Sheep's milk in the context of Roquefort

Sheep farming or sheep husbandry is the raising and breeding of domestic sheep. It is a branch of animal husbandry. Sheep are raised principally for their meat (lamb and mutton), milk (sheep's milk), and fiber (wool). They also yield sheepskin and parchment.

Sheep can be raised in a range of temperate climates, including arid zones near the equator and other torrid zones. Farmers build fences, housing, shearing sheds, and other facilities on their property, such as for water, feed, transport, and pest control. Most farms are managed so sheep can graze pastures, sometimes under the control of a shepherd or sheep dog.

Casein (/ˈkeɪsiːn/ KAY-seen; from Latin caseus, 'cheese') is a family of related phosphoproteins (αS1, aS2, β, κ) that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. Sheep and cow milk have a higher casein content than other types of milk with human milk having a particularly low casein content.

Casein does not appear to be essential in mammals. For example, the β-casein gene can be deleted in mice. The resulting mice are healthy and fertile, but the growth of their pups is reduced. Similarly, mice lacking the κ-casein gene are healthy, but they did not suckle their pups and failed to lactate, hence the gene is required for reproductive success.

Pecorino is an Italian hard cheese produced from sheep's milk. The name pecorino derives from pecora, which means 'sheep' in Italian.

Feta (/ˈfɛtə/ FET-ə; Greek: φέτα [ˈfeta]) is a Greek brined white cheese made from sheep's milk or from a mixture of sheep and goat's milk. It is soft, with small or no holes, and no skin. Crumbly with a slightly grainy texture, it is formed into large blocks and aged in brine. Its flavor is tangy and salty, ranging from mild to sharp. Feta is used in salads, such as Greek salad, and in pastries, notably the phyllo-based Greek dishes spanakopita 'spinach pie', and tyropita 'cheese pie'. It is often served with olive oil or olives, and sprinkled with aromatic herbs such as oregano. It can also be served cooked (often grilled), as part of a sandwich, in omelettes, and many other dishes.

Since 2002, feta has been a protected designation of origin in the European Union (EU). EU legislation and similar legislation in 25 other countries limits the name feta to cheeses produced in the traditional way in mainland Greece and Lesbos Prefecture, which are made from sheep milk, or from a mixture of sheep milk and up to 30% of goat milk from the same area.
