ROUND WORM.
Cause.—An animal swallowing the eggs of the parasite in food or water which has been contaminated with the feces of infected cattle. There are two species, the large Roundworm measuring from five to fourteen inches in length, the small Roundworm varying in size from one-quarter of an inch to two inches in length. Both the small and large Roundworms infest the intestines of cattle and calves. These worms, especially small Roundworms, irritate the mucous lining of the intestines, which may cause severe inflammation.
Symptoms.—Anemia, appetite variable, diarrhoea, general weakness, dullness and excessive thirst; also a paleness of the visible membranes of the mouth, nose and eye. Worms frequently pass with the feces and can be readily seen by a close observer.
Preventive Treatment.—See prevention of Twisted Stomach Worm.
Medical Treatment.—Withhold all food from eighteen to twenty-four hours. To calves, two to eight months old, give two teaspoonfuls of Turpentine in a pint of milk; to yearlings, give one tablespoonful. Place in gelatin capsule and give with capsule gun. To cattle one year old and over place one ounce in a gelatin capsule and give with capsule gun. This treatment is to be repeated twice during the intervals of ten days or two weeks, which insures the expulsion of the eggs of worms that escaped the first treatment. Also keep salt where cattle can lick frequently.
