Gromark (sheep)
Gromark sheep are a large-framed, plain bodied dual-purpose ( meat and wool) breed of sheep that were under development in 1965 by Arthur C. Godlee at "Marengo", Tamworth, New South Wales. They were selected for a high growth rate, fertility, wool quality and carcase attributes. Characteristics The Gromark is a prime sheep fixed at approximately 69 percent Corriedale and 50 percent Border Leicester genetics. It is polled (does not have horns), has a white open face, clean legs.

Lamb And Mutton
Lamb, hogget, and mutton, generically sheep meat, are the meat of domestic sheep, ''Ovis aries''. A sheep in its first year is a lamb and its meat is also lamb. The meat from sheep in their second year is hogget. Older sheep meat is mutton. Generally, "hogget" and "sheep meat" are not used by consumers outside Norway, New Zealand, South Africa, Scotland and Australia. Hogget has become more common in England, particularly in the North (Lancashire and Yorkshire) often in association with rare breed and organic farming. In South Asian and Caribbean cuisine, "mutton" often means goat meat.''Oxford English Dictionary'', 3rd edition, June 2003''s.v.'',_definition_1b_At_various_times_and_places,_"mutton"_or_"goat_mutton"_has_occasionally_been_used_to_mean_goat_meat.

Wool
Wool is the textile fibre obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but lack c ...

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 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 milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tamworth, New South Wales
Tamworth is a city and administrative centre of the north-western region of New South Wales, Australia. Situated on the Peel River (New South Wales), Peel River within the local government area of the Tamworth Regional Council, it is the largest and most populated city in the region, with a population of 63,920 in 2021, making it the second largest inland city in New South Wales. Tamworth is from the Queensland border and is located almost midway between Brisbane and Sydney. The city is known as the "First Town of Lights", being the first place in Australia to use electric street lights in 1888. Tamworth is also famous as the "Country Music Capital of Australia", annually hosting the Tamworth Country Music Festival in late January; the second-biggest country music festival in the world after Nashville. The city is recognised as the National Equine Capital of Australia because of the high number of equine events held in the city and the construction of the world-class Australian ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Border Leicester
The Border Leicester is a British breed of domestic sheep, sheep. It is a Polled livestock, 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 Crimp (wool), crimped, and in fineness about 32 to 38 Wool measurement, 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 ...

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 developed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wool Measurement
A micron (micrometre) is the measurement used to express the diameter of wool fibre. Fine wool fibers have a low micron value. Fibre diameter is the most important characteristic of wool in determining its value. Every fleece comprises a very wide range of fibre diameters—for example a typical Merino fleece will contain fibres of as low as 10 microns in diameter, and there could be fibres with diameters exceeding 25 microns, depending on the age and health (or nutrition) of the sheep. What is usually referred to as wool's "micron" is the mean of the fibre diameters or average diameter. This may be measured in a number of different ways. Small samples can be taken from the side or fleece of a sheep and measured using a portable instrument such as an OFDA2000 (Optical Fibre Diameter Analyser); or a mobile instrument system called a Fleecescan. Both these systems have been studied extensively and if used correctly, they should give reasonably reliable results. Pre wool classing m ...

Dystocia
Obstructed labour, also known as labour dystocia, is the baby not exiting the pelvis because it is physically block during childbirth although the uterus contracts normally. Complications for the baby include not getting enough oxygen which may result in death. It increases the risk of the mother getting an infection, having uterine rupture, or having post-partum bleeding. Long-term complications for the mother include obstetrical fistula. Obstructed labour is said to result in prolonged labour, when the active phase of labour is longer than 12 hours. The main causes of obstructed labour include a large or abnormally positioned baby, a small pelvis, and problems with the birth canal. Abnormal positioning includes shoulder dystocia where the anterior shoulder does not pass easily below the pubic bone. Risk factors for a small pelvis include malnutrition and a lack of exposure to sunlight causing vitamin D deficiency. It is also more common in adolescence as the pelvis may not ha ...

Animal Breeding
Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has revolutionized livestock production throughout the entire world. The scientific theory of animal breeding incorporates population genetics, quantitative genetics, statistics, and recently molecular genetics and is based on the pioneering work of Sewall Wright, Jay Lush, and Charles Roy Henderson, Charles Henderson. Breeding stock Breeding stock is a group of animals used for the purpose of planned breeding. When individuals are looking to breed animals, they look for certain valuable traits in purebred animals, or may intend to use some type of crossbreeding to produce a new type of stock with different, and presumably super abilities in a given area ...
