feeding nourishing food, as warm wheat bran mashes, steamed rolled oats or barley and linseed meal; tea to drink prepared as follows: Pour one quart of boiling water on one-half pint of Pure Flaxseed, allowing it to cool, compel the animal to drink it. Repeat this once or twice daily, especially if the animal is pregnant. A physic consisting of Aloin, two drams; Ginger, two drams; prepared in capsule and given with a capsule gun is very effective, but this, however, should not be administered to heavily pregnant cows. Endeavor to move their bowels by careful feeding of laxative food and rectal injections of soda and water. Nerve stimulants are necessary and I have derived good results from the following: Pulv. Nux Vomica, four ounces; Pulv. Ginger, four ounce; Pulv. Gentian Root, four ounces. Make into sixteen capsules and give one capsule every four to six hours. Also apply powdered mustard, moistened with a sufficient quantity of water to make a paste, and rub over the full length of the spine about eight inches in width. This should be covered with paper which will adhere readily to the mustard and water. This application can be repeated every twenty-four hours until satisfactory results have been obtained.
