Sheep (pl.: sheep) or domestic sheep (Ovis aries) 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. There are around 1.2 billion domestic sheep as of 2019, making them easily the most common species of sheep. An adult female is referred to as a ewe ( yoo); an intact male as a ram, occasionally a tup; a castrated male as a wether; and a young sheep as a lamb. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget, or mutton), and sheep milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. Ovine meat is called lamb and mutton, with lamb describing meat from younger animals and mutton meat from older ones. Sheep continue to be important for wool and meat today, and are also occasionally raised for pelts, as dairy animals, or as model organisms for science. Sheep husbandry is done throughout the majority of the inhabited world. It was central to agriculture and textiles throughout Eurasia for millennia. In the 21st century, Australia, New Zealand, nations of southern and western South America, South Africa, and the British Isles are most closely associated with sheep production. More recently, China and India host among the largest flocks by absolute count, if as a smaller proportion of their economy. There is a large lexicon of unique terms for sheep husbandry which vary considerably by region and dialect. Use of the word sheep began in Middle English as a derivation of the Old English word scēap. A group of sheep is called a flock. Many other specific terms for the various life stages of sheep exist, generally related to lambing, shearing, and age. As a key animal in the history of farming, sheep have an entrenched place in human culture. Sheep terminology and idiom are common in language and symbolism. As livestock, sheep are most often associated with pastoral, Arcadian imagery. Sheep figure in many mythologies—such as the Golden Fleece—and major religions, especially the Abrahamic traditions. In both ancient and modern religious ritual, sheep are used as sacrificial animals.
