Breed Description Appendix Horse: - A horse registered
with AQHA which is the result of breeding a Thoroughbred and an
American Quarter Horse that has a permanent number, or a combination
of an Appendix numbered American Quarter Horse and an American
Quarter Horse with a permanent number. Appendix horses are
distinguished by an "X" in front of their registration number and
their certificates are gold.
There are three
different mixes of horses that are eligible to be registered in
1. Registered Appendix (X) + Registered American Quarter Horse
(QH) ' Registered Appendix foal(X) 2. Registered American Quarter Horse (QH) + Registered American
Quarter Horse (QH) ' Registered American Quarter Horse foal (QH) 3. Recognized Thoroughbred (TB) + Registered American Quarter
Horse (QH) ' Registered Appendix foal (X)
Colors of Horses There are 13 recognized colors for
American Quarter Horses. Bay, Black, Brown, Sorrel, Chestnut, Dun,
Buckskin, Red Dun, Grullo, Palomino, Gray, Red Roan, Blue Roan.
Bay: Body color ranging from tan, through red, to reddish
brown; mane and tail black; usually black on lower legs. Black: Body color true black without light areas; mane and tail
black. Brown: Body color brown or black with light areas at muzzle,
eyes, flank, and inside upper legs; mane and tail black. Sorrel: Body color reddish or copper-red; mane and tail usually
same color as body, but may be flaxen. The most common color of
American Quarter Horses. Chestnut: Body color dark red or brownish-red; mane and tail
usually dark red or brownish-red but may be flaxen. Dun: Body color yellowish or gold; mane and tail may be black,
brown, red, yellow, white or mixed; often has dorsal stripe, zebra
stripes on legs, transverse over withers. Buckskin: Body color yellowish or gold; mane and tail black;
usually black on lower legs. Red Dun: A form of dun with body color yellowish or flesh
colored; mane, tail and dorsal stripe are red. Grullo: Body color smoky or mouse-colored (not a mixture of
black and white hairs, but each hair mouse-colored.) ; mane and tail
black; usually black on the lower legs; often has dorsal stripe. Palomino: Body color golden yellow, mane and tail white.
Palominos typically do not have dorsal stripes. Gray: Body color a mixture of white with any other colored
hairs; often born solid-colored or almost solid-colored and gets
lighter with age as more white hairs appear. Red Roan: More or less uniform mixture of white with red hairs
on the body, but usually darker on head and lower legs; can have
red, black, or flaxen mane and/or tail. Blue Roan: More or less a uniform mixture of white with black
hairs on the body, but usually darker on head and lower legs; can
have a few red hairs in mixture.
AAHA allows the horse breeder to take the Thoroughbred horse, the
Quarter Horse or Paint and make the Appendix breed. Breeding Stock
Paints are welcome to dual register without any prejudice to lack of
color, or the Paint with Thoroughbred in their bloodline may dual
register without prejudice to having color. The coded appendix horse
in the American Quarter Horse Association is welcome to register in
as the Appendix breed of horse. Allowing the owner to breed this
horse to other horses and keep the pedigree ongoing.
AAHA has an Enrollment program for horse owners of Quarter Horse,
Paints and Thoroughbred to enroll their horse's pedigree in AAHA, so
that the offspring of these horses are eligible for Registration
into AAHA as an Appendix breed. If you have a stallion this will
give you more revenue because you can offer mare owners breeding
certificate to register in AAHA. You may breed your Quarter Horse to
a Paint, Thoroughbred or another Appendix or coded appendix with
AQHA and offer the owner a way to register the foal. A Paint or
Thoroughbred stallion owner may also do the same thing.
History Since the American Quarter Horse formally
established itself as a breed, the AQHA stud book has remained open
to additional Thoroughbred blood via a performance standard. An
"Appendix" American Quarter Horse is a first generation cross
between a registered Thoroughbred and an American Quarter Horse or a
cross between a "numbered" American Quarter Horse and an "appendix"
American Quarter Horse. The resulting offspring is registered in the
"appendix" of the American Quarter Horse Association's studbook,
hence the nickname. Horses listed in the appendix may be entered in
competition, but offspring are not initially eligible for full AQHA
registration. If the Appendix horse meets certain conformational
criteria and is shown or raced successfully in sanctioned AQHA
events, the horse can earn its way from the appendix into the
permanent studbook, making its offspring eligible for AQHA
Since Quarter Horse/Thoroughbred crosses continue to enter the
official registry of the American Quarter Horse breed, this creates
a continual gene flow from the Thoroughbred breed into the American
Quarter Horse breed, which has altered many of the characteristics
that typified the breed in the early years of its formation. Some
breeders, who argue that the continued infusion of Thoroughbred
bloodlines is beginning to compromise the integrity of the breed
standard, favor the earlier style of horse, have created several
separate organizations to promote and register "Foundation" Quarter
Behavior Dependant on use.
Health Hyperkalemic periodic paralysis (HYPP), which
is caused by an autosomal dominant gene linked to the stallion
Impressive. It is characterized by uncontrollable muscle twitching
and substantial muscle weakness or paralysis among affected horses.
Because it is a dominant gene, only one parent has to have the gene
for it to be transmitted to offspring. There is a DNA test for HYPP,
the AQHA requires testing and is now limiting registration of some
horses who possess the gene.
Hereditary Equine Regional Dermal Asthenia (HERDA), also known as
hyperelastosis cutis (HC). This is caused by a recessive gene, and
thus, unlike HYPP, HERDA can only be transmitted if both parents
carry the gene. When a horse has this disease, there is a collagen
defect that results in the layers of skin not being held firmly
together. Thus, when the horse is ridden under saddle or suffers
trauma to the skin, the outer layer often splits or separates from
the deeper layer, or it can tear off completely. It rarely heals
without disfiguring scars. Sunburn can also be a concern. In
dramatic cases, the skin can split along the back and even roll down
the sides, with the horse literally being skinned alive. Most horses
with HERDA are euthanized for humane reasons between the age of two
and four years. The very hotly debated and controversial theory, put
forth by researchers at Cornell University and Mississippi State
University is that the sire line of the great foundation stallion
Poco Bueno is implicated as the origin of the disease. There
currently is no DNA test for HERDA, but active research is ongoing
to try and pinpoint the gene.
Function Racing, trail riding (endurance, pleasure,
mileage/hourly or working ranch), hunter/jumper, dressage, cutting,
ranch work or horse racing.
