Lavradeiro
The or Wild Horse of Roraima is a Brazilian breed or population of feral horses of Colonial Spanish type in the state of Roraima, in northern Brazil. The name derives from the or savannah terrain in that region. A conservation herd was established in Amajari by the Empresa Brasileira de Pesquisa Agropecuária, the national organisation for agricultural research, in about 1991. History The Lavradeiro is of Criollo or Colonial Spanish type, descending from Iberian horses brought to the Americas by the Conquistadores Horses of this type were brought into Roraima during the period of Portuguese colonisation in the eighteenth century. The horses were managed extensively on the unfenced savannah or ''lavrado'', and a substantial feral population established itself. The horses became hardy and well-adapted to the difficult climate and poor grazing of the area. Until about 1980 this population numbered some head, but by the end of the decade numbers had fallen to no mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roraima
Roraima (, ) is one of the 26 states of Brazil. Located in the country's North Region, it is the northernmost and most geographically and logistically isolated state in Brazil. It is bordered by the state of Pará to the southeast, Amazonas to the south and west, Venezuela to the north and northwest, and Guyana to the east. The state covers an area of approximately , slightly larger than Belarus, being the fourteenth largest Brazilian state by area. The city of Boa Vista is the capital and largest city in the state, and is the only capital in the country located entirely in the Northern Hemisphere. Antônio Denarium, a member of the conservative Progressistas party, has been the governor of the state since 2019. Roraima is the least populous state in Brazil, with an estimated population of 631,181 inhabitants as of 2020. It is also the state with the lowest population density in Brazil, with 2.01 inhabitants per square kilometre. Its economy, based mainly on the tertia ...

Feral Horse
A feral horse is a free-roaming horse of domesticated stock. As such, a feral horse is not a wild animal in the sense of an animal without domesticated ancestors. However, some populations of feral horses are managed as wildlife, and these horses often are popularly called "wild" horses. Feral horses are descended from domestic horses that strayed, escaped, or were deliberately released into the wild and remained to survive and reproduce there. Away from humans, over time, these animals' patterns of behavior revert to behavior more closely resembling that of wild horses. Some horses that live in a feral state but may be occasionally handled or managed by humans, particularly if privately owned, are referred to as "semi-feral". Feral horses live in groups called a ''herd'', ''band'', ''harem,'' or ''mob''. Feral horse herds, like those of wild horses, are usually made up of small harems led by a dominant mare, containing additional mares, their foals, and immature horses of ...

Equine Infectious Anemia
Equine infectious anemia or equine infectious anaemia (EIA), also known by horsemen as swamp fever, is a horse disease caused by a retrovirus (''Equine infectious anemia virus'') and transmitted by bloodsucking insects. The virus (''EIAV'') is endemic in the Americas, parts of Europe, the Middle and Far East, Russia, and South Africa. The virus is a lentivirus, like human immunodeficiency virus (HIV). Like HIV, EIA can be transmitted through blood, milk, and body secretions. Transmission is primarily through biting flies, such as the horse-fly and deer-fly. The virus survives up to 4 hours in the vector. Contaminated surgical equipment and recycled needles and syringes, and bits can transmit the disease. Mares can transmit the disease to their foals via the placenta. The risk of transmitting the disease is greatest when an infected horse is ill, as the blood levels of the virus are then highest. Stages Acute: The acute form is a sudden onset of the disease at full-force. Sympt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Withers
The withers is the ridge between the shoulder blades of an animal, typically a quadruped. In many species, it is the tallest point of the body. In horses and dogs, it is the standard place to measure the animal's height. In contrast, cattle are often measured to the top of the hips. The term (pronounced ) derives from Old English ''wither'' (“against”), because it is the part of a draft animal that pushes against a load. Horses The withers in horses are formed by the dorsal spinal processes of roughly the 3rd through 11th thoracic vertebrae, which are unusually long in this area. Most horses have 18 thoracic vertebrae. The processes at the withers can be more than long. Since they do not move relative to the ground as the horse's head does, the withers are used as the measuring point for the height of a horse. Horses are sometimes measured in hands – one hand is . Horse heights are extremely variable, from small pony breeds to large draft breeds. The height at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germplasm
Germplasm are living genetic resources such as seeds or tissues that are maintained for the purpose of animal and plant breeding, preservation, and other research uses. These resources may take the form of seed collections stored in seed banks, trees growing in nurseries, animal breeding lines maintained in animal breeding programs or gene banks, etc. Germplasm collections can range from collections of wild species to elite, domesticated breeding lines that have undergone extensive human selection. Germplasm collection is important for the maintenance of biological diversity and food security.

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 do no ...

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. 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 ...

Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use. International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. Also included are species that have gone ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-breeding
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. ''Crossbreeding'', sometimes called "designer crossbreeding", is the process of breeding such an organism, While crossbreeding is used to maintain health and viability of organisms, irresponsible crossbreeding can also produce organisms of inferior quality or dilute a purebred gene pool to the point of extinction of a given breed of organism. A domestic animal of unknown ancestry, where the breed status of only one parent or grandparent is known, may also be called a crossbreed though the term "mixed breed" is technically more accurate. Outcrossing is a type of crossbreeding used within a purebred breed to increase the genetic diversity within the breed, particularly when there is a need to avoid inbreeding. In animal breeding, ''crossbreeds'' are crosses within a single species, while '' hybrids'' are crosses between different species. In plant breeding terminology, the term ' ...

Extensive Farming
Extensive farming or extensive agriculture (as opposed to intensive farming) is an Agriculture production system that uses small inputs of labour, fertilizers, and capital, relative to the land area being farmed. Systems Extensive farming is most commonly means raising sheep and cattle in areas with low agricultural productivity, but includes large-scale growing of wheat, barley, cooking oils and other grain crops in areas like the Murray-Darling Basin in Australia. Here, owing to the extreme age and poverty of the soils, yields per hectare are very low, but the flat terrain and very large farm sizes mean yields per unit of labor are high. Nomadic herding is an extreme example of extensive farming, where herders move their animals to use feed from occasional sunlight. Geography Extensive farming is found in the mid-latitude sections of most continents, well as in desert regions where water for cropping is not available. The nature of extensive farming means it requires less ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
