Dorset

The Dorset is a medium-sized sheep bred in the south of England for both meat and wool. British smallholders and commercial flock owners alike keep the breed, since it suits a small holding just as readily as a larger lowland enterprise. Mature animals carry a clean white fleece over a broad, well-fleshed frame, and their placid manner means handling rarely causes trouble at the gate or in the pen.

What sets the Dorset apart from most British breeds is its capacity to breed outside the usual autumn cycle. Where the majority of UK flocks tup in a fixed autumn window and lamb the following spring, Dorset ewes will often come into season across much of the calendar year. A flock manager can therefore plan lambing for autumn or winter as well as spring, supplying the early lamb trade when few other breeds have anything ready.

Two distinct forms exist within the breed. The Horned Dorset carries curled horns on rams and ewes alike, whilst the Polled Dorset has been bred hornless. Beyond the horns, both forms share the same white face, white legs and dense fleece, and both are recognised by the Dorset Horn and Poll Dorset Sheep Breeders' Association, the breed's society in Britain.

Who the breed suits

The Dorset suits keepers after lambs outside the standard spring window, or those running an accelerated lambing system. Its quiet temperament makes it a sensible option for shepherds new to sheep, and its medium frame is easy to manage on a modest acreage. Producers wanting one breed to cover both a meat enterprise and a usable wool clip also find it a practical fit.

The Dorset takes its name from the county in south-west England where the breed was established, with neighbouring Somerset also playing a part in its early development. Sheep of this regional type appear in farming records going back several centuries, kept by farmers who valued ewes able to lamb early and produce enough milk to rear a strong lamb crop. The earliest animals carried horns in both sexes.

The Horned Dorset became the recognised form of the breed, and breeders kept it going for its out-of-season fertility and its firm white fleece. Flocks supplied early lamb to markets wanting meat ahead of the main spring glut, and this reputation for an extended breeding season travelled with the breed as it spread beyond its home counties.

Exported flocks were established overseas, including in the United States and Australia. In both cases the breed retained its dual-purpose role and its long breeding season, qualities that suited producers wanting more than one lamb crop within a given period.

The Polled Dorset came later. A naturally hornless variation, spotted within Horned Dorset stock, was selected and fixed as a separate type during the twentieth century. The polled form did away with the need to manage horns while keeping the fertility and body type of the original.

The Dorset carries a broad, deep body on short, sturdy legs, giving it a blocky, well-muscled outline suited to meat production. The head is white, the face open and free of heavy wool, and the skin pink. The fleece is white, dense and fairly fine, covering the body in close, even wool.

The two forms differ only at the head. Horned Dorset rams and ewes both grow curled horns, while Polled Dorset animals are naturally hornless. Away from the horns, the two forms share the same colouring, frame and fleece character.

Coat and colouring

The fleece is white throughout, with no coloured markings accepted under the breed standard. Wool from the Dorset is medium in grade and suits general spinning as well as a range of woollen goods. The face, ears and legs stay white and carry little wool, which keeps the head clean and the legs easy to check over. The clip is moderate in weight, in keeping with a breed kept as much for meat as for wool.

The Dorset has a quiet, even temperament. Ewes settle well within the flock, move calmly when worked through a race or pen, and put up with routine handling without much fuss. This steadiness is one reason the breed is often recommended to shepherds still finding their feet.

Around people, Dorsets are good-natured and accept regular contact during feeding, shearing and health checks. They graze steadily rather than rushing about, and mix well with other sheep sharing a paddock. Ewes make attentive mothers and are noted for a good milk supply, which stands their lambs in good stead.

Rams are generally manageable for the breed, though any breeding ram deserves the usual caution and should never be treated as a pet. Being flock animals by nature, Dorsets prefer company and do best kept in groups rather than on their own.

The Dorset is a practical breed that does well on grass and copes with a wide range of conditions. Day-to-day care follows standard British sheep husbandry, with particular attention to the fleece, feet and worm control.

Fleece and feet

• Shear once a year, usually in late spring or early summer, to remove the full fleece.
• Check the fleece for matting, soiling and signs of flystrike through the warmer months.
• Trim hooves as needed, several times a year, to prevent overgrowth and lameness.
• Keep the breech and rear end clean, particularly in the run-up to lambing.

Grazing and movement

• Provide open pasture so the flock can graze and move about freely each day.
• Use rotational grazing across paddocks to keep grass quality up and worm burdens down.
• Allow room for ewes and lambs to move together once lambing is done.

Environment

Dorsets need stock-proof fencing, clean water at all times, and shelter from heavy rain, wind and strong sun. A dry barn or field shelter earns its keep at lambing and in poor weather. Because the breed can lamb outside spring, housing and feed need planning around whichever lambing window the flock follows.

The Dorset is a grazing animal and takes most of its nutrition from pasture during the growing season, turning to hay or conserved forage once grass runs short. Energy needs climb in late pregnancy and during lactation, when ewes rearing lambs may need concentrate feed on top of forage. Growing lambs also do better with extra feed to reach market condition. Sheep need a salt and mineral supply suited to local soil conditions.

Treats and extras

Keep any extra feeding modest. Small amounts of safe greens or root vegetables can be offered now and then, but forage should remain the bulk of the diet. Provide a mineral and salt source formulated for sheep, and adjust trace elements such as selenium or cobalt only where a local deficiency is known. Sudden changes to grain or lush grass can bring on bloat or acidosis, so any increase should be spread over several days.

The Dorset is a generally hardy breed and settles well into managed flock conditions. With good husbandry, ewes commonly live 10 to 12 years, though working breeding lifespans tend to run shorter. Most health problems in the breed are the ordinary concerns of British sheep-keeping rather than anything peculiar to the type, and routine checks prevent most of them.

Preventing problems

• Follow a vaccination and worming programme suited to your region, with guidance from your vet or a body such as the National Sheep Association.
• Trim and check hooves regularly to keep footrot at bay.
• Check the fleece and rear end for flystrike through warm weather.
• Body-condition score ewes before tupping and again before lambing.
• Quarantine and treat any new animals before they join the flock.

The trait that defines the Dorset above all else is its extended breeding season. Unlike most British sheep, which cycle only in autumn, Dorset ewes can come into season across much of the year. This lets a flock lamb in autumn, winter or spring, and it supports accelerated systems aiming for more than one lamb crop within a set period.

Ewes reach breeding age within their first year, and rams mature on a similar timescale. Pregnancy lasts around five months after tupping, and ewes commonly rear twins, with singles and triplets also turning up. The breed has a strong name for good mothering and a reliable milk supply, so ewes generally raise their lambs with little intervention needed.

Lambs are vigorous from birth and grow steadily on the ewe's milk and early grazing. Producers running lambing across the year should plan shelter, feed and labour around whichever window they choose, since lambs born out of season may arrive in colder months and need extra looking after.
