Stallion

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.

The term "stallion" dates from the era of Henry VII, who passed a number of laws relating to the breeding and export of horses in an attempt to improve the British stock, under which it was forbidden to allow uncastrated male horses to be turned out in fields or on the commons; they had to be "kept within bounds and tied in stalls." (The term "stallion" for an uncastrated male horse dates from this time; stallion = stalled one.)[1] "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 live with a harem of mares. Nor, in natural settings, do they fight each other to the death in competition for mares. Being social animals, stallions who are not able to find or win a harem of mares usually band together in stallions-only "bachelor" groups which are composed of stallions of all ages. Even with a band of mares, the stallion is not the leader of a herd but defends and protects the herd from predators and other stallions. The leadership role in a herd is held by a mare, known colloquially as the "lead mare" or "boss mare." The mare determines the movement of the herd as it travels to obtain food, water, and shelter. She also determines the route the herd takes when fleeing from danger. When the herd is in motion, the dominant stallion herds the straggling members closer to the group and acts as a "rear guard" between the herd and a potential source of danger. When the herd is at rest, all members share the responsibility of keeping watch for danger. The stallion is usually on the edge of the group, to defend the herd if needed.

There is usually one dominant mature stallion for every mixed-sex herd of horses. The dominant stallion in the herd will tolerate both sexes of horses while young, but once they become sexually mature, often as yearlings or two-year-olds, the stallion will drive both colts and fillies from the herd. Colts may present competition for the stallion, but studies suggest that driving off young horses of both sexes may also be an instinctive behavior that minimizes the risk of inbreeding within the herd, as most young are the offspring of the dominant stallion in the group. In some cases, a single younger mature male may be tolerated on the fringes of the herd. One theory is that this young male is considered a potential successor, as in time the younger stallion will eventually drive out the older herd stallion.

Fillies usually soon join a different band with a dominant stallion different from the one that sired them. Colts or young stallions without mares of their own usually form small, all-male, "bachelor bands" in the wild. Living in a group gives these stallions the social and protective benefits of living in a herd. A bachelor herd may also contain older stallions who have lost their herd in a challenge.[2]

Other stallions may directly challenge a herd stallion, or may simply attempt to "steal" mares and form a new, smaller herd. In either case, if the two stallions meet, there rarely is a true fight; more often there will be bluffing behavior and the weaker horse will back off. Even if a fight for dominance occurs, rarely do opponents hurt each other in the wild because the weaker combatant has a chance to flee. Fights between stallions in captivity may result in serious injuries; fences and other forms of confinement make it more difficult for the losing animal to safely escape. In the wild, feral stallions have been known to steal or mate with domesticated mares.

A stallion's secondary characteristics include heavier muscling for a given breed than is seen in mares or geldings, often with considerable development along the crest of the neck, as shown in this image.

The stallion's reproductive system is responsible for his sexual behavior and secondary sex characteristics (such as a large crest). The external genitalia comprise:

  • the testes, which are suspended horizontally within the scrotum. The testes of an average stallion are ovoids 8 to 12 cm (3.1 to 4.7 in) long, 6 to 7 cm (2.4 to 2.8 in) high by 5 cm (2.0 in) wide;[3]
  • the penis, within the prepuce, also known as the "sheath".[4][5] Stallions have a vascular penis. When non-erect, it is quite flaccid and contained within the prepuce (foreskin, or sheath). The retractor penis muscle is relatively underdeveloped. Erection and protrusion take place gradually, by the increasing tumescence of the erectile vascular tissue in the corpus cavernosum penis.[6] When not erect, the penis is housed within the prepuce, 50 cm (20 in) long and 2.5 to 6 cm (0.98 to 2.36 in) in diameter with the distal end 15 to 20 cm (5.9 to 7.9 in). The retractor muscle contracts to retract the penis into the sheath and relaxes to allow the penis to extend from the sheath. When erect, the penis doubles in length and thickness and the glans increases by 3 to 4 times. The urethra opens within the urethral fossa, a small pouch at the distal end of the glans.[7] A structure called the urethral process projects beyond the glans.[8]

The internal genitalia comprise the accessory sex glands, which include the vesicular glands, the prostate gland and the bulbourethral glands.[9] These contribute fluid to the semen at ejaculation, but are not strictly necessary for fertility.[3][10]

Management and handling of domesticated stallions

Arabe
Even well-trained stallions require firm and consistent handling by experienced individuals.

Domesticated stallions are trained and managed in a variety of ways, depending on the region of the world, the owner's philosophy, and the individual stallion's temperament. In all cases, however, stallions have an inborn tendency to attempt to dominate both other horses and human handlers, and will be affected to some degree by proximity to other horses, especially mares in heat. They must be trained to behave with respect toward humans at all times or else their natural aggressiveness, particularly a tendency to bite, may pose a danger of serious injury.[2]

For this reason, regardless of management style, stallions must be treated as individuals and should only be handled by people who are experienced with horses and thus recognize and correct inappropriate behavior before it becomes a danger.[11] While some breeds are of a more gentle temperament than others, and individual stallions may be well-behaved enough to even be handled by inexperienced people for short periods of time, common sense must always be used. Even the most gentle stallion has natural instincts that may overcome human training. As a general rule, children should not handle stallions, particularly in a breeding environment.

Management of stallions usually follows one of the following models: confinement or "isolation" management, where the stallion is kept alone, or in management systems variously called "natural", "herd", or "pasture" management where the stallion is allowed to be with other horses. In the "harem" model, the stallion is allowed to run loose with mares akin to that of a feral or semi-feral herd. In the "bachelor herd" model, stallions are kept in a male-only group of stallions, or, in some cases, with stallions and geldings. Sometime stallions may periodically be managed in multiple systems, depending on the season of the year.

The advantage of natural types of management is that the stallion is allowed to behave "like a horse" and may exhibit fewer stable vices. In a harem model, the mares may "cycle" or achieve estrus more readily. Proponents of natural management also assert that mares are more likely to "settle" (become pregnant) in a natural herd setting. Some stallion managers keep a stallion with a mare herd year-round, others will only turn a stallion out with mares during the breeding season.[12]

In some places, young domesticated stallions are allowed to live separately in a "bachelor herd" while growing up, kept out of sight, sound or smell of mares. A Swiss study demonstrated that even mature breeding stallions kept well away from other horses could live peacefully together in a herd setting if proper precautions were taken while the initial herd hierarchy was established.[13]

As an example, in the New Forest, England, breeding stallions run out on the open Forest for about two to three months each year with the mares and youngstock. On being taken off the Forest, many of them stay together in bachelor herds for most of the rest of the year.[14][15][16] New Forest stallions, when not in their breeding work, take part on the annual round-ups, working alongside mares and geldings, and compete successfully in many disciplines.[17][18]

There are drawbacks to natural management, however. One is that the breeding date, and hence foaling date, of any given mare will be uncertain. Another problem is the risk of injury to the stallion or mare in the process of natural breeding, or the risk of injury while a hierarchy is established within an all-male herd. Some stallions become very anxious or temperamental in a herd setting and may lose considerable weight, sometimes to the point of a health risk. Some may become highly protective of their mares and thus more aggressive and dangerous to handle. There is also a greater risk that the stallion may escape from a pasture or be stolen. Stallions may break down fences between adjoining fields to fight another stallion or mate with the "wrong" herd of mares, thus putting the pedigree of ensuing foals in question.[19]

Aggressive and even violent behavior between stallions not habitually living together or in the presence of mares adds to the challenges in stallion management.

Provided with sufficient space and food with no distractions from mares in estrus, even stallions previously used for breeding may coexist peacefully. Not all individuals are suited for this kind of arrangement, however.

The other general method of managing stallions is to confine them individually, sometimes in a small pen or corral with a tall fence, other times in a stable, or, in certain places, in a small field (or paddock) with a strong fence. The advantages to individual confinement include less of a risk of injury to the stallion or to other horses, controlled periods for breeding mares, greater certainty of what mares are bred when, less risk of escape or theft, and ease of access by humans. Some stallions are of such a temperament, or develop vicious behavior due to improper socialization or poor handling, that they must be confined and cannot be kept in a natural setting, either because they behave in a dangerous manner toward other horses, or because they are dangerous to humans when loose.

The drawbacks to confinement vary with the details of the actual method used, but stallions kept out of a herd setting require a careful balance of nutrition and exercise for optimal health and fertility. Lack of exercise can be a serious concern; stallions without sufficient exercise may not only become fat, which may reduce both health and fertility, but also may become aggressive or develop stable vices due to pent-up energy. Some stallions within sight or sound of other horses may become aggressive or noisy, calling or challenging other horses. This sometimes is addressed by keeping stallions in complete isolation from other animals.

However, complete isolation has significant drawbacks; stallions may develop additional behavior problems with aggression due to frustration and pent-up energy. As a general rule, a stallion that has been isolated from the time of weaning or sexual maturity will have a more difficult time adapting to a herd environment than one allowed to live close to other animals. However, as horses are instinctively social creatures, even stallions are believed to benefit from being allowed social interaction with other horses, though proper management and cautions are needed.[13]

Some managers attempt to compromise between the two methods by providing stallions daily turnout by themselves in a field where they can see, smell, and hear other horses. They may be stabled in a barn where there are bars or a grille between stalls where they can look out and see other animals. In some cases, a stallion may be kept with or next to a gelding or a nonhorse companion animal such as a goat, a gelded donkey, a cat, or other creature.

Properly trained stallions can live and work close to mares and to one another. Examples include the Lipizzan stallions of the Spanish Riding School in Vienna, Austria, where the entire group of stallions live part-time in a bachelor herd as young colts, then are stabled, train, perform, and travel worldwide as adults with few if any management problems. However, even stallions who are unfamiliar with each other can work safely in reasonable proximity if properly trained; the vast majority of Thoroughbred horses on the racetrack are stallions, as are many equine athletes in other forms of competition. Stallions are often shown together in the same ring at horse shows, particularly in halter classes where their conformation is evaluated. In horse show performance competition, stallions and mares often compete in the same arena with one another, particularly in Western and English "pleasure"-type classes where horses are worked as a group. Overall, stallions can be trained to keep focused on work and maybe brilliant performers if properly handled.[20]

A breeding stallion is more apt to present challenging behavior to a human handler than one who has not bred mares, and stallions may be more difficult to handle in spring and summer, during the breeding season, than during the fall and winter. However, some stallions are used for both equestrian uses and for breeding at the same general time of year. Though compromises may need to be made in expectations for both athletic performance and fertility rate, well-trained stallions with good temperaments can be taught that breeding behavior is only allowed in a certain area, or with certain cues, equipment, or with a particular handler.[21][22] However, some stallions lack the temperament to focus on work if also breeding mares in the same general time period, and therefore are taken out of competition either temporarily or permanently to be used for breeding. When permitted by a breed registry, use of artificial insemination is another technique that may reduce behavior problems in stallions.

Cultural views of stallions

Maestoso Basowizza & Oberbereiter Hausberger
Stallions are capable of achieving a high level of discipline and training.

Attitudes toward stallions vary between different parts of the world. In some parts of the world, the practice of gelding is not widespread and stallions are common. In other places, most males are gelded and only a few stallions are kept as breeding stock. Horse breeders who produce purebred bloodstock often recommend that no more than the top 10 percent of all males be allowed to reproduce, to continually improve a given breed of horse.

People sometimes have inaccurate beliefs about stallions, both positive and negative. Some beliefs are that stallions are always mean and vicious or uncontrollable, other beliefs are that misbehaving stallions should be allowed to misbehave because they are being "natural", "spirited" or "noble." In some cases, fed by movies and fictional depictions of horses in literature, some people believe a stallion can bond to a single human individual to the exclusion of all others. However, like many other misconceptions, there is only partial truth to these beliefs. Some, though not all stallions can be vicious or hard to handle, occasionally due to genetics, but usually due to improper training. Others are very well-trained and have excellent manners. Misbehaving stallions may look pretty or be exhibiting instinctive behavior, but it can still become dangerous if not corrected. Some stallions do behave better for some people than others, but that can be true of some mares and geldings, as well.

In some parts of Asia and the Middle East, the riding of stallions is widespread, especially among male riders. The gelding of stallions is unusual, viewed culturally as either unnecessary or unnatural. In areas where gelding is not widely practised, stallions are still not needed in numbers as great as mares, and so many will be culled, either sold for horsemeat or simply sold to traders who will take them outside the area. Of those that remain, many will not be used for breeding purposes.

In Europe, Australia, and the Americas, keeping stallions is less common, primarily confined to purebred animals that are usually trained and placed into competition to test their quality as future breeding stock. The majority of stallions are gelded at an early age and then trained for use as everyday working or riding animals.

Geldings

If a stallion is not to be used for breeding, gelding the male horse will allow it to live full-time in a herd with both males and females, reduce aggressive or disruptive behavior, and allow the horse to be around other animals without being seriously distracted.[23] If a horse is not to be used for breeding, it can be gelded prior to reaching sexual maturity. A horse gelded young may grow taller[23] and behave better if this is done.[24] Older stallions that are sterile or otherwise no longer used for breeding may also be gelded and will exhibit calmer behavior, even if previously used for breeding. However, they are more likely to continue stallion-like behaviors than horses gelded at a younger age, especially if they have been used as a breeding stallion. Modern surgical techniques allow castration to be performed on a horse of almost any age with relatively few risks.[25]

In most cases, particularly in modern industrialized cultures, a male horse that is not of sufficient quality to be used for breeding will have a happier life without having to deal with the instinctive, hormone-driven behaviors that come with being left intact. Geldings are safer to handle and present fewer management problems.[24] They are also more widely accepted. Many boarding stables will refuse clients with stallions or charge considerably more money to keep them. Some types of equestrian activity, such as events involving children, or clubs that sponsor purely recreational events such as trail riding, may not permit stallions to participate.

However, just as some pet owners may have conflicting emotions about neutering a male dog or cat, some stallion owners may be unsure about gelding a stallion. One branch of the animal rights community maintains that castration is mutilation and damaging to the animal's psyche.[26]

Ridglings

A ridgling or "rig" is a cryptorchid, a stallion which has one or both testicles undescended. If both testicles are not descended, the horse may appear to be a gelding, but will still behave like a stallion. A gelding that displays stallion-like behaviors is sometimes called a "false rig".[27] In many cases, ridglings are infertile, or have fertility levels that are significantly reduced. The condition is most easily corrected by gelding the horse. A more complex and costly surgical procedure can sometimes correct the condition and restore the animal's fertility, though it is only cost-effective for a horse that has very high potential as a breeding stallion. This surgery generally removes the non-descended testicle, leaving the descended testicle, and creating a horse known as a monorchid stallion. Keeping cryptorchids or surgically-created monorchids as breeding stallions is controversial, as the condition is at least partially genetic and some handlers claim that cryptorchids tend to have greater levels of behavioral problems than normal stallions.[28][29]

American Quarter Horse Hall of Fame

The American Quarter Horse Hall of Fame and Museum was created by the American Quarter Horse Association (AQHA), based in Amarillo, Texas. Ground breaking construction of the Hall of Fame Museum began in 1989.The distinction is earned by people and horses who have contributed to the growth of the American Quarter Horse and "have been outstanding over a period of years in a variety of categories". In 1982, Bob Denhardt and Ernest Browning were the first individuals to receive the honor of being inducted into the AQHA Hall of Fame. In 1989, Wimpy P-1, King P-234, Leo and Three Bars were the first horses inducted into the AQHA Hall of Fame.

Foundation stock

Foundation bloodstock or foundation stock are animals that are the progenitors, or foundation, of a new breed (or crossbreed or hybrid), or of a given bloodline within such. Although usually applied to individual animals, a group of animals may be referred to collectively as foundation bloodstock when one distinct population (such a breed or a breed group) provides part of the underlying genetic base for a new distinct population.

The term is particularly common in older breeds for which a written breed registry was not created until after the breed phenotype was well established. However, many modern breeds can be traced to specific, named foundation animals.

The terms for foundation parents differ by sex, most commonly foundation sire for the father, and foundation dam for the mother. Depending upon the species in question, more specialized terms may be used, such as foundation mare for female horses, or foundation queen for female cats. Less common is foundation bitch for female dogs.

The first generation progeny of foundation stock of a hybrid are referred to as F1 hybrid animals, the second generation as F2, and so forth, usually through F4.

Gelding

A gelding is a castrated horse or other equine, such as a donkey or a mule. Castration, as well as the elimination of hormonally-driven behavior associated with a stallion, allows a male horse to be calmer and better-behaved, making the animal quieter, gentler and potentially more suitable as an everyday working animal. The gerund and participle "gelding" and the infinitive "to geld" refer to the castration procedure itself.

Henry George Carey Jr. (May 16, 1921 – December 27, 2012) was an American actor. He appeared in more than 90 films, including several John Ford Westerns, as well as numerous television series.

Horse breeding

Horse breeding is reproduction in horses, and particularly the human-directed process of selective breeding of animals, particularly purebred horses of a given breed. Planned matings can be used to produce specifically desired characteristics in domesticated horses. Furthermore, modern breeding management and technologies can increase the rate of conception, a healthy pregnancy, and successful foaling.

Mare

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.

An uncastrated adult male horse is called a stallion and a castrated male is a gelding. Occasionally, the term "horse" is used to designate only a male horse.

Sikorsky CH-53E Super Stallion

The Sikorsky CH-53E Super Stallion is a heavy-lift helicopter operated by the United States military. As the Sikorsky S-80 it was developed from the CH-53 Sea Stallion, mainly by adding a third engine, adding a seventh blade to the main rotor and canting the tail rotor 20 degrees. It was built by Sikorsky Aircraft for the United States Marine Corps. The less common MH-53E Sea Dragon fills the United States Navy's need for long range minesweeping or Airborne Mine Countermeasures (AMCM) missions, and perform heavy-lift duties for the Navy. Under development is the Sikorsky CH-53K King Stallion, which has new engines, new composite material rotor blades, and a wider aircraft cabin; this is to replace the CH-53E.

Sikorsky CH-53K King Stallion

The Sikorsky CH-53K King Stallion is a large, heavy-lift cargo helicopter currently being developed by Sikorsky Aircraft for the United States Marine Corps (USMC). The design features three 7,500 shp (5,590 kW) engines, new composite rotor blades, and a wider aircraft cabin than previous CH-53 variants. It will be the largest and heaviest helicopter in the U.S. military. The USMC plans to receive 200 helicopters at a total cost of $25 billion. Ground Test Vehicle (GTV) testing started in April 2014; flight testing began with the maiden flight on 27 October 2015. In May 2018 the first CH-53K was delivered to the Marine Corps.

Sikorsky CH-53 Sea Stallion

The CH-53 Sea Stallion is the most common name for the Sikorsky S-65 family of heavy-lift transport helicopters. Originally developed for use by the United States Marine Corps, it is in service with Germany, Iran, Israel, and Mexico. The United States Air Force operated the HH-53 "Super Jolly Green Giant" during the late– and post–Vietnam-War era, updating most of them as the MH-53 Pave Low.

The dimensionally-similar CH-53E Super Stallion is a heavier-lifting, improved version designated S-80E by Sikorsky. Its third engine makes it more powerful than the Sea Stallion, which it has replaced in the heavy-lift mission.

Zebroid

A zebroid is the offspring of any cross between a zebra and any other equine: essentially, a zebra hybrid. In most cases, the sire is a zebra stallion. Offspring of a donkey sire and zebra dam called a donkra or zebra hinny and offspring of a horse sire and a zebra dam called a hebra do exist, but are rare and are usually sterile and infertile. Zebroids have been bred since the 19th century. Charles Darwin noted several zebra hybrids in his works.
