Sheep farming

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.

Farmers can select from various breeds suitable for their region and market conditions. When the farmer sees that a ewe (female adult) is showing signs of heat or estrus, they can organise for mating with males. Newborn lambs are typically subjected to lamb marking, which involves tail docking, mulesing, earmarking, and males may be castrated.

According to the FAOSTAT database of the United Nations Food and Agriculture Organization, the top five countries by number of head of sheep (average from 1993 to 2013) were: mainland China (146.5 million head), Australia (101.1 million), India (62.1 million), Iran (51.7 million), and the former Sudan (46.2 million). Approximately 540 million sheep are slaughtered each year for meat worldwide.

In 2013, the five countries with the largest number of head of sheep were mainland China (175 million), Australia (75.5 million), India (53.8 million), the former Sudan (52.5 million), and Iran (50.2 million). In 2018, Mongolia had 30.2 million sheep. In 2013, the number of head of sheep were distributed as follows: 44% in Asia, 28.2% in Africa; 11.2% in Europe, 9.1% in Oceania, 7.4% in the Americas.

The top producers of sheep meat (average from 1993 to 2013) were as follows: mainland China (1.6 million); Australia (618,000), New Zealand (519,000), the United Kingdom (335,000), and Turkey (288,857). The top five producers of sheep meat in 2013 were mainland China (2 million), Australia (660,000), New Zealand (450,000), the former Sudan (325,000), and Turkey (295,000).

In the United States, inventory data on sheep began in 1867, when 45 million head of sheep were counted in the United States. The numbers of sheep peaked in 1884 at 51 million head, and then declined over time to almost 6 million head.

Between the 1960s and 2012, per capita per year consumption of lamb and mutton has declined from nearly five pounds (about 2 kg) to just about one pound (450g), because of competition from poultry, pork, beef, and other meats. Between the 1990s and 2012, U.S. sheep operations declined from around 105,000 to around 80,000 because of shrinking revenues and low rates of return. According to the Economic Research Service of the United States Department of Agriculture, the sheep industry accounts for less than one percent of U.S. livestock industry receipts.
