Over time, horses with DSLD develop suspensory ligaments that do not properly support the fetlock joint. Without proper support from the suspensory ligament the fetlocks drop and the pasterns flatten out until they are nearly parallel to the ground.
Every purebred Arabian horse registered with the Arabian Horse Association is assigned a unique registration number. These numbers are always prefixed by the studbook abbreviation "AHR*".
The letters AA after a racehorse's name stand for Anglo-Arabian - a separate breed to thoroughbreds which is the result of various crosses between thoroughbreds, Arabian and Anglo-Arabian horses. To qualify as Anglo-Arabian or AA, at least 12.5 per cent of a horse's genetic make-up must be Arabian.
Cerebellar Abiotrophy (CA) is a neurodegenerative disease in Arabian horses affecting the cerebellum, more specifically the Purkinje neurons. Although CA occurs in several domestic species, CA in Arabian horses is unique in that a single nucleotide polymorphism (SNP) has been associated with the disease.
DSLD horses will be severely lame on affected limbs after a fetlock flexion test and will be noticeably painful on palpation of the suspensory ligament and its branches. The suspensory will also feel harder and thicker than normal, and the area may be hot or swollen.
Treatment success with traditional options—including rest, support bandages, and anti-inflammatory medication—has been limited. Veterinarians have also started using stem cell or protein-rich plasma (PRP) injection directly into affected ligaments in an attempt to improve healing.
Weak Pasterns, also referred to as "Low in Pasterns", is when muscles/ligaments etc are growing faster than the bones and they have nothing to attach to for support. Nutrition is the leading cause of weak pasterns, buckling over and splayed feet.
Description of the Sport. The Standardbred (STB) was developed as a racing breed by registering any horse that could trot or pace 1 mile in a set time, called the standard.
BD. Indicates the horse was brought down by another runner. BF. Stands for the beaten favourite and indicates a horse was favourite for a race but did not win.
Refused To Race – R or RR. A horse gets to the starting line and simply refuses to start the race.
Degenerative Suspensory Ligament Desmitis (DSLD) is a chronic condition in horses that affects connective tissue, including the suspensory ligament and other ligaments and tendons. This painful condition commonly leads to debilitating lameness.
Standardbred Trotter
A champion trotter, known as Lee Axworthy, was the first horse in racing history to trot a mile (1.6 kilometers) in less than two minutes. His skeleton shows the long, low lines of a typical American standardbred, the fastest of all trotting breeds.
Knuckling refers to flexion of the fetlock joint caused by damage to spinal cord, nerves, muscle or tendons. There may be partial flexion where the soles of the hooves are bearing weight, or extreme flexion where the front of the pastern is bearing weight. Many injuries or conditions may cause knuckling.
Weak flexor tendon in horses is also known as flaccidity or dropped fetlocks. Typical symptoms include not weight bearing on the toe like he should, hyperextension of the leg, and improper hoof placement. The tendon and the muscle in the area lack strength and cause the foal to use his leg improperly.
The most commonly implicated tendon associated with subtle dropping of the fetlock is the suspensory ligament. Cutting of the flexor tendons and suspensory ligament causes collapse of the fetlock to the ground. There is a great range of normal conformation in horses.
In equestrian, the head, shoulder and arm are most vulnerable body parts to injury. Most injuries occur as a result of falling off the horse. The rider may sometimes fall on their shoulder or head. The severity of the injury depends on the surface the rider falls onto, how they land and how fast the horse is going.
Fetlock lameness is usually a result of arthritis, fractures or injuries of the suspensory apparatus. This structure is susceptible to damage because of the high concussive forces on the fetlock joint when moving. Improper hoof angles or genetically long pasterns can also predispose horses to fetlock lameness.
Signs of lameness become more apparent and won't resolve through treatment. You may also notice that the SL feels thicker and harder than it should, and the area feels hot and swollen. The horse's gait may become unstable and appear as if it has a neurological condition due to the weakened nature of its SL.
Black is one of the least common coat colors in Arabian horses, as it's often suppressed by the dominant Agouti gene. The Agouti gene (A) is responsible for bay coat coloring and is visible only on black.
Summary. Serum amyloid A (SAA) is the major acute phase protein in horses. It is produced during the acute phase response (APR), a nonspecific systemic reaction to any type of tissue injury. In the blood of healthy horses, SAA concentration is very low, but it increases dramatically with inflammation.
Roaring (laryngeal hemiplegia) is a condition in horses that greatly reduces their airflow during exercise. Affected horses make a “roar” sound under work. Damage or breakdown of the laryngeal nerve causes roaring. The term laryngeal hemiplegia means paralysis of half of the larynx.
