Updated August 1, 20261 min readCited sources

Sheep are domesticated ruminant mammals, usually referring to *Ovis aries*, kept worldwide for wool, meat, and sometimes milk. They were among the earliest animals domesticated by humans, about 9,000–11,000 years ago.

What it is

Sheep are even-toed ungulates in the family Bovidae and subfamily Caprinae, closely related to goats. Domestic sheep (*Ovis aries*) are ruminants with a multi-chambered stomach, allowing them to digest grasses and other plants.

Why it matters

Sheep have been bred for wool, meat, and milk for millennia, making them a key livestock animal worldwide. In Canada, they contribute to wool and lamb production and support rural land management.

Key details

Domestication likely occurred in the Middle East and Asia, with wild ancestors such as the mouflon. Sheep are found on every inhabited continent, adapted to climates from arctic to tropical, and are herbivores that graze on plants.

In short

  • Sheep are domesticated ruminants (*Ovis aries*) raised for wool, meat, and milk.
  • Domesticated about 9,000–11,000 years ago, likely from wild mouflon.
  • Found worldwide, including in Canadian agriculture for wool and lamb.
  • They are herbivores with a multi-chambered stomach for digesting plants.
Canadian angle

Sheep are part of Canadian agriculture, especially in wool and lamb production, and are also relevant to rural land management and livestock farming across several provinces.
