Colt (horseracing)
A colt is a male horse, usually below the age of four years. Description 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 up to and including the age of four. The term is derived from Proto-Germanic *''kultaz'' ("lump, bundle, offspring") and is etymologically related to "child." An adult male horse, if left intact, is called either a " stallion" if used for breeding, or a horse (sometimes full horse); if castrated, it is called a gelding. 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 test ...

Male
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example ...

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. "Stallion" is also used to refer to males of other equids, including zebras and donkeys. Herd behavior Contrary to popular myths, many stallions ...

Weanling
A weanling is an animal that has just been weaned. The term is usually used to refer to a type of young horse, a foal that has been weaned, usually between six months and a year. Once it is a year old, the horse is referred to as a yearling. The word is also sometimes used to describe young cattle and pigs, but "weaner" is more common in the United States The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territori .... References *Lyons, John and Jennifer J. Denison. ''Bringing Up Baby.'' Primedia Enthusiast Publications, 2002. .

Oxford English Dictionary
The ''Oxford English Dictionary'' (''OED'') is the first and foundational historical dictionary of the English language, published by Oxford University Press (OUP). It traces the historical development of the English language, providing a comprehensive resource to scholars and academic researchers, as well as describing usage in its many variations throughout the world. Work began on the dictionary in 1857, but it was only in 1884 that it began to be published in unbound fascicles as work continued on the project, under the name of ''A New English Dictionary on Historical Principles; Founded Mainly on the Materials Collected by The Philological Society''. In 1895, the title ''The Oxford English Dictionary'' was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in 10 bound volumes. In 1933, the title ''The Oxford English Dictionary'' fully replaced the former name in all occurrences in its reprinting as 12 volumes with a one- ...

Bachelor Herd
A bachelor herd is a herd of (usually) juvenile male animals who are still sexually immature or 'harem'-forming animals who have been thrown out of their parent groups but not yet formed a new family group. It may also refer to a group of males who are not currently territorial or mating with females. Examples include seals, dolphins, lions, and many herbivores such as deer, horses, and elephants. Bachelor herds are thought to provide useful protection for social animals against more established herd competition or aggressive, dominant males. Males in bachelor herds are sometimes closely related to each other. Some animals, for example New Zealand fur seals, live in a bachelor herd all year except for the mating season, when there is a substantial increase in aggression and competition. In many species, males and females move in separate groups, often coming together at mating time, or to fight for territory or mating partners. In many species it is common for males to leave or be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inbreeding
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. Animals avoid incest only rarely. Inbreeding results in homozygosity, which can increase the chances of offspring being affected by recessive traits. In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce. An individual who inherits such deleterious traits is colloquially referred to as ''inbred''. The avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for outcros ...

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 the body is too high for sperm to survive, an undescended testicle is non-functional. The condition is most often discussed in the horse world, as the health and behavioral issues surrounding adult males with the condition are of concern to owners and handlers of such animals. Dogs In dogs, the toy and miniature breeds are considered more susceptible. The testicles usually descend by the time a puppy is 40 days old. In horses Although the rate that testicles descend varies between individual animals, horses over three years with the condition are generally castrated. Surgery called a cryptorchidectomy is used to remove the retained testicle, but different procedures are used, depending on the location inside the body cavity. An undescended ...

Gelding
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 low ...

Castration
Castration is any action, surgical, chemical, or otherwise, by which an individual loses use of the testicles: the male gonad. Surgical castration is bilateral orchiectomy (excision of both testicles), while chemical castration uses pharmaceutical drugs to deactivate the testes. Castration causes sterilization (preventing the castrated person or animal from reproducing); it also greatly reduces the production of hormones, such as testosterone and estrogen. Surgical castration in animals is often called neutering. The term ''castration'' is sometimes also used to refer to the removal of the ovaries in the female, otherwise known as an oophorectomy, or the removal of internal testes, otherwise known as gonadectomy. The equivalent of castration for female animals is spaying. Estrogen levels drop following oophorectomy, and long-term effects of the reduction of sex hormones are significant throughout the body. Castration of animals is intended to favor a desired developme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etymologically
Etymology ()The New Oxford Dictionary of English (1998) – p. 633 "Etymology /ˌɛtɪˈmɒlədʒi/ the study of the class in words and the way their meanings have changed throughout time". is the study of the history of the form of words and, by extension, the origin and evolution of their semantic meaning across time. It is a subfield of historical linguistics, and draws upon comparative semantics, morphology, semiotics, and phonetics. For languages with a long written history, etymologists make use of texts, and texts about the language, to gather knowledge about how words were used during earlier periods, how they developed in meaning and form, or when and how they entered the language. Etymologists also apply the methods of comparative linguistics to reconstruct information about forms that are too old for any direct information to be available. By analyzing related languages with a technique known as the comparative method, linguists can make inferences about their ...

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] |
Proto-Germanic
Proto-Germanic (abbreviated PGmc; also called Common Germanic) is the reconstructed proto-language of the Germanic branch of the Indo-European languages. Proto-Germanic eventually developed from pre-Proto-Germanic into three Germanic branches during the fifth century BC to fifth century AD: West Germanic, East Germanic and North Germanic, which however remained in contact over a considerable time, especially the Ingvaeonic languages (including English), which arose from West Germanic dialects and remained in continued contact with North Germanic. A defining feature of Proto-Germanic is the completion of the process described by Grimm's law, a set of sound changes that occurred between its status as a dialect of Proto-Indo-European and its gradual divergence into a separate language. As it is probable that the development of this sound shift spanned a considerable time (several centuries), Proto-Germanic cannot adequately be reconstructed as a simple node in a tree mode ...
