Cattle are not so subject to worms proper as are the other domestic
animals; nor, when these parasites do exist, is any injurious effect
apparent, except it be in the case of young calves of a weakly
constitution. Worms are most commonly located in the small intestines,
and cause there considerable irritation, and consequently, general
emaciation, or at least a tendency to it.
The cause, however, is easily removed by administering doses of sulphate
of iron, one-half drachm each, in molasses once or twice a day.
