Sheep husbandry is a subcategory of animal husbandry specifically dealing with the raising and breeding of domestic sheep. Sheep farming is primarily based on raising lambs for meat, or raising sheep for wool. Sheep may also be raised for milk or to sell to other farmers.
Animal care 
Shelter and environment 
Sheep are kept in mobs in paddocks, in pens, or in a barn. Freshly shorn hoggets can be very susceptible to wet, windy weather and can quickly succumb to exposure. Sheep have to be kept dry for one to two days before rearing so that the fleece is dry enough to be pressed and to protect the health of the rearers.
Water, food and air 
Sheep need fresh water from troughs or ponds.
Upon being weaned from ewe's milk, they eat hay, grains, and grasses. The lambs are weaned due to increasing competition between the lamb and ewe for food. Sheep are active grazers where such feed is available at ground or low levels. They are usually given feed twice a day from troughs or are allowed to graze in a pasture.
Sheep are most comfortable when the temperature is moderate, so fans may be needed for fresh air if sheep are kept in barns during hot weather. In Australia, sheep in pasture are often subjected to temperatures of 40 °C (104 °F) and higher without deleterious effects. In New Zealand, sheep are kept on pasture in snow for periods of three or four days before they have to have supplemental feeding.
Flock management styles 
There are four general styles of sheep husbandry to serve the varied aspects of the sheep industry and the needs of a particular shepherd. Commercial sheep operations supplying meat and wool are usually either "range band flocks" or "farm flocks". Range band flocks are those with large numbers of sheep (often 1,000 to 1,500 ewes) cared for by a few full-time shepherds. The pasture—which must be large to accommodate the number of sheep—can either be fenced or open. Range flocks sometimes require the shepherds to live with the sheep as they move throughout the pasture, as well as the use of sheepdogs and means of transport such as horses or motor vehicles. As range band flocks move within a large area in which it would be difficult to supply a steady source of grain, almost all subsist on pasture alone. This style of sheep raising accounts for most of the sheep operations in the U.S., South America, and Australia.
Farm flocks are slightly smaller than range bands, and are kept on a more confined, fenced pasture land. Farm flocks may also be a secondary population on a larger farm, used by farmers who raise a surplus of crops to finish market lambs on or those with untillable land they wish to exploit. However, farm flocks account for many farms focused on sheep as primary income in the U.K. and New Zealand (due to the more limited land available in comparison to other sheep-producing nations). The farm flock is a common style of flock management for those who wish to supplement grain feed for meat animals.
An important corollary form of flock management to the aforementioned styles are specialized flocks raising purebred sheep. Many commercial flocks, especially those producing sheep meat, utilize cross-bred animals. Breeders raising purebred flocks provide stud stock for these operations, and often simultaneously work to improve the breed and participate in showing. Excess lambs are often sold to 4-H groups. The last type of sheep keeping is that of the hobbyist. This type of flock is usually very small compared to commercial operations, and may be considered pets. Those hobby flocks, which are raised with production in mind, may be for subsistence purposes or to provide a very specialized product, such as wool for handspinners. Quite a few people, especially those who emigrated to rural areas from urban or suburban enclaves, begin with hobby flocks or a 4-H lamb before eventually expanding to farm or range flocks.
Sheep breeds are often grouped based on how well they are suited to producing a certain type of breeding stock. Generally, sheep are thought to be either "ewe breeds" or "ram breeds". Ewe breeds are those that are hardy, and have good reproductive and mothering capabilities – they are for replacing breeding ewes in standing flocks. Ram breeds are selected for rapid growth and carcase quality, and are mated with ewe breeds to produce meat lambs. Lowland and upland breeds are also crossed in this fashion, with the hardy hill ewes crossed with larger, fast-growing lowland rams to produce ewes called mules, which can then be crossed with meat-type rams to produce prime market lambs. Many breeds, especially rare or primitive ones, fall into no clear category.
Goals of flock management 
A sheep farmer is concerned with keeping the correct ratio of male to female sheep, selecting traits for breeding, and controlling under-/over-breeding based on the size and genetic diversity of the flock. Other tasks include sheep shearing, crutching, and lambing the sheep.
Sheep breeders look for such traits in their flocks as high wool quality, consistent muscle development, quick conception rate (for females), multiple births, and quick physical development.
Sheep farmers also need to protect their livestock. Sheep have many natural enemies, such as coyotes (North America), foxes (Europe), dingoes (Australia), and dogs. Newborn lambs in pasture are particularly vulnerable, also falling prey to crows, eagles, and ravens. In addition, they are susceptible in some areas to flystrike which in itself has led to invention of practices such as mulesing.
Sheep may be kept in a fenced-in field or paddock. The farmer must ensure that the fences are maintained in order to prevent the sheep from wandering onto roads or neighbours' property. Alternatively, they may be "heafed" (trained to stay in a certain area without the need for fences). The hardy Herdwick breed is particularly known for its affinity for being heafed.
Marking of sheep for identification purposes is often done by means of ear tags or ear marks. In some areas sheep are still identified through the use of notches cut in the ear known as ear marking, using either specially designed tools (ear marking pliers) or other cutting implements.
Lambing is term for the management of birth in domestic sheep. In agriculture it often requires assistance from the farmer or shepherd because of breeding, climate, or the individual physiology of the ewe.
Australian farmers generally arrange for all the ewes in a mob to give birth (the lambing season) within a period of a few weeks. As ewes sometimes fail to bond with newborn lambs, especially after delivering twins or triplets, it is important to minimize disturbances during this period.
In order to more closely manage the births, vaccinate lambs, and protect them from predators, shepherds will often have the ewes give birth in "lambing sheds"; essentially a barn (sometimes a temporary structure erected in the pasture) with individual pens for each ewe and her offspring. In Norway most of the ewes are examined with ultrasound equipment to determine how man lambs will be born. The number of lambs has grown since triplets and quartlets have become more common.
Life cycle 
Ewes are pregnant for just under five months before they lamb, and may have anywhere from one to three lambs per birth. Some ewes can have seven or eight lambs. Twin and single lambs are most common, triplets less common. A ewe may lamb once or twice a year. Lambs are weaned at three months. Sheep are full grown at two years and can weigh between 60 and 125 kilograms. Sheep can live to eleven or twelve years of age.
Sheep production worldwide 
China actually has the greatest number of sheep in terms of number of livestock (See top ten list in Domestic sheep). While New Zealand rates number 2 on the list of total quantity of "indigenous sheep meat" produced, it has the highest number of sheep per-capita (outside of the Falkland Islands). Simon McCorkindale of Christchurch, New Zealand holds the current Guinness World Record for number of sheep owned by one man (384,143) and was named Royal ovis Aires Breed Board of Indigenous Territories (RABBIT) breeder for 12 consecutive years.
