How old is a filly when she officially becomes a mare?
"acknowledge the age of an old man? And what is it which is called righteousness? The fact of a man's being old? Or the fact of our giving honour to his age?' Other early ""A white horse is not a horse"" references are found in the ""Hanfeizi"" (32), ""Mozi"" (11B), and ""Zhanguoce"" (4). When a white horse is not a horse When A White Horse Is Not A Horse (), also known as the White Horse Dialogue (), is a famous paradox in Chinese philosophy. Gongsun Long wrote this circa 300 BC dialectic analysis of the question 'Is ""white horse"
"at longer distances. Fillies are sexually mature by age two and are sometimes bred at that age, but generally should not be bred until they themselves have stopped growing, usually by age four or five. A healthy, well-managed mare can produce a foal every year into her twenties, though not all breeders will breed a mare every year. In addition, many mares are kept for riding and so are not bred annually, as a mare in late pregnancy or nursing a foal is not able to perform at as athletic a standard as one who is neither pregnant nor lactating."
"cycle of a mare occurs roughly every 19–22 days and occurs from early spring into autumn. Most mares enter an ""anestrus"" period during the winter and thus do not cycle in this period. Foals are generally weaned from their mothers between four and six months of age. Horses, particularly colts, sometimes are physically capable of reproduction at about 18 months, but domesticated horses are rarely allowed to breed before the age of three, especially females. Horses four years old are considered mature, although the skeleton normally continues to develop until the age of six; maturation also depends on the horse's"
"be most difficult for the foal to survive. However, for most competitive purposes, foals are given an official ""birthday"" of January 1 (August 1 in the Southern hemisphere), and many breeders want foals to be born as early in the year as possible. Therefore, many breeding farms begin to put mares ""under lights"" in late winter in order to bring them out of anestrus early and allow conception to occur in February or March. One exception to this general rule is the field of endurance riding, which requires horses to be 60 true calendar months old (5 years) before competing"
"a stallion and a castrated male is a gelding. Occasionally, the term ""horse"" is used to designate only a male horse. Mares carry their young (called foals) for approximately 11 months from conception to birth. (Average range 320–370 days.) 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, also known as ""season"" or ""heat"" of a mare occurs roughly every 19–22"
"tend to be shy and live in small, territorial herds or harems numbering between 10–30 mares. They are able to predict the weather conditions, moving into the valleys in anticipation of bad weather and upland when high pressure builds. During the autumn, the herd breaks up into smaller groups of 5–10 horses and re-unite in spring. Foals mature quickly. Fillies become fertile at age 2, normally mate at age 3 and give birth at age 4, which is also the age of maturity for males. Foals, like those of other breeds, are born after 11 months during spring/early summer and"
"as ""to foal"". A newborn horse is ""foaled"". After a horse is one year old, it is no longer a foal, and is a ""yearling"". There are no special age-related terms for young horses older than yearlings. When young horses reach breeding maturity, the terms change: a filly over three (four in horse racing) is called a mare, and a colt over three is called a stallion. A castrated male horse is called a gelding regardless of age; however, colloquially, the term ""gelding colt"" is sometimes used until a young gelding is three or four. (There is no specific term"
"lying down, with younger horses tending to sleep significantly more than adults. Female horses, called mares, carry their young for approximately 11 months, and a young horse, called a foal, can stand and run shortly following birth. Most domesticated horses begin training under saddle or in harness between the ages of two and four. They reach full adult development by age five, and have an average lifespan of between 25 and 30 years. Horse breeds are loosely divided into three categories based on general temperament: spirited ""hot bloods"" with speed and endurance; ""cold bloods"", such as draft horses and some"
"do not receive their papers until they are presented at a local foal show, at which judges may exclude any foal if it is markedly off-type. Along with their papers, the foals receive a brand on the left hind leg, just behind the stifle. Foal inspections also give an early indication of the quality of the sire, as well as which mares match best with him. At the age of 3, fillies may be upgraded from the foal register to the herd book through a process called ""Stutbuchaufnahmen"" or ""Marebook Recording"". There are several levels of mare book based on"
"young, and consider it far safer than trying to tame a semi-feral adult-sized horse. In either case, foals that have not bonded to their mothers will have difficulty in pasture. The mare will find it more difficult to teach the foal to follow her. Other horses can have difficulty communicating with the foal and may ostracise it due to speaking a different ""language"". It can be difficult to lead a foal that has never even been led by its dam. Horses are not fully mature until the age of four or five, but most are started as working animals much"
"Colt (horse) A colt is a male horse, usually below the age of four years. The term ""colt"" only describes young male horses and is not to be confused with foal, which is a horse of either sex less than one year of age. Similarly, a yearling is a horse of either sex between the ages of one and two. A young female horse is called a filly, and a mare once she is an adult animal. In horse racing, particularly for Thoroughbreds in the United Kingdom, a colt is defined as an uncastrated male from the age of two"
"grass and grain alongside the mare at about 4 weeks old; by 10–12 weeks the foal requires more nutrition than the mare's milk can supply. Foals are typically weaned at 4–8 months of age, although in the wild a foal may nurse for a year. Beyond the appearance and conformation of a specific type of horse, breeders aspire to improve physical performance abilities. This concept, known as matching ""form to function,"" has led to the development of not only different breeds, but also families or bloodlines within breeds that are specialists for excelling at specific tasks. For example, the Arabian"
"old is called a weanling. Mare's milk is not a significant source of nutrients for the foal after about four months, though it does no harm to a healthy mare for a foal to nurse longer and may be of some psychological benefit to the foal. A mare that is both nursing and pregnant will have increased nutritional demands made upon her in the last months of pregnancy, and therefore most domesticated foals are weaned sometime in the autumn in the Northern Hemisphere if the mare is to be bred again the next season. Weanlings are not capable of reproduction."
"distinct from those bred for work under saddle, which are carefully selected for their ability to perform the traditional Icelandic gaits. Others are bred solely for horsemeat. Some breeders focus on favored coat colors. Members of the breed are not usually ridden until they are four years old, and structural development is not complete until age seven. Their most productive years are between eight and eighteen, although they retain their strength and stamina into their twenties. An Icelandic mare that lived in Denmark reached a record age of 56, while another horse, living in Great Britain, reached the age of"
"the formation of the endometrial cups, and true placentation (formation of the placenta) is not initiated until about day 40-45 and not completed until about 140 days of pregnancy. The fetus sex can be determined by day 70 of the gestation using ultrasound. Halfway through gestation the fetus is the size of between a rabbit and a beagle. The most dramatic fetal development occurs in the last 3 months of pregnancy when 60% of fetal growth occurs. Colts are carried on average about 4 days longer than fillies. Domestic mares receive specific care and nutrition to ensure that they and"
"11 to 13 months, and most mares come into estrus again within a few days after foaling, depending on conditions. Usually, only a single foal is born, which is capable of running within an hour. Within a few weeks, foals attempt to graze, but may continue to nurse for 8–13 months. Species in arid habitats, like Grévy's zebra, have longer nursing intervals and do not drink water until they are three months old. Among harem-holding species, foals are cared for mostly by their mothers, but if threatened by predators, the entire group works together to protect all the young. The"
"21 days. As the days shorten, the mare returns to a period when she is not sexually receptive, known as anestrus. Anestrus – occurring in the majority of, but not all, mares – prevents the mare from conceiving in the winter months, as that would result in her foaling during the harshest part of the year, a time when it would be most difficult for the foal to survive. This cycle contains 2 phases: Depending on breed, on average, 16% of mares have double ovulations, allowing them to twin, though this does not affect the length of time of estrus"
"local people have rights to graze livestock, including their ponies. Generally the mares are turned out for the whole year, living in small groups, which often consist of an older mare, several of her female offspring, and their foals (which are born in spring, after a pregnancy of eleven months). Small numbers of stallions are allowed to join the mares for a few weeks in spring or early summer. Each stallion then gathers a harem of mares and their foals to form a larger group of up to twenty or so. The foals and mares are rounded up in autumn,"
"for a spayed mare other than a ""spayed mare"".) Horses that mature at a small stature are called ponies and occasionally confused with foals. However, body proportions are very different. An adult pony can be ridden and put to work, but a foal, regardless of stature, is too young to be ridden or used as a working animal. Foals, whether they grow up to be horse or pony-sized, can be distinguished from adult horses by their extremely long legs and small, slim bodies. Their heads and eyes also exhibit juvenile characteristics. Although ponies exhibit some neoteny with the wide foreheads"
"Yearling (horse) A yearling is a young horse either male or female that is between one and two years old. Yearlings are comparable in development to a very early adolescent and are not fully mature physically. While they may be in the earliest stages of sexual maturity, they are considered too young to be breeding stock. Yearlings may be further defined by sex, using the term ""colt"" to describe any male horse under age four, and filly for any female under four. Generally, the training of yearlings consists of basic gentling on the ground; most are too young to be"
"the age of 20 and some even over 25. No horse has ever been injured during the dart-administered treatments, although there is a 0.2 percent rate of abscess at the injection site, which normally heals within two weeks. Each mare between two and four years old is given contraceptives, and treatment is then withdrawn until she produces a foal. Once she has produced enough foals to be well represented genetically within the herd, she is placed on a yearly treatment plan until her death. After the introduction of the contraceptive, herd numbers continued to rise to a high of 175"
"the feet of the foal appear to full delivery is often only about 15 to 20 minutes. Once the foal is born, the mare will lick the newborn foal to clean it and help blood circulation. In a very short time, the foal will attempt to stand and get milk from its mother. A foal should stand and nurse within the first hour of life. To create a bond with her foal, the mare licks and nuzzles the foal, enabling her to distinguish the foal from others. Some mares are aggressive when protecting their foals, and may attack other horses"
"and the neck is medium to short, thick, sloping and well connected to shoulders, which are well-sloped. The chest is broad and deep, the back tends to be long, and the croup is slightly sloping. The hoof is wide, but not as strong as it should. The most common dresses are black, bay and gray dress being united principle. Mares mature at two years old and are able to reproduce at three. They can give birth to 12 or 13 foals in their lives. The fertility rate is 70%, but can go up to 80 or even 90% with appropriate"
"British Champions Fillies and Mares Stakes The British Champions Fillies & Mares Stakes is a Group 1 flat horse race in Great Britain open to fillies and mares aged three years or older. It is run over a distance of 1 mile 3 furlongs and 211 yards (2,406 metres) as part of British Champions Day at Ascot in October. The event was established in 1946 and was originally called the Princess Royal Stakes. It was named after the Princess Royal at that time, Princess Mary. For a period it took place in September, and it later moved to October. The"
"ages: In horse racing, these definitions may differ: For example, in the British Isles, Thoroughbred horse racing defines colts and fillies as less than five years old. However, Australian Thoroughbred racing defines colts and fillies as less than four years old. The height of horses is measured at the highest point of the withers, where the neck meets the back. This point is used because it is a stable point of the anatomy, unlike the head or neck, which move up and down in relation to the body of the horse. In English-speaking countries, the height of horses is often"
"their common offspring. Offspring stay in the family group until they are no longer dependent, usually at two or three years old. Bachelor stallions, and sometimes old stallions, join bachelor groups. Family groups can join together to form a herd that moves together. The patterns of their daily lives exhibit horse behavior similar to that of feral horse herds. Stallions herd, drive, and defend all members of their family, while the mares often display leadership in the family. Stallions and mares stay with their preferred partners for years. While behavioral synchronization is high among mares, stallions other than the main"
"can cause lifelong soundness problems. On the other hand, insufficient nutrition to mare or foal can cause stunted growth and other health problems for the foal as it gets older. It is typical for foals under human management to be weaned between four and six months of age, though under natural conditions, they may nurse for longer, occasionally until the following year when the mare foals again. Some foals can nurse for up to three years in domesticity because the mare is less likely to conceive another foetus. A foal that has been weaned but is less than one year"

Although she has had no top-class runners, she has produced at least three winners: Marling (horse) Marling (foaled 17 March 1989) was an Irish-bred, British-trained Thoroughbred racehorse and broodmare. She was one of the leading European two-year-olds of 1991 when she was unbeaten in four races including the Queen Mary Stakes and Cheveley Park Stakes. In the following year she was narrowly beaten in the 1000 Guineas but went on to win the Irish 1000 Guineas,"
"is stillborn, or is unable to stand & nurse, it is not considered a live foal, and the mare owner is entitled to a re-breeding. If the foal does stand after birth and nurses from the mare, it is considered a live foal, even if it dies soon after. Some contracts are more generous, specifying that the foal must survive for at least 12 or 24 hours after first nursing. If the foal survives this long and then dies, it was still a live foal, and the mare owner is ""not"" entitled to a re-breeding. (But many stallion owners will"
"natal harems. When a mare reaches sexual maturity, she exhibits the estrous posture, which attracts nearby stallions, both bachelors and harem leaders. Her family stallion (likely her father) chases off or fights stallions attempting to abduct her. Even after a young mare is isolated from her natal harem, the fight over her continues until her estrous cycle is over, and it starts again with the next estrous cycle. It is rare that the mare's original abductor keeps her for long. When the mare finally ovulates, the male that impregnates her keeps her for good. Thus, the mare becomes a permanent"

In some cases, particularly informal nomenclature, a gelding under four years is still called a colt. A rig or ridgling is a male equine with a retained testicle or one which has been incompletely castrated. In the wild, colts are driven from their herds by the herd stallion somewhere between the age of one and two. This may be, in part, an instinct to prevent inbreeding. When"

Horses with the same coat color are often named differently depending on the tone of the color. The position of a white spot also creates other names as follows: A stallion reaches suitable breeding age by roughly three to four years old, and a three-year-old mare is in the best breeding condition during the spring. The official breeding period lasts for 25 years. Jeju horses belong to long day breeders, whose mating occurs from March to August"
