Shelter and Environment
Sheep are kept in flocks — in pens, in a barn or on pasture. In cold climates sheep need shelter in the winter[citation needed]. Sheep need shelter from rain for a day before shearing so that the fleece is dry enough to be pressed.
Health Care
Sheep, particularly those kept inside, are vaccinated when they are newborn lambs. The lambs receive their first antibodies via their mother's colostrum in the first few hours of life, and then via a vaccination booster every six weeks for next three months and then by booster every six months. Farmers work with animal nutritionists and veterinarians to keep sheep healthy and to manage animal health problems. Lambs may be castrated and have their tails docked for easier shearing, cleanliness and to help protect them from fly strike. Shearers or farmers need to remove wool from the hindquarters, around the a**s, so that droppings do not adhere. In the southern hemisphere this is called dagging or crutching.
Water, Food and Air
Sheep need fresh water from troughs or ponds, except that in some countries, such as New Zealand, there is enough moisture in the grass to satisfy them much of the time.
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[citation needed]. 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 they 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 40 °C (104 °F), and higher, daytime temperatures without deleterious effects. In New Zealand sheep are kept on pasture in snow for periods of 3 or 4 days before they have to have supplemental feeding.
Flock management styles
Generally speaking, 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[citation needed].. The pasture-which must be of large acreage to accommodate the greater number of sheep-can either be fenced or open. Range flocks usually require the shepherds to live with the sheep as they move throughout the pasture[citation needed], 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[citation needed].
Farm flocks are those that are slightly smaller than range bands, and are kept on a more confined, fenced pasture land. Farm flocks may also be a secondary priority on a larger farm, such as 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 to 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[citation needed].
