Sheep Husbandry - Flock Management Styles

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.
