Overview

The domestic sheep (Ovis aries) is a woolly ruminant kept worldwide as livestock and one of the earliest animals domesticated for agriculture. Sheep are raised primarily for wool, meat, and milk, and there are hundreds of breeds adapted to different climates and purposes. They are best known for their strong flocking instinct and their fleece.

Habitat & Range

Sheep are farm and rangeland animals found on every inhabited continent. Different breeds suit different environments, from cool, wet uplands to dry rangeland, and some hardy breeds graze rough hill pasture with little shelter. Their distribution is a product of human agriculture rather than a natural range, and management differs widely between extensive and intensive systems.

Diet

Sheep are ruminant grazers that feed mainly on grass and other low-growing forage, cropping vegetation close to the ground. Like other ruminants they ferment plant material in a multi-chambered stomach and chew the cud. On farms, grazing may be supplemented with hay, silage, or feed, particularly in winter or during breeding; specific regimes vary by region and flock.

Behavior

Sheep are highly social and have a strong flocking instinct, staying close together for safety as prey animals. They follow one another readily and can become stressed when isolated. Research has shown sheep can recognise individual faces of other sheep and of humans. Flock movement, vocal contact between ewes and lambs, and following behaviour are central to how sheep are managed.

Human Interaction & Conservation

Sheep farming is one of the oldest and most widespread forms of animal agriculture, supplying wool, meat, milk, and shaping many rural landscapes through grazing. As a domestic species, sheep are not given a wild conservation status; relevant issues are welfare, breed conservation, and grazing management. This page is educational and is not a substitute for qualified husbandry or veterinary advice.

Appearance & Recognition

Sheep are stocky ruminants typically covered in a thick wool fleece, though some breeds grow hair instead. Many breeds are naturally polled (hornless), while others have curling horns, usually most prominent in rams. Faces and legs are often free of wool and may be white, brown, or black depending on breed. Most domestic sheep require shearing because, unlike their wild ancestors, they do not shed their fleece naturally.

Similar Animals

Sheep and goats are closely related domestic ruminants in the family Bovidae and are often compared, but they differ in feeding style, tail carriage, and coat. Sheep are also related to wild sheep such as the mouflon, argali, and bighorn sheep, which are separate species with their own ranges and behaviour.

Frequently Asked Questions — Sheep

Why do sheep flock together?
Sheep are prey animals, and staying in a tight group is a natural anti-predator strategy. The flocking instinct means individuals follow the group and can become stressed when separated, which is why low-stress handling keeps flocks calm and moving together.
Do all sheep need shearing?
Most wool breeds do, because selective breeding has produced fleece that grows continuously rather than shedding. Without shearing, the fleece can become heavy and cause welfare problems. Some hair breeds and primitive breeds shed naturally and need little or no shearing.
Are sheep wild animals?
Domestic sheep are a domesticated species, not wildlife. They descend from wild sheep of Eurasia. Feral populations exist in a few places, but the farm sheep is domestic.
