Newfoundland sheep

Last updated November 06, 2023

The Newfoundland, also called the Newfoundland Local,^[1] is a breed of sheep native to Newfoundland.

The Islands of Newfoundland are mainly supported through fisheries, but a persistent population of sheep has been present since the sixteenth and seventeenth centuries, and a native landrace has developed since that time. Though it has never been fully recognized as a breed, Newfoundland sheep are a distinct genetic base.^[2] Both Border Cheviot and North Ronaldsay sheep are known to have been major contributors to Newfoundland bloodlines, and there may have also been contributions from other breeds such as the Suffolk, Border Leicester, Portland Sheep and Scottish Blackface.^[1]

Newfoundland sheep show fairly wide variability, but are generally medium sheep - Very few ewes are horned, and rams can be either horned or few are polled. All Newfoundlands are characterized by a great deal of hardiness, able to survive off of poor native forage.^[1] Newfoundland Sheep are medium size and come in multiple colors. Rams are mostly horned and some ewes are horned as well.

Newfoundland Sheep very easy lambing with rarely any complications. Good mothers lambs weight about 6-8 pounds (3-4 kg) at birth.

Preliminary Results

NLS flocks across the province have developed into uniform genetic pools. That is to say there should be uniformity within each of the flocks similar to that of other registered breeds. Despite the fact that NLS are kept as small flocks, Sheep from Fortune Bay, Trinity Bay North and Notre Dame Bay had the smallest amount of genetic variability, i.e. they are more uniform than other flocks studied as a result of these small flocks being kept in isolation for 15 to 50 years. 2. The theory that if the NLS identified are classified as one group then there should be relatively small genetic differences among the flocks. The NLS from different regions have different DNA profiles which is consistent with the differences in their sizes, bone structure, face and fleece colours. There was little physical similarities across the flocks. Sheep in Trinity Bay North showed the highest difference compared with those in other regions, particularly with those in Fortune Bay and Notre Dame Bay. Such differences could be the result of different ancestral breeds, differences in climatic conditions under which these sheep have been kept for decades, There has been little information documented on the Local Newfoundland Sheep. Of the information that is documented, the author has concluded that the Border Cheviot characteristics were the most prominent breed while Blackface Highland and Portland sheep were also present. These sheep have survived through extensive management and natural selection and have been recorded to be continuous breeders, easy lambers, good mothers and late maturing lambs. A breed association is required to set the standards of Local Newfoundland Sheep and a breed registry book needs to be maintained. There has been a decent effort made to collect data on the Local Newfoundland sheep. This data needs to be analyzed by a competent animal geneticist. A breeding program needs to be set up to guide the producers into preserving the Local Newfoundland sheep. The DNA fingerprinting, though not compulsory for breed registration, will be a great asset. There has been 37 farms in which data was collected on 336 animals, there are an additional 6 or 7 farms where the animals have been let go for the summer which need to be revisited when the animals are home from summer pasture. The author found that the NLS sheep are generally white with a white face and orange mottle coloring, and a small head. A percentage (10.4%) of these sheep are black with brown coloring intermixed. Generally, "Local" Newfoundland sheep are small, narrow chested animals with a small body frame and are straight in the back with strong short legs and strong pasterns and black hooves. The late maturing trait was particularly noted in the flock of Richard Wells, Exploits Island. This was also observed in a flock on the Northern Peninsula where sheep and lambs were released on the commons in early May and were prepared for market in late November allowing for approximately 240 days to market. It was also noted that there was little information documented on the productivity of "Local" Newfoundland Sheep. This may be a result of farmers being cautious of providing information to government.

In recognizing that there has been an effort made to find what the physical phenotypic characteristics of the "Local" Newfoundland breed of sheep are (by weighing, measuring and recording of these measurements) it is the author's opinion that there are some similarities and differences in the flock of sheep across the province.

The most noticeable differences are usually tall sheep (76 cm at the shoulders) in certain areas versus short sheep (54 cm at the shoulders) which for the most part made up the greater population. The tall sheep resemble the Border Leicester body shape but not the head or face Breed the short sheep resemble the Welsh Mountain Sheep. There were sheep with clean faces (98%) versus sheep with some wool covering on the face (2%) and over the poll. while wool face may have a resemblance to the Dorset, Portland sheep or other breeds. In the general appearance of the face, the bulk of the animals resemble North Ronaldsay sheep in color and distinct appearance but in a larger size and a Border Cheviot body while there are a minority group with some resemblance to Finn sheep or Romanov mountain or island breeds which would be very new to North America. The similarities observed in the flocks across the island are the high percentage of black sheep and lambs in 10.4% of the flocks. These sheep may be indicative of the black faced Highland sheep breed as referred to in the 1955 Royal Commission Report on Agriculture. There were a percentage of the sheep with horns (80 % of rams, 4% of ewes) and though at the time of data collection there were 13 rams, many of these rams had horns which would resemble the Dorset horn. The overall body

Many people have helped in the collecting of blood samples, including Marg Zillig, Roy MacKenzie (NSDAM), Mike Wallace (US Meat Animal Research Center, Nebraska), Brian Magee (Cornell University, NY). DNA from Red Maasai was kindly provided by Dr. Alan Teale and Dr. Olivier Hanotte, the International Livestock Research Institute, Kenya. DNA samples of some of the Icelandic sheep were kindly provided by Dr. Adsridur Palsdottir, Iceland. Many of the Newfoundland Department of Forest Resources and Agrifoods' staff assisted in data and blood collection and in particular Ben Pungtilan, Morley Hann and Michelle Ralph Spears. Special thanks to the Newfoundland Local Steering Committee which is composed Howard Morry Sr., Howard Morry Jr., Richard Coffey and Dan Harwood. Many sheep breeders across Newfoundland and Canada need to be thanked for without their kind collaboration it would not have been possible to complete this experiment. Financial assistance for this project was provided by the Canada/Newfoundland Green Plan, and Canada/Newfoundland Agricultural Safety Net Program. To date there are less than 100 pure on the Island of Newfoundland

Coinciding with a general decline in sheep populations in the region, Newfoundland sheep of the native type decline to less than 200 individuals at one point. Thanks to attention by universities, rare breed organizations, and farmers, numbers have increased, but the breed is considered critically endangered still.^[2]

The North Ronaldsay or Orkney is a breed of sheep from North Ronaldsay, the northernmost island of Orkney, off the north coast of Scotland. It belongs to the Northern European short-tailed sheep group of breeds, and has evolved without much cross-breeding with modern breeds. It is a smaller sheep than most, with the rams (males) horned and ewes (females) mostly hornless. It was formerly kept primarily for wool, but now the two largest flocks are feral, one on North Ronaldsay and another on the Orkney island of Auskerry. The Rare Breeds Survival Trust lists the breed as a priority on its 2021–2022 watchlist, and they are in danger of extinction, with fewer than 600 registered breeding females in the United Kingdom.

Montadale is the name of a breed of domestic sheep developed in the 1930s by E. H. Mattingly, a Midwestern commercial lamb buyer who had a dream of developing the ideal sheep. He had been told that the best start to that goal would be to bring together the best characteristics of Midwestern mutton-type sheep and the big Western range sheep. The Montadale is considered a dual-purpose breed, raised for both wool and meat.

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 Jacob is a British breed of domestic sheep. It combines two characteristics unusual in sheep: it is piebald—dark-coloured with areas of white wool—and it is often polycerate or multi-horned. It most commonly has four horns. The origin of the breed is not known; broken-coloured polycerate sheep were present in England by the middle of the seventeenth century, and were widespread a century later. A breed society was formed in 1969, and a flock book was published from 1972.

The Hebridean is a breed of small black sheep from Scotland, similar to other members of the Northern European short-tailed sheep group, having a short, triangular tail. They often have two pairs of horns. They were often formerly known as "St Kilda" sheep, although unlike Soay and Boreray sheep they are probably not in fact from the St Kilda archipelago.

The Lonk is a British breed of domestic sheep. It belongs to the group of black-faced hill breeds of northern England, and is found in the hills of the central and southern Pennines of Lancashire and Yorkshire. It is documented from the mid-eighteenth century; a flock book was started in 1905.

The Rough Fell is an upland breed of sheep originating in England. It is common on fell and moorland farms, its distribution embracing a large proportion of South Cumbria, parts of the West Riding of Yorkshire, North Lancashire and, more recently, upland parts of Devon. It is very hardy and, as its name suggests, has proved to be well-suited to endure the hardships of exposed and high moorland and mountains. It is one of the largest mountain breeds in Britain. 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 Shetland is a small, wool-producing breed of sheep originating in the Shetland Isles, Scotland, but is now also kept in many other parts of the world. It is part of the Northern European short-tailed sheep group, and it is closely related to the extinct Scottish Dunface. Shetlands are classified as a landrace or "unimproved" breed. This breed is kept for its very fine wool, for meat, and for conservation grazing.

The Norfolk Horn is one of the British black-faced sheep breeds. It differs from other black-faced breeds, which are mainly found in high-rainfall, upland areas, and from most other modern, lowland British sheep breeds in being lightly built and very hardy. This breed is raised primarily for meat.

<span class="mw-page-title-main">Clun Forest sheep</span> Breed of sheep

The Clun Forest is a breed of domestic sheep originating from the area surrounding the Clun Forest in Shropshire, England. Similar to many of the British breeds of upland sheep, Clun Forest are hardy, adaptable, good foragers, and are long–lived. With sleek heads and wide pelvic structures, Clun Forest ewes lamb easily. The breed has a short to medium–length wool and dark brown faces. They are a multi–purpose animal, kept for meat, wool, and milk. Like other dark faced sheep, Clun produce quality lamb and mutton. However, in contrast to more common meat breeds such as Suffolks, their wool is free of undesirable black fibres and kemp, and is suitable for handspinning. The breed's alert and stylish appearance, together with its reputation for hardiness and fecundity have made it popular with hobby farmers and large commercial flock owners alike. The Official Clun Sheep Breeders Society Show & Sale for males and females is held annually in early September at Ludlow livestock market by McCartneys.

Domestic sheep reproduce sexually much like other mammals, and their reproductive strategy is furthermore very similar to other domestic herd animals. A flock of sheep is generally mated by a single ram, which has either been chosen by a farmer or has established dominance through physical contest with other rams. Most sheep have a breeding season (tupping) in the autumn, though some are able to breed year-round.

Sheep or domestic sheep are a domesticated, ruminant mammal 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.

The Basco-Béarnaise or Vasca Carranzana is a breed of domestic sheep originating in the Basque country. It was developed from Basque and Béarnaise sheep during the 1960s to be a single-purpose milk breed.

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 Border Cheviot, also known as the South Country Cheviot, is a breed of domesticated sheep from the UK. It is native to the Cheviot Hills between Scotland and England. Recognized as early as 1372, the breed is reported to have developed from sheep that swam ashore from shipwrecked Spanish ships that fled northward after the defeat of the Armada. This breed is prized for its wool but bred primarily for meat.

The British Milksheep is a robust, dual-purpose sheep commonly known for its milking characteristics.

The Rideau Arcott is a breed of domestic sheep native to Canada, one of only a few livestock breeds native to the country.

The Scottish Dunface, Old Scottish Short-wool, Scottish Whiteface or Scottish Tanface was a type of sheep from Scotland. It was one of the Northern European short-tailed sheep group, and it was probably similar to the sheep kept throughout the British Isles in the Iron Age. By the mid-nineteenth century it had mostly been displaced by the Scottish Blackface and it became extinct on the mainland of Scotland in the late nineteenth century. However, several local types of Dunface survived on islands around Scotland, giving rise to or contributing to existing breeds including the Shetland, North Ronaldsay, Hebridean and Boreray.

<span class="mw-page-title-main">Polled Dorset</span> American breed of sheep

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.
