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.
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. The long white wool fleece weighs 4-7 kilos, is about 130 mm long and averages about 30 microns [1] in fibre diameter. [2]
Rams average 100 kg, ewes are approximately 75-80 kg (175lb). The rams are typically used as terminal sires for first-cross fat lamb production, but the ewes do produce large lean lambs. [2] The Gromark breed is hardy with a low incidence of fly strike and dystocia.
Since 1965 Gromark sheep have been selected by objective measurement for good growth, without excessive fat. The results are being used to provide breed-specific parameters to improve the accuracy of Estimated Breeding Values (EBV) produced by Australia's national performance testing scheme for meat sheep. [3] In 1979 the Australian Gromark Breed Society was formed and is committed to performance recording of the breed. [4]
This breed is mostly found in the high rainfall areas of south-east Australia, in New South Wales and Victoria. [2] The Rare Breeds Trust of Australia has classified the breed as "recommended for investigation" into its stability as a breeding population. [5]
Sheep farming or sheep husbandry is the raising and breeding of domestic sheep. It is a branch of animal husbandry. Sheep are raised principally for their meat, milk, and fiber (wool). They also yield sheepskin and parchment.
The Drysdale is a New Zealand breed of sheep. It was developed from 1931 by Francis Dry, and derives from sheep of the New Zealand Romney breed in which a mutation caused the the coat to be particularly hairy, and thus suitable for carpet-making. It is a specialised carpet wool breed, but also a useful meat breed.
The Perendale is a breed of sheep developed in New Zealand by Massey Agricultural College for use in steep hill situations. The breed is named after Sir Geoffrey Peren, and it achieves its aims by being the offspring of Romney ewes and Cheviot rams with sturdy legs. It is raised primarily for meat.
Polwarth is a breed of sheep that was developed in Victoria (Australia) during 1880. They were of one-quarter Lincoln and three-quarters Merino bloodlines. They are large, predominantly polled sheep with long, soft, quite fine wool and produce good meat carcasses. They were developed in an attempt to extend the grazing territory of sheep because the Merino was found lacking in hardiness in this respect. A dual-purpose breed with a major emphasis on wool production. Richard Dennis, of Tarndwarncoort in south west Victoria, bred the Polwarth, first known as Dennis Comebacks. Descendants of Richards Dennis continue to grow Polwarth wool at Tarndwarncoort, maintaining the original bloodlines in a flock referred to as the "Blue Dots".
The Lincoln, sometimes called the Lincoln Longwool, is a breed of sheep from England. The Lincoln is the largest British sheep, developed specifically to produce the heaviest, longest and most lustrous fleece of any breed in the world. Great numbers were exported to many countries to improve the size and wool quality of their native breeds. The versatile fleece is in great demand for spinning, weaving and many other crafts.
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.
The Hampshire or Hampshire Down is a breed of sheep which originated around 1829 from a cross of Southdowns with the Old Hampshire breed, the Wiltshire Horn, and the Berkshire Nott, all horned, white-faced sheep — these were native to the open, untilled, hilly stretch of land known as the Hampshire Downs. The Hampshire Down is the worlds leading terminal sire breed.
The Ryeland is one of the oldest English sheep breeds going back seven centuries when the monks of Leominster in Herefordshire bred sheep and grazed them on the rye pastures, giving them their name. It was introduced into Australia in 1919 and are classified as an endangered breed by the Rare Breeds Trust of Australia and also are one of the nine heritage breeds that were the foundation of the sheep and wool industry in Australia. The Ryeland was one of the breeds used to introduce the poll gene to the Dorset breed in the development of the Poll Dorset. This breed is raised primarily for meat.
The Romney, formerly called the Romney Marsh sheep but generally referred to by the local farmers as the Kent, is a breed of sheep originating in England. The Romney is a "long-wool" breed recognized in England by 1800. Exported to other continents, the Romney is an economically important sheep breed, especially to the sheep-meat and wool export trades of New Zealand.
The Texel is a breed of domestic sheep originally from the island of Texel in the Netherlands. A heavily muscled sheep, it produces a lean meat carcass and will pass on this quality to crossbred progeny. The wool is around 32 micrometres and is mostly used for hosiery yarns and knitting wools. It is presently a popular lean meat sheep across Europe, as well as Australia, New Zealand and the United States.
The St Croix is a breed of domestic sheep native to the U.S. Virgin Islands and named for the island of Saint Croix. They are often also called Virgin Island White because those that were imported into North America were selected for white coloration. On the Island of St. Croix, they come in shades of brown, white and black.
The Charollais is a breed of domestic sheep originating in east central France, in the same region in which Charolais cattle originated, Charolles and Saône-et-Loire. It is known for ease of lambing and is used as a terminal sire to increase muscling and growth rate of the lambs. It has been exported internationally, and is commonly used in the United Kingdom as a sire to produce market lambs from pure-bred ewes and mules.
The Kerry Hill is a breed of domestic sheep originating in the county of Powys in Wales. It derives its name from the village of Kerry (Ceri), near Newtown. Kerry Hill sheep have a distinctive and unique coloration, with a white face bearing black markings around the mouth, ears, and eyes. Both rams and ewes are polled. Their wool is white, and their legs are white with black markings. First mentions of the breed date back to the early 19th century, and today it is distributed throughout the United Kingdom, Ireland, the Netherlands, Germany and Denmark. Though still not very numerous, the breed was removed from the records of the Rare Breeds Survival Trust watchlist in 2006. This breed is primarily raised for meat.
The Llanwenog is a breed of domestic sheep originating in Wales. It was developed in the 19th century from the Llanllwni, the Shropshire, Welsh Mountain, and Clun Forest breeds. The Llanwenog's native locale is the Teifi Valley, in western Wales, but it has since spread into other areas. The breed association was formed in 1957. Llanwenogs have black faces and medium-length wool. They have a docile temperament and are known for their profligacy in lambing. The breed has a very placid temperament, is easily handled, easily contained and is well suited to stress free inwintering if necessary. This has important consequences for the health of both the animal and its keeper. This breed is raised primarily for meat.
The Devon Closewool is a British breed of domestic sheep. It is distributed almost exclusively on Exmoor in North Devon, in south-west England. It is raised primarily for meat.
The Comeback is a type of domestic sheep originating in Australia. This type of sheep results from crossbreds produced by British Longwool sheep and Merinos being mated back to Merinos. This cross is made to achieve a finer, better style of wool. Comeback style wool is also produced by Bond, Cormo and Polwarth sheep and they may prove easier to breed than Comebacks. The Comeback sheep are raised for meat and their fine wool.
The Meatmaster is a breed of domestic sheep native to South Africa. Bred in the early 1990s from various hair sheep breeds, the Meatmaster was created with the goal of improving the meat characteristics of African fat-tailed sheep breeds. The fat-tailed sheep had various advantageous characteristics such as hardiness and suitability for desert life, but was slow to mature, had a poor distribution of fat and lacked the muscling of the hind quarters of European breeds. The composite breed increased the amount of muscle and had a better distribution of fat but retained the hair coat and other desirable traits such as resistance to tick-borne diseases and a good flocking instinct.
Aussiedown sheep are an Australian breed of sheep that was developed in the early 1990s using Southdown and Texel genetics. The resulting progeny have a maximum of 75% Southdown and Texel ancestry. They are mainly used as prime lamb sires, by crossing them over purebred or crossbred ewes.
The Eliottdale is a breed of domestic sheep originating from Tasmania. It is a carpet wool breed raised primarily for its wool. Due to the amount of wool grown by the Eliottdale, it needs to be shorn twice per year.
The Polled Dorset is an American breed of domestic sheep. It is a polled (hornless) variant of the British Dorset Horn. It was developed at the North Carolina State University Small Ruminant Unit in the 1950s after a genetic mutation led to the birth of a polled ram. After some years of breeding work, a true-breeding polled strain was established.
