EIPH
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. Epidemiology EIPH often occurs in horses that race at high speeds, with the number of affected race horses increasing in proportion to the speed and intensity of the exercise. It may occur in racing Thoroughbreds (flat racing, steeplechasing or jump racing), American Quarter Horses (incidence of 50–75%), Standardbreds (incidence of 40–60%), Ar ...

Horse
The horse (''Equus ferus caballus'') is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of ''Equus ferus''. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, ''Eohippus'', into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies ''caballus'' are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior. Horses are adapted to run, allowing them to quickly escape predators, and po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endurance Riding
Endurance riding is an equestrian sport based on controlled long-distance races. It is one of the international competitions recognized by the FEI. There are endurance rides worldwide. Endurance rides can be any distance, though they are rarely over 160 km for a one-day competition. There are two main types of long-distance riding, competitive trail riding and endurance rides. In an endurance ride, discussed in this article, the winning horse is the first one to cross the finish line while stopping periodically to pass a veterinary check that deems the animal in good health and fit to continue. As with human marathon running, many riders will participate to improve their horse's personal best performance and consider finishing the distance with a proper vet completion record to be a "win". In the United States, most endurance rides are either 50 or long. Shorter rides, called Limited Distance rides (LD), are organized for new riders to the sport or young horses being ...

Arterial Blood Gas
An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide. An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle, but sometimes the femoral artery in the groin or another site is used. The blood can also be drawn from an arterial catheter. An ABG test measures the blood gas tension values of the arterial partial pressure of oxygen (PaO2), and the arterial partial pressure of carbon dioxide (PaCO2), and the blood's pH. In addition, the arterial oxygen saturation (SaO2) can be determined. Such information is vital when caring for patients with critical illnesses or respiratory disease. Therefore, the ABG test is one of the most common tests performed on patients in intensive-care units. In other levels of care, pulse oximetry plus transcutaneous carbon-dioxide measurement is a less invasive, alternative method of obtaining similar ...

Epistaxis
A nosebleed, also known as epistaxis, is bleeding from the nose. Blood can flow down into the stomach, and cause nausea and vomiting. In more severe cases, blood may come out of both nostrils. Rarely, bleeding may be so significant that low blood pressure occurs. Blood may also come up the nasolacrimal duct and out from the eye. Risk factors include trauma, including putting the finger in the nose, blood thinners, high blood pressure, alcoholism, seasonal allergies, dry weather, and inhaled corticosteroids. There are two types: anterior, which is more common; and posterior, which is less common but more serious. Anterior nosebleeds generally occur from Kiesselbach's plexus while posterior bleeds generally occur from the sphenopalatine artery. The diagnosis is by direct observation. Prevention may include the use of petroleum jelly in the nose. Initially, treatment is generally the application of pressure for at least five minutes over the lower half of the nose. If this is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertebrate Trachea
The trachea, also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi. At the top of the trachea the cricoid cartilage attaches it to the larynx. The trachea is formed by a number of horseshoe-shaped rings, joined together vertically by overlying ligaments, and by the trachealis muscle at their ends. The epiglottis closes the opening to the larynx during swallowing. The trachea begins to form in the second month of embryo development, becoming longer and more fixed in its position over time. It is epithelium lined with column-shaped cells that have hair-like extensions called cilia, with scattered goblet cells that produce protective mucins. The trachea can be affected by inflammation or infection, usually as a result of a viral illness affecting other parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geldings
A gelding is a castrated male horse or other equine, such as a pony, donkey or a mule. Castration, as well as the elimination of hormonally driven behavior associated with a stallion, allows a male equine to be calmer and better-behaved, making the animal quieter, gentler and generally more suitable as an everyday working animal. The gerund and participle "gelding" and the infinitive "to geld" refer to the castration procedure itself. Etymology The verb "to geld" comes from the Old Norse , from the adjective 'barren'. The noun "gelding" is from the Old Norse . History The Scythians are thought to have been the first people to geld their horses. They valued geldings as war horses because they were quiet, lacked mating urges, were less prone to call out to other horses, were easier to keep in groups, and were less likely to fight with one another. Reasons for gelding A male horse is often gelded to make him better-behaved and easier to control. Gelding can also remove lower-qua ...

Mares
A mare is an adult female horse or other equine. In most cases, a mare is a female horse over the age of three, and a filly is a female horse three and younger. In Thoroughbred horse racing, a mare is defined as a female horse more than four years old. The word can also be used for other female equine animals, particularly mules and zebras, but a female donkey is usually called a "jenny". A broodmare is a mare used for breeding. A horse's female parent is known as its dam. Reproductive cycle Mares carry their young (called foals) for approximately 11 months from conception to birth. (Average range 320–370 days.)Ensminger, M. E. ''Horses and Horsemanship: Animal Agriculture Series.'' Sixth Edition. Interstate Publishers, 1990. p. 156 Usually just one young is born; twins are rare. When a domesticated mare foals, she nurses the foal for at least four to six months before it is weaned, though mares in the wild may allow a foal to nurse for up to a year. The estrous cycle, ...

Stallions
A stallion is a male horse that has not been gelded (castrated). Stallions follow the conformation and phenotype of their breed, but within that standard, the presence of hormones such as testosterone may give stallions a thicker, "cresty" neck, as well as a somewhat more muscular physique as compared to female horses, known as ''mares'', and castrated males, called ''geldings''. Temperament varies widely based on genetics, and training, but because of their instincts as herd animals, they may be prone to aggressive behavior, particularly toward other stallions, and thus require careful management by knowledgeable handlers. However, with proper training and management, stallions are effective equine athletes at the highest levels of many disciplines, including horse racing, horse shows, and international Olympic competition. "Stallion" is also used to refer to males of other equids, including zebras and donkeys. Herd behavior Contrary to popular myths, many stallions do not ...

Cutting (sport)
Cutting is a western-style equestrian competition in which a horse and rider work together before a judge or panel of judges to demonstrate the horse's athleticism and ability to handle cattle. Modern competition utilizes a minute performance, called a "run." Each contestant is assisted by four helpers: two are designated as turnback riders, who help to keep cattle from running off to the back of the arena, the other two are designated as herd holders to keep the cattle bunched together and prevent potential strays from escaping into the work area. Cutting cattle are typically young steers and heifers that customarily range in size from . They usually are of Angus or Hereford lineage though may be a mix of crossbred beef cattle, including Charolais or Brahman lineage. A contestant is required to make at least two cuts from the herd, one of which must be a cut from deep inside the herd while the other(s) can be peeled from the edges. Once the selected cow has been driven clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reining
Reining is a western riding competition for horses where the riders guide the horses through a precise pattern of circles, spins, and stops. All work is done at the lope (a version of the horse gait more commonly known worldwide as the canter), or the gallop (the fastest of the horse gaits). Originating from working cattle, reining is often described as a Western form of dressage riding, as it requires the horse to be responsive and in tune with its rider, whose aids should not be easily seen, and judges the horse on its ability to perform a set pattern of movements. The horse should be willingly guided or controlled with little or no apparent resistance and dictated to completely. A horse that pins his ears, conveying a threat to his rider, refuses to go forward, runs sideways, bounces his rear, wrings his tail in irritation or displays an overall poor attitude is not being guided willingly, and is judged accordingly.

Barrel Racing
Barrel racing is a rodeo event in which a horse and rider attempt to run a cloverleaf pattern around preset barrels in the fastest time. In collegiate and professional ranks, it is usually a women's event, though both sexes compete at amateur and youth levels. It requires a combination of the horse's athletic ability and the horsemanship skills of a rider in order to safely and successfully maneuver the horse around three barrels placed in a triangle pattern within a large arena. History Barrel racing originally developed as an event for women. In early barrel racing, the pattern alternated between a figure-eight and a cloverleaf pattern. The figure-eight was eventually dropped in favor of the more difficult cloverleaf. It is believed that competitive barrel racing was first held in Texas. The Women's Professional Rodeo Association (WPRA) was founded in 1948 by a group of women from Texas who were trying to find a place for women in the wider sport of rodeo. When it began, th ...
