Rideau Arcott
The Rideau Arcott is a breed of domestic sheep native to Canada, one of only a few livestock breeds native to the country. History The Rideau Arcott was produced from a breeding program that was created in 1966 by Agriculture Canada’s Animal Research Centre in Ottawa; other breeds that were produced from the same program include the Canadian Arcott and the Outaouais Arcott. The goal when creating the Rideau Arcott was to create a breed of sheep that produced multiple offspring rapidly. They introduced new technologies in quantitative genetics, reproductive physiology, nutrition and housing that allowed them to select for the traits they wanted to be expressed in the breed. The research flock was closed in 1974, and the breed was distributed to shepherds beginning in 1988. The Rideau name is a common one in Ottawa. The latter half of its name is an acronym for the Animal Research Centre in Ottawa. One of only a few livestock breeds developed in Canada, the Rideau is a synthes ...

Domestic Sheep
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order (biology), order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and sheep milk, milk. A sheep's wool is the most widely used animal fiber, and is usually harvest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Border Leicester Sheep
The Border Leicester is a British breed of sheep. It is a polled, long-wool sheep and is considered a dual-purpose breed as it is reared both for meat and for wool. The sheep are large but docile. They have been exported to other sheep-producing regions, including Australia and the United States. Description The live weight of a mature Border Leicester ram is in the range of and a mature ewe . A yearling ewe is around . Their white wool tends to be very long and by Merino standards, broad crimped, and in fineness about 32 to 38 microns, and is used for medium- to heavy-weight garments. This wool, though, is prized by spinners because of the crimp and lustre. The sheep are normally shorn twice a year when the wool has reached a length of around . Lambs yield an average of of wool; yearlings may yield at each shearing. The United States, Australian and New Zealand Border Leicesters very rarely sport the extreme of British flocks. All strains of Border Leicesters are known fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Twin
Twins are two offspring produced by the same pregnancy.MedicineNet > Definition of TwinLast Editorial Review: 19 June 2000 Twins can be either ''monozygotic'' ('identical'), meaning that they develop from one zygote, which splits and forms two embryos, or ''dizygotic'' ('non-identical' or 'fraternal'), meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell. Since identical twins develop from one zygote, they will share the same sex, while fraternal twins may or may not. In rare cases twins can have the same mother and different fathers (heteropaternal superfecundation). In contrast, a fetus that develops alone in the womb (the much more common case, in humans) is called a ''singleton'', and the general term for one offspring of a multiple birth is a ''multiple''. Unrelated look-alikes whose resemblance parallels that of twins are referred to as doppelgängers. Statistics The human twin birth rate in the United States rose 76% from ...

Crossbreed
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 ...

Corriedale
The Corriedale is a New Zealand breed of sheep. It was bred from about 1882 in the South Island by James Little, who cross-bred Merino and Lincoln Longwool sheep. The breed was officially recognised in 1911. It has been exported to Australia and to many countries in Africa, Asia, Europe and North and South America. In 2021 it was reported from twenty-five countries, and the total population was estimated at just over 5 million. History The Corriedale was developed in the latter part of the nineteenth century by cross-breeding Merino and Lincoln Longwool sheep, with the aim of producing sheep with grazing requirements intermediate between the lush lowlands which suited the British breeds and the sparse dry grazing preferred by the Merino. The first to attempt this was James Little, who had come to New Zealand from the United Kingdom in 1863, and had previously tried to cross-breed Merinos with British Romney stock. At the Corriedale estate in North Otago, where he was mana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Country Cheviot

Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated s ... raised mainly for meat production. Originated from Scotland. History In 1791, Sir John Sinclair brought ewes from the Cheviot Hills near the English border to the counties of Caithness and Sutherland in north Scotland. He named these sheep "Cheviots" after the hill area they originated. Another hill breed was introduced into the ranges of central Scotland thus the Scottish Blackface created a definite separation between northern counties of Caithness and Sutherland and the border region in southern Scotland. Most authorities speculate that both English and Border Leicesters may have been introduced into the North Country Cheviots at this time. The result was a larger sheep that had a ...

Dorset Horn
The Dorset Horn is an endangered British breed of domestic sheep. It is documented from the seventeenth century, and is highly prolific, sometimes producing two lambing seasons per year. Among British sheep, it is the only breed capable of breeding throughout the winter. History The Dorset Horn originated in Dorset in south-west England. Like the extinct Pink-nosed Somerset to which it is related, it probably derived from cross-breeding of Merinos imported from Spain with local tan-faced sheep similar to the modern Portland. Unlike many British lowland breeds, Dorset sheep were not influenced by cross-breeding with the Leicester or Southdown breeds which were much used for this purpose in the latter eighteenth and early nineteenth centuries. A breeders' society, the Dorset Horn Sheep Breeders' Association, was set up in 1891 and the first flock book was published in the following year. The Dorset Horn was exported to many countries, among them Australia, South Afric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Arcott
The Canadian Arcott is a breed of domestic sheep native to Canada. The latter half of its name is an acronym for the Animal Research Centre in Ottawa, where it was developed along with the Rideau Arcott and the Outaouais Arcott. This breed was a result of a crossbreeding program of Suffolk (37%), Ile de France (28%), Leicester (14%), North Country Cheviot (7%) and Romnelet (6%); the remaining 8% was contributed from Shropshire, Lincoln, Southdown Dorset, East Friesian, Finnsheep and Corriedale. This breed was developed to exhibit strong meat characteristics. Mature individuals are medium-sized as well as short and thick. These animals are able to adapt to pasture or confinement systems with ease. Physical characteristics Canadian Arcotts have white or mottled faces that are free of winkles and wool. This breed is described as having a soft and lustrous fleece of medium grade. They have heavily muscled legs and a long narrow tail that is covered with wool. Mature rams typica ...

Shropshire Sheep
The Shropshire breed of domestic sheep originated from the hills of Shropshire, and North Staffordshire, England, during the 1840s. The breeders in the area used the local horned black-faced sheep and crossed them with a few breeds of white-faced sheep ( Southdown, Cotswold, and Leicester). This produced a medium-sized polled (hornless) sheep that produced good wool and meat. In 1855 the first Shropshires were imported into the United States (Virginia). This breed is raised primarily for meat. 1800s In 1859 the breed was officially recognized by the Royal Agricultural Society as being a distinct breed. The popularity of the Shropshire breed grew rapidly in England, and in 1882 Shropshire breeders founded the Shropshire Sheep Breeders' Association and Flock Book Society, the world's first such society for sheep. The same year the Society published the first Flock Book, a record of sheep bred and their breeders. The Society still survives, and still publishes a Flock Book ann ...

East Friesian Sheep
The East Friesian is a breed of dairy sheep originating from East Frisia in northern Germany. It is one of the best milk sheep in terms of yield per ewe. Breeds of sheep for commercial milk production', published by Cooperative Extension of the University of Wisconsin-Extension, 2004. The Agricultural Cooperative Extension of the University of Wisconsin has a few other related publications online under the headin History The breed originated from the Friesland area in northern Germany and Holland. In Europe the breed's main purpose is to produce milk. It is also used as a cross for other breeds to improve milk production in non-dairy breeds of sheep. In 1992 eleven pregnant ewes and four rams were imported into New Zealand from Sweden. The sheep were placed in quarantine in Silverstream. A breeding program was created that used embryo transfer techniques. Only embryos from these original sheep were allowed to be released from the quarantine. In March 1996 the first sheep were r ...
