THRUSH.
Veterinary writers are very fond of splitting hairs about words. Thrush, therefore, in most books, becomes "frush;" notwithstanding, if the reader should consult any professional authority, or a professor at either of the colleges, the person so appealed to will decidedly designate the disease as it is here spelled. The disorder therefore bears, in these pages, the name it carries in ordinary speech, and all far-fetched distinctions are discarded.
THRUSH IN THE FORE FOOT, WITH A THICK CRUST, A CONCAVE SOLE, AND A SMALL FROG.
Thrush is a foul discharge issuing from the cleft of the frog, and attended with disorganization of the horn. It is derived from two causes—either internal disease or bad stable management. When internal disease gives rise to thrush, it is present in the fore foot. The quarters of the hoof are strong and high; the sole is thick and concave; the frog small and ragged. When bad stable management provokes the disorder, it shows itself in the hind foot, which may be of any shape; but the frog is generally large, while the discharge is more copious than in the former instance.
It is sad to think that the creature which lives but to toil, and whose existence is a type of such slavery that its greatest freedom is to labor, should be begrudged the bed whereon it reposes, or be doomed to stand in filth which will generate disease. The horse's foot is not very susceptible to external influences. It is incased in a hard and inorganic, yet elastic substance. Thus protected, it appears like praising the ingenuity of man when we say such a body is not proof against his neglect. The hoof is made to travel through mud and through water; it is created to canter over sand and over stones. It is capable of all its purposes; but it only seems not fitted to be soaking days and nights in the filth of a human lazar-house. The drainage of the stable is too often clogged; the ventilation bad; the bedding rotten, and more than half composed of excrement. All that passes through the body, from the inclination of the flooring, tends toward the hind feet. Over this muck the animal breathes. In it the creature stands, and on it the victim reposes.
THRUSH IN THE HIND FOOT.
No wonder the horn rots when implanted in a mass of fermenting filth. The fleshy, secreting parts, which it is the office of the hoof to protect, ultimately become affected; they take on a peculiar form of irritation; from the cleft of the frog a discharge issues; it becomes colored and offensive through being mixed with the decaying horn; the smell is most abhorrent; frequently it taints the interior of the place, and to the educated nose thus makes known its presence.
The first thing is to clear the stable, then to cleanse it thoroughly. Bed down the stalls with new straw, and attend to the animals themselves. Wash the feet well with water, in every pint of which is dissolved two scruples of chloride of zinc. The fetor will thus be destroyed, and the animal be made approachable. Place some of the fluid, to be used as required, near the smith, while the man cuts away the diseased frog. All the ragged parts are to be excised. The knife is to be employed until all the white, powdery substance is effectually removed.
