Herd behavior
![Horsescd1l-095](https://upload.wikimedia.org/wikipedia/commons/2/24/Horsescd1l-095.jpg)
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

s 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
A filly is a female horse that is too young to be called a mare. There are two specific definitions in use:

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.
![Flehmendes Pferd 32 c](https://upload.wikimedia.org/wikipedia/commons/4/44/Flehmendes_Pferd_32_c.jpg)
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

may also contain older stallions who have lost their herd in a challenge.
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,

Management and handling of domesticated stallions

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
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is al ...
. 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.[
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. 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 ]instinct

s 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

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
Stable vices are stereotypies of equines, especially horses. They are usually undesirable habits that often develop as a result of being confined in a stable with boredom, hunger, isolation, excess energy, or insufficient exercise. They present ...

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.
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.
As an example, in the New Forest
The New Forest is one of the largest remaining tracts of unenclosed pasture land, heathland and forest in Southern England, covering southwest Hampshire and southeast Wiltshire. It was proclaimed a royal forest by William the Conqueror, featu ...
, 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. 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.
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.
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
A stable is a building in which livestock, especially horses, are kept. It most commonly means a building that is divided into separate stalls for individual animals and livestock. There are many different types of stables in use today; the ...

. 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

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.[
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

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. 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[ and behave better if this is done.] 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.

to be performed on a horse of almost any age with relatively few risks.
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.[ They are also more widely accepted.

Ridglings
A ridgling
A ridgling (also spelled ridgeling), or rig, is a cryptorchid; a male animal with one or both testicles undescended, usually describing a ram, bull, or male horse, but cryptorchidism also can be an issue in dogs and cats. Because the heat inside t ...

, 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". 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.
