hoof

(ho͝of, ho͞of)
n. pl. hooves (ho͝ovz, ho͞ovz) or hoofs
a. The horny sheath covering the toes or lower part of the foot of a mammal of the orders Perissodactyla and Artiodactyla, such as a horse, ox, or deer.
b. The foot of such an animal, especially a horse.

hoof

a horny casing of the toe produced by hardened epidermal cuticle (keratin), found particularly in UNGULATES.

hoof

the horny covering of the digit of ungulates. Consists of a wall, a sole and in the horse reflections of the wall which enclose a triangular frog. The hoof is attached to the underlying soft tissues by lamellae which interdigitate with similar lamellae in the soft tissues. The wall is composed of many minute horn tubes united by intertubular horn produced by a germinative layer at the coronary band where the skin and horn join. A thin, narrow band of soft, very light-colored horn called periople forms a flexible union between wall and skin. The wall is that part of the hoof extending from the coronet to the sole. It grows from the coronet and in horses takes about 1 year to reach the sole at the toe and some months fewer at the heel. The wall and the sole join at a visible band called the white line though this is often yellowish. These various parts of the hoof are described in more detail under their individual headings. See also cleat.

hoof abscess
results usually from a nailprick of the sole or from a cracked sole. The cavity of the abscess cannot be large because of the rigid nature of the tissues. Spread from the original site is via the potential space between the sensitive laminae and the hoof and eventually surfaces at the coronet with pus discharging from a sinus there. Causes severe lameness, and tetanus is a common accompaniment.

hoof overgrowth
in old animals kept on very soft pasture or bedding; the hoof wall elongates and will eventually curl under so that the patient is walking on hoof wall instead of sole.
hoof pick
a pointed appliance in various shapes used to pick dirt and stones out of the grooves in the sole of a horse's hoof.
hoof slough
the wall and sole are detached from the sensitive laminae and the coronet and falls off. When the detachment is partial, the hoof is retained but is not viable and the patient gives the appearance of wearing slippers.
hoof tester
shaped like a pair of large pincers. One of the blades is placed on apparently normal hoof and the other on the part to be tested. If there is a flinch response when the handles are squeezed this is taken as an indication of pain at one of the pressure sites.
hoof ulcer
see pododermatitis circumscripta.
worn hoof
excessive wear, e.g. that which occurs in pastured cows forced to walk twice daily along races floored with recently paved non-slip concrete; may expose sensitive tissue, causing herd level lameness in all four limbs.
