The American Quarter Horse, or Quarter Horse, is an American breed of horse that excels at sprinting short distances. Its name is derived from its ability to outrun other horse breeds in races of a quarter mile or less; some have been clocked at speeds up to 44 mph (70.8 km/h). The development of the Quarter Horse traces to the 1600s.
Equestrianism, commonly known as horse riding or horseback riding, includes the disciplines of riding, driving, and vaulting. This broad description includes the use of horses for practical working purposes, transportation, recreational activities, artistic or cultural exercises, and competitive sport.
Laminitis is a disease that affects the feet of ungulates and is found mostly in horses and cattle. Clinical signs include foot tenderness progressing to inability to walk, increased digital pulses, and increased temperature in the hooves. Severe cases with outwardly visible clinical signs are known by the colloquial term founder, and progression of the disease will lead to perforation of the coffin bone through the sole of the hoof or being unable to stand up, requiring euthanasia.
A snaffle bit is the most common type of bit used while riding horses. It consists of a bit mouthpiece with a ring on each side and acts with direct pressure. A bridle utilizing only a snaffle bit is often called a "snaffle bridle", particularly in the English riding disciplines. A bridle that carries two bits, a curb bit and a snaffle, or "bradoon", is called a double bridle.
Robert Cook is an equine veterinarian. He has published many papers, mainly on diseases of the horse's mouth, ear, nose and throat both in scientific and horseman's journals, covering various topics:
Equine anatomy encompasses the gross and microscopic anatomy of horses, ponies and other equids, including donkeys, mules and zebras. While all anatomical features of equids are described in the same terms as for other animals by the International Committee on Veterinary Gross Anatomical Nomenclature in the book Nomina Anatomica Veterinaria, there are many horse-specific colloquial terms used by equestrians.
Rollkur or hyperflexion of the horse's neck is defined as "flexion of the horse's neck achieved through aggressive force" and is banned in International and Olympic sanctioned equestrian sports by the governing body, the International Federation for Equestrian Sports (FEI). The FEI recognises a distinction between rollkur and the riding of the horse in a deep outline not achieved by force.
Exercise-induced pulmonary hemorrhage (EIPH), also known as "bleeding" or a "bleeding attack", refers to the presence of blood in the airways of the lung in association with exercise. EIPH is common in horses undertaking intense exercise, but it has also been reported in human athletes, racing camels and racing greyhounds. Horses that experience EIPH may also be referred to as "bleeders" or as having "broken a blood vessel". In the majority of cases, EIPH is not apparent unless an endoscopic examination of the airways is performed following exercise. This is distinguished from other forms of bleeding from the nostrils, called epistaxis.
The mouthpiece is the part of a horse's bit that goes into the mouth of a horse, resting on the bars of the mouth in the sensitive interdental space where there are no teeth. The mouthpiece is possibly the most important determinant in the severity and action of the bit. Some mouthpieces are not allowed in dressage competition.
Recurrent airway obstruction, also known as broken wind, heaves, wind-broke horse, or sometimes by the term usually reserved for humans, chronic obstructive pulmonary disease or disorder (COPD) – it is a respiratory disease or chronic condition of horses involving an allergic bronchitis characterised by wheezing, coughing and laboured breathing.
The respiratory system of the horse is the biological system by which a horse circulates air for the purpose of gaseous exchange.
Lameness is an abnormal gait or stance of an animal that is the result of dysfunction of the locomotor system. In the horse, it is most commonly caused by pain, but can be due to neurologic or mechanical dysfunction. Lameness is a common veterinary problem in racehorses, sport horses, and pleasure horses. It is one of the most costly health problems for the equine industry, both monetarily for the cost of diagnosis and treatment, and for the cost of time off resulting in loss-of-use.
Obligate nasal breathing describes a physiological necessity to breathe through the nose as opposed to breathing through the mouth.
Guttural pouches are large, auditory-tube diverticula that contain between 300 and 600 ml of air. They are present in odd-toed mammals, some bats, hyraxes, and the American forest mouse. They are paired bilaterally just below the ears, behind the skull and connect to the nasopharynx.
Brachycephalic airway obstructive syndrome (BAOS) is a pathological condition affecting short nosed dogs and cats which can lead to severe respiratory distress. There are four different anatomical abnormalities that contribute to the disease, all of which occur more commonly in brachycephalic breeds: an elongated soft palate, stenotic nares, a hypoplastic trachea, and everted laryngeal saccules. Because all of these components make it more difficult to breathe in situations of exercise, stress, or heat, an animal with these abnormalities may be unable to take deep or fast enough breaths to blow off carbon dioxide. This leads to distress and further increases respiratory rate and heart rate, creating a vicious cycle that can quickly lead to a life-threatening situation.
A nasal strip, external nasal dilator strip or nasal dilator strip is a type of adhesive bandage with embedded plastic ribs or splints that is applied across the bridge of the nose and sides of the nostrils, to assist in keeping the airway open. They are believed to make breathing easier and for that reason are used during athletic exertion and as an aid to reduce congestion or to prevent snoring. Various studies have indicated that they do not have a performance-enhancing effect. They are also used by race horse trainers on horses for similar reasons; they are thought to reduce airway resistance and lower the risk of exercise-induced pulmonary hemorrhage (EIPH), plus reduce fatigue and aid post-race recovery.
Equine gastric ulcer syndrome (EGUS) is a common cause of colic and decreased performance in horses. Horses form ulcers in the mucosa of the stomach, leading to pain, decreased appetite, weight loss, and behavioral changes. Treatment generally involves reducing acid production of the stomach and dietary management. Unlike some animals, however, stomach rupture is rare, and the main goal of treating is to reduce pain and improve performance of animals used for showing or racing.
The treatment of equine lameness is a complex subject. Lameness in horses has a variety of causes, and treatment must be tailored to the type and degree of injury, as well as the financial capabilities of the owner. Treatment may be applied locally, systemically, or intralesionally, and the strategy for treatment may change as healing progresses. The end goal is to reduce the pain and inflammation associated with injury, to encourage the injured tissue to heal with normal structure and function, and to ultimately return the horse to the highest level of performance possible following recovery.
Equine welfare helps describe the acceptable conditions of life and use for domesticated horses, in contrast to suffering produced by voluntary or involuntary actions of others, whether through physical abuse, mutilation, neglect, or other forms of ill treatment. Debates about the welfare and abuse of horses are recent. In the nineteenth century, when the sight of a horse dying while working was commonplace, the first wave of awareness was born with the Society for the Prevention of Cruelty to Animals and the publication of the novel Black Beauty in England. France followed suit with the creation of the French League for the Protection of the Horse and the passage of the Grammont Law in 1850. Similar concerns over animal welfare developed in the United States. The debate intensified and extended throughout North America and Europe over the next century, particularly regarding the use of the horse during war, the use of horses as working animals on city streets, sports training, horse slaughter, and conditions of horse breeding and keeping. In the United States, the practice of soring resulted in the passage of the Horse Protection Act of 1970 and various organizations protested against abuses in horse racing and rodeo. In the early twenty-first century, these issues remained in the public eye and new controversies arose, especially about training methods such as Rollkur, problems in the field of endurance riding, stable confinement, and the presence of carriage horses in modern cities such as New York.
