Domestic sheep in the context of "Artiodactyla"

Animal fibers or animal fibres (see spelling differences) are natural fibers that consist largely of certain proteins. Examples include silk, hair/fur (including wool) and feathers. The animal fibers used most commonly both in the manufacturing world as well as by the hand spinners are wool from domestic sheep and silk. Also very popular are alpaca fiber and mohair from Angora goats. Unusual fibers such as Angora wool from rabbits and Chiengora from dogs also exist, but are rarely used for mass production.

Not all animal fibers have the same properties, and even within a species the fiber is not consistent. Merino is a very soft, fine wool, while Cotswold is coarser, and yet both Merino and Cotswold are types of sheep. This comparison can be continued on the microscopic level, comparing the diameter and structure of the fiber. With animal fibers, and natural fibers in general, the individual fibers look different, whereas all synthetic fibers look the same. This provides an easy way to differentiate between natural and synthetic fibers under a microscope.

A haruspex was a person trained to practise divination by the inspection of the entrails of sacrificed animals, especially the livers of sacrificed sheep and poultry, a practice called haruspicy in the ancient Rome.Various ancient cultures of the Near East, such as the Babylonians, also read omens specifically from the liver, a practice also known by the Greek term hepatoscopy (also hepatomancy).

The Lincoln Longwool is an old British breed of sheep. It is the largest sheep of the United Kingdom, and was bred specifically for wool production. The fleece is coarse, wavy, lustrous and long, and hangs in broad staples that separate easily. The heaviest fleece on record was from a Lincoln ram.

Many were exported to other countries, particularly in the twentieth century, and the Lincoln has influenced sheep husbandry in many parts of the world, often through cross-breeding with Merino stock.

Ovis is a genus of mammals, part of the Caprinae subfamily of the ruminant family Bovidae. Its seven species are highly sociable, and are known as sheep or ovines. Domestic sheep are members of the genus, and are thought to be descended from the wild mouflon of central and southwest Asia.

Lanolin (from Latin lāna 'wool', and oleum 'oil'), also called wool fat, wool yolk, wool wax, sheep grease, sheep yolk, or wool grease, is a wax secreted by the sebaceous glands of wool-bearing animals. Lanolin used by humans comes from domestic sheep breeds that are raised specifically for their wool. Historically, many pharmacopoeias have referred to lanolin as wool fat (adeps lanae); however, as lanolin lacks glycerides (glycerol esters), it is not a true fat. Lanolin primarily consists of sterol esters instead. Lanolin's waterproofing property aids sheep in shedding water from their coats. Certain breeds of sheep produce large amounts of lanolin.

Lanolin in nature protects wool and skin from climate and the environment; it is also involved in skin (integumental) hygiene. Lanolin and its derivatives are used in the protection, treatment, and beautification of human skin.

The Merino is a breed or group of breeds of domestic sheep, characterised by very fine soft wool. It was established in the Iberian Peninsula (modern Spain and Portugal) near the end of the Middle Ages, and was for several centuries kept as a strict Spanish monopoly; exports of the breed were not allowed, and those who tried risked capital punishment. During the eighteenth century, flocks were sent to the courts of a number of European countries, including France (where they developed into the Rambouillet), Hungary, the Netherlands, Prussia, Saxony and Sweden.

The Merino subsequently spread to many parts of the world, including South Africa, Australia, and New Zealand. Numerous recognised breeds, strains and variants have developed from the original type; these include, among others, the American Merino and Delaine Merino in the Americas, the Australian Merino, Booroola Merino and Peppin Merino in Oceania, and the Gentile di Puglia, Merinolandschaf and Rambouillet in Europe.

The Cotswold is a British breed of domestic sheep. It originates in, and is named for, the Cotswold hills of the southern midlands of England. It is a large long-woollen sheep, and is kept as a dual-purpose breed, providing both meat and wool.

It is a rare breed: in 2021 it was listed as "at risk" on the watchlist of the Rare Breeds Survival Trust.

Sheepskin is the hide of a sheep, sometimes also called lambskin. Unlike common leather, sheepskin is tanned with the fleece intact, as in a pelt.

The guinea (/ˈɡɪniː/; commonly abbreviated gn., or gns. in plural) was a coin, minted in Great Britain between 1663 and 1814, that contained approximately one-quarter of an ounce of gold. The name came from the Guinea region in West Africa, from where much of the gold used to make the coins was sourced. It was the first English machine-struck gold coin, originally representing a value of 20 shillings in sterling specie, equal to one pound, but rises in the price of gold relative to silver caused the value of the guinea to increase, at times to as high as thirty shillings. From 1717 to 1816, its value was officially fixed at twenty-one shillings, (one pound and one shilling, £1.05). At 2023 prices, the purchasing power of an 1815 guinea was about £98.

In the Great Recoinage of 1816, the guinea was demonetised and replaced by the gold sovereign. Following the Great Recoinage, the word "guinea" was retained as a colloquial or specialised term, even though the coins were no longer in use; the term guinea also survived as a unit of account in some fields. Notable usages included professional fees (medical, legal, etc.), which were often invoiced in guineas, and horse racing and greyhound racing, and the sale of rams.
