permitted to start unless the field is reduced by
scratches below a specified number.
- angular limb deformity
- A limb that is not conformationaly correct because
of developmental problems in the angles of the joints.
- anhydrosis
- Inability to sweat in response to work output or increases
in body temperature. Also known as a "non-sweater." Most are
athletic horses though frequently the condition appears in
pasteured horses not being ridden. Most commonly occurs when
both the temperature and humidity are high. Horses raised in
temperate regions and then transported to hot climates are most
prone to develop the condition but even acclimated horses can be
at risk. Clinical signs include inability to sweat, increased
respiratory rate, elevated body temperature and decreased exercise
tolerance. The condition can be reversed if the horse is moved to a
more temperate climate.

rider: usually 10 pounds until the fifth winner, seven pounds
until the 35th winner and five pounds for one calendar year from
the 35th winner. More rarely, a three-pound allowance is allowed
to a rider under contract to a specific stable/owner for two
years from his/her first win. This rule varies from state to
state. Apprentices do not receive an allowance when riding in a
stakes race. All jockeys going from track to track must have a
receipt from the clerk of scales from their track verifying the jockeys'
most recent total number of wins. Also known as a "bug," from the
asterisk used to denote the weight allowance.
- apron

- arthritis
- Inflammation of a joint. An increase in the amount of synovial

synovial fluid in the fetlock joint is called a "wind puff" or "wind gall."
In young horses, a swelling in the fetlock joint, particularly on the
front of the joint where the cannon and long pastern bones meet, is
called a "green osselet." This swelling is a result of inflammation and
reactive changes of the front edges of these two bones and adjacent
cartilage. If the green osselet does not heal, a "chronic osselet" might
develop with a permanent build-up of synovial fluid in the joint and
inflammation and thickening of the joint capsule over the damaged area with
secondary bone changes following the initial inflammation.

- bit
- A stainless steel, rubber or aluminum bar, attached to the bridle,
which fits in the horse's mouth and is one of the means by which a
jockey exerts guidance and control. The most common racing bit is the
D-bit, named because the rings extending from the bar are shaped like the
letter "D." Most racing bits are "snaffled," (snaffle bit) which means the
metal bar is made up of two pieces, connected in the middle, which leaves
it free to swivel. Other bits may be used to correct specific problems,
such as bearing in or out.
- black
- A horse color which is black, including the muzzle, flanks, mane,
tail and legs unless white markings are present.
- black type
- Boldface type, used in sales catalogues, to distinguish horses that
have won or placed in a stakes race.
Many sales catalogues have eliminated the use of black type for
stakes below a certain monetary level-$15,000 in 1985, $20,000
from 1986-1989 and $25,000 beginning in 1990. If a horse's name
appears in boldface type in a catalogue and in all capital
letters, it has won at least one black-type event. If it appears
in boldface type and capital and lower case letters, it was
second or third in at least one black-type event. Black type was awarded to
fourth-place finishers in races before Jan. 1, 1990.

the lungs' air sacs (alveoli) rupture. The medical term is "exercise-induced
pulmonary hemorrhage" (EIPH). Blood may be seen coming out of the horse's
nostrils, known as "epistaxis," although it is typically discovered by a
fiber optic endoscopic examination after exercise. Hot, humid weather and
cold are known to exacerbate the problem. The most common preventative
treatment currently available is the use of the diuretic furosemide (Lasix).
Less than one bleeder in 20 shows signs of epistaxis. See "Exercise-Induced
Pulmonary Hemorrhage" subsection of "Respiratory System" in veterinary
supplement for a more detailed explanation.

swelling. The most common site of injury is in the superficial flexor
tendon between the knee and the ankle. Despite aggressive treatment with
anti-inflammatory drugs, physical therapy and rest, horses commonly
reinjure the tendon when they go back into competition. Two surgeries are
felt to aid horses to come back to racing: tendon splitting at the lesion
site to release accumulated fluid and blood, and superior check ligament
desmotomy. The latter surgery is designed to reduce forces on the tendon
when the horse returns to training and racing.

This is sometimes known as "choking down," but the tongue does not actually block the airway. The base of the tongue is connected to the larynx, of which the epiglottis is a part. When the epiglottis is retracted, the soft palate can move up into the airway (dorsal displacement.) This condition can sometimes be managed with equipment such as a figure eight noseband or a tongue tie. In more extreme cases, surgery might be required, most commonly a "myectomy."
- Dosage
- Although there are actually many "Dosage theories," the one most commonly thought of as Dosage is the one as interpreted by Dr. Steven Roman. A variation of Dr. Franco Varola's work on pedigree analysis, the system identifies patterns of ability in horses based on a list of prepotent sires, each of whom is a chef-de-race. The Dosage system puts these sires into one of five categories brilliant, intermediate, classic, solid and professional, which quantify speed and stamina. Sires can be listed in up to two chef-de-race categories. Each generation of sires is worth 16 points, divided up by the amount of sires, i.e., the immediate sire is worth 16 points while the four sires four generations back are worth four points apiece.
- Dosage index (DI)
