Is a very common disease among horses. It is generally the result of irregular and injudicious feeding. It comes on slowly, and therefore is not noticed until it has a fast hold upon the animal.
Symptoms. - The horse has a rough, staring coat and a dull appearance generally; the appetite varies; sometimes he eats fairly well, but at other times the food remains untouched; he eats very little hay at any time. The bowels are sometimes loose and at others constipated; the manure is of a pale or clay color and the animal often has slight attacks of colic. If you put your hand back in his mouth the saliva from the tongue has a foul odor.
Treatment. - Give five to eight drachms of Barbadoes aloes combined with one drachm of calomel. In twenty-four hours begin with the following, giving a tablespoonful three times a day: Powdered charcoal, bicarbonate of soda and gentian root, equal parts, mixed. The feed should be bran and oats and good hay. A little salt should be given once every day, and the animal should be watered half an hour before each meal but not soon after the meal.
