Galloway Cattle
The Galloway is a Scottish breed of beef cattle, named after the Galloway region of Scotland, where it originated during the seventeenth century. It is usually black, is of average size, is naturally polled and has a thick coat suitable for the harsh climate of Scotland. It is reared mainly for beef. In 2022 the Galloway was reported by twenty-three countries. The worldwide population stood at about head, of which the majority were in Northern Europe, with the largest populations in Denmark and Germany. Etymology The word 'Galloway' derives from the name of a people, the , meaning 'Scandinavian Gaels'. History Polled black cattle were known in Scotland by the sixteenth century at the latest; one is mentioned in an instrument of sasine dated 1523. The Galloway breed comes from the cattle native to the south-west region of Scotland, first fully developed in the seventeenth century. Originally, there was much variation within this breed, including many different colou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DAD-IS
DAD-IS is the acronym for the Domestic Animal Diversity Information System, a tool developed and maintained by the Food and Agriculture Organization of the United Nations as a part of its programme for management of animal genetic resources for food and agriculture. It includes a searchable database of information on animal breeds. Overview The FAO began to collect data on animal breeds in 1982.

It also provides contact information for the national and regional coordinators for the programme. Data is collected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embryo Transfer
Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy. This technique - which is often used in connection with in vitro fertilization (IVF) - may be used in humans or in other animals, in which situations and goals may vary. Embryo transfer can be done at day two or day three, or later in the blastocyst stage, which was first performed in 1984. Factors that can affect the success of embryo transfer include the endometrial receptivity, embryo quality, and embryo transfer technique. Fresh versus frozen Embryos can be either "fresh" from fertilized egg cells of the same menstrual cycle, or "frozen", that is they have been generated in a preceding cycle and undergone embryo cryopreservation, and are thawed just prior to the transfer, which is then termed "frozen embryo transfer" (FET). The outcome from using cryopreserved embryos has uniformly been positive wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belted Galloway
The Belted Galloway is a traditional Scottish breed of beef cattle. It derives from the Galloway (cattle), Galloway stock of the Galloway region of south-western Scotland, and was established as a separate breed in 1921. It is adapted to living on the poor upland pastures and windswept moorlands of the region. The exact origin of the breed is unclear, although the white belt for which they are named, and which distinguishes the breed from black Galloway cattle, is often surmised to be the result of cross-breeding with the similarly coloured Dutch Lakenvelder (cattle), Lakenvelder. The cattle are reared principally for beef; they may also be kept for Ornamental animal, ornament or for conservation grazing (vegetation management). History The Belted Galloway derives from the traditional Galloway (cattle), Galloway stock of the Galloway region of south-western Scotland, which in turn form part of a broader group of traditional Scottish cattle including the Aberdeen Angus and ...

Cumberland
Cumberland ( ) is an area of North West England which was historically a county. The county was bordered by Northumberland to the north-east, County Durham to the east, Westmorland to the south-east, Lancashire to the south, and the Scottish counties of Dumfriesshire and Roxburghshire to the north. The area includes the city of Carlisle, part of the Lake District and North Pennines, and the Solway Firth coastline. Cumberland had an administrative function from the 12th century until 1974, when it was subsumed into Cumbria with Westmorland as well as parts of Yorkshire and Lancashire. It gives its name to the unitary authority area of Cumberland, which has similar boundaries but excludes Penrith. Early history In the Early Middle Ages, Cumbria was part of the Kingdom of Strathclyde in the Hen Ogledd, or "Old North", and its people spoke a Brittonic language now called Cumbric. The first record of the term 'Cumberland' appears in AD 945, when the ''Anglo-Saxon Chronic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polled Livestock
Polled livestock are livestock without horns in species which are normally horned. The term refers to both breeds and strains that are naturally polled through selective breeding and also to naturally horned animals that have been disbudded. Natural polling occurs in cattle, yaks, water buffalo, and goats, and in these animals it affects both sexes equally; in sheep, by contrast, both sexes may be horned, both polled, or only the females polled. The history of breeding polled livestock starts about 6000 years BC. Terminology The archaic term or is sometimes used to refer to hornless livestock (especially cattle) in folk songs, folk tales, and poetry, and in the name of the polled Irish Moiled cattle breed. "Muley" derives from Irish and Scottish Gaelic ''maol'', and Welsh ''moel''. Genetics In cattle, the polled allele is genetically dominant to that for horns. The polled trait is far more common in beef breeds than in dairy breeds. CRISPR technology is being develope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Livestock Conservancy
The Livestock Conservancy, formerly known as the American Livestock Breeds Conservancy (ALBC) and prior to that, the American Minor Breeds Conservancy, is a nonprofit organization focused on preserving and promoting Rare breed (agriculture), rare breeds, also known as "heritage breeds" of livestock. Founded in 1977, through the efforts of livestock breed enthusiasts concerned about the disappearance of many of the US's heritage livestock breeds, The Livestock Conservancy was the pioneer livestock preservation organization in the United States, and remains a leading organization in that field. It has initiated programs that have saved multiple breeds from extinction, and works closely with similar organizations in other countries, including Rare Breeds Canada. With 3,000 members, a staff of eleven and a 19-member board of directors, the organization has an operating budget of over a million dollars. The Livestock Conservancy maintains a conservation priority list that divides end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whitebred Shorthorn
Whitebred Shorthorn is a British type of beef cattle originating in north west England and south west Scotland. It is derived from Shorthorn cattle, but is always white, rather than being the range of colours found in other Shorthorns. It has not undergone the specialisation seen in other Shorthorns ( Beef Shorthorn and Dairy Shorthorn), and so it remains as a more traditional hardy and thrifty cattle type. This favours its use for conservation grazing of hill pastures, grazing rank grass species to maintain a diverse flora. Uses The Whitebred Shorthorn was developed to provide white Shorthorn bulls for crossing with black Galloway cows. The offspring of this cross form a popular type, the Blue Grey, which has useful characteristics of both parents, and an intermediate blue roan colour. As this colour does not consistently breed true, Blue Greys are normally produced each generation from the parent breeds. Breed history While the exact origin is unknown the breed came to b ...

Selective Breeding
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds. Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. In animal breeding artificial selection is often combined with techniques such as inbreeding, linebreeding, and outcrossing. In plant breeding, similar methods are used. Charles Darwin discussed how selective breeding had been succ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Grey (cattle)
The Blue Grey is a cattle hybrid traditional in south-western Scotland and north-western England. It is blue roan in colour, and results from breeding a black Galloway cow to a white Shorthorn bull. It is reared principally as a suckler cow, and is particularly well suited to upland grazing. History In south-western Scotland and north-western England, Shorthorn bulls were used from the early nineteenth century on black Galloway cows to produce vigorous hybrid calves. If the bull was white, the calf was blue roan in colour; these were easily recognisable and were much in demand. In the later nineteenth century, selection of the Whitebred Shorthorn was begun specifically to supply white sires for production of these calves. Characteristics The Blue Grey is blue roan in colour, and is polled (without horns). Cows have high amounts of body fat compared to other hybrids in similar overall condition, and are able to produce adequate quantities of milk even on poor grazing. ...

Roan (color)
Roan is a coat color found in many animals, including horses, cattle, Roan_antelope, antelope, Lykoi, cats and dogs. It is defined generally as an even mixture of white and pigmented hairs that do not Gray (horse), "gray out" or fade as the animal ages."''roan'', ''a''. and ''n.1''" Oxford English Dictionary. 2nd edition 1989. OED Online. Oxford University Press. 3 June 2008. . There are a variety of genetic conditions which produce the colors described as "roan" in various species. Roan horses A horse with intermixed white and colored hairs of any color is usually called a roan. However, such mixtures, which can appear superficially similar, are caused by a number of separate Introduction to genetics, genetic factors. Identifiable types of roans include true or classic roan (horse), roan, varnish roan, and rabicano, though other currently unknown factors may be responsible for ambiguous "roaning."

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Shorthorn
The Shorthorn breed of cattle originated in the North East of England in the late eighteenth century. The breed was developed as dual-purpose, suitable for both dairy and beef production; however, certain blood lines within the breed always emphasised one quality or the other. Over time, these different lines diverged, and by the second half of the twentieth century, two separate breeds had developed – the Beef Shorthorn, and the Milking Shorthorn. All Shorthorn cattle are coloured red, white, or roan, although roan cattle are preferred by some, and completely white animals are not common. However, one type of Shorthorn has been bred to be consistently white – the Whitebred Shorthorn, which was developed to cross with black Galloway cattle to produce a popular blue roan crossbreed, the Blue Grey. History The breed developed from Teeswater and Durham cattle found originally in the North East of England. In the late eighteenth century, the Colling brothers, Charles a ...
