Cause.—Small portions of tapeworms, consisting of one or more segments, are occasionally seen in the droppings of infected cattle. The infection is undoubtedly taken in with the food or water, infection being spread by the eggs of the parasite, and being expelled with the feces of an infected animal. The eggs being swallowed by insects, worms or snails, which act as an intermediate host, and which when swallowed accidentally by cattle while grazing or drinking carry with them into the animal’s stomach the infectious stage of the tapeworm. Aged cattle do not seem to suffer much from tapeworms, but in calves these parasites cause scours and rapid emaciation.

Symptoms.—Emaciation, diarrhoea, loss of flesh, ravenous appetite, paleness of the mucous membranes of the mouth and eyes, and the segments of the tapeworms can occasionally be seen in the droppings.

Treatment.—Withhold all food from eighteen to twenty-four hours, and to calves from two to eight months old give two teaspoonfuls of gasolene in a pint of milk. To yearlings, place one tablespoonful in a gelatin capsule and give with capsule gun. To cattle one year and over, place one ounce in capsule and give with capsule gun. Repeat this treatment two or three times during intervals of a week or two.
