Dorper

The Dorper is a meat sheep bred in South Africa that has started to draw attention on Irish farms for a simple reason: it sheds its own coat, so there is no shearing bill at the end of the year. The coat is a short mix of hair and wool rather than a proper fleece, and it comes away on its own once the weather turns. Most Dorpers are white-bodied with a black head, though all-white sheep occur too and are registered separately as White Dorpers.

Everything about the breed is geared towards meat rather than wool or milk. Lambs put on weight fast and reach slaughter weight young, and ewes will breed across a long season rather than a tight window. A mature Dorper is medium-sized, with a placid, biddable nature that makes it easy work in the yard, at the mart, or out on the land.

The Dorper is also valued for hardiness. It handles heat, poor feed, and rough grazing better than most wool breeds, which is how the breed spread from the dry farms of South Africa to ranches in Australia and the United States, and, more recently, to smallholdings and commercial flocks in Ireland and Britain, where the wool cheque no longer covers the cost of a shearer.

Who the Dorper suits

The Dorper suits keepers after meat lambs without the work of shearing. It is well proven in commercial flocks in warm, dry country, and it also suits Irish smallholders who want a low-maintenance sheep that holds condition on modest grazing, provided it has dry ground and shelter through the winter. Anyone after wool or milk should look elsewhere, since the Dorper is bred for meat and nothing else.

South Africa bred the Dorper in the 1930s and 1940s. The country's Department of Agriculture wanted a meat sheep able to thrive in the arid and semi-arid stretches of the country, ground where the usual wool breeds struggled against heat and thin feed.

The founding cross put Dorset Horn rams over Blackhead Persian ewes. The Dorset side brought conformation, growth, and a breeding season that ran longer than most, while the Blackhead Persian side brought hardiness, fat reserves, and the ability to get by in dry conditions. The name Dorper is simply the two parent breeds run together.

The Dorper Sheep Breeders' Society of South Africa was set up in 1950 to record pedigrees and promote the breed, and a white-headed line, the White Dorper, was developed along the same lines and is commonly registered alongside the black-headed sort.

Export markets opened up from the second half of the twentieth century on. Australia took to the breed in the late 1990s, the United States around the same time, and Dorpers have since found their way onto Irish and British holdings too, brought in mainly for the no-shear coat and the easy fleshing rather than for the heat tolerance that suits them so well back home in South Africa.

The Dorper carries a deep, well-muscled body on short, strong legs. The frame is rectangular and set low to the ground, with plenty of width through the loin and hindquarters, all of which points to a sheep bred for meat rather than show. The head is on the short side, and both polled and horned animals turn up in the breed, though most are polled or carry only small horns.

The coat is what marks the breed out. It is a short mix of hair and wool that loosens and comes away of its own accord once the weather warms, so there is no need to bring in a shearer. How much wool an individual carries varies from one animal to the next, and from one season to the next.

Coat and colours

The standard black-headed Dorper is white-bodied with a black head and neck, and the two colours should meet in a clean, well-defined line. The White Dorper is white all over. The covering itself is short and shaggy rather than a proper wool fleece, and it falls away naturally as the weather turns milder. Dark pigment on exposed skin, around the eyes and under the tail especially, is preferred, since it gives some protection against strong sun, a lesser concern on an Irish hillside than on the South African veld, but still a point breeders look for.

The Dorper has a quiet, level temperament. The sheep are docile and settle quickly once moved or penned, which makes jobs such as drenching, foot-trimming, and weighing far less of a battle than with flightier breeds. They flock well and stick to a routine, so a large number of them is little harder to manage than a small one.

Around people the breed is generally placid and not given to aggression, though rams can become more assertive during the breeding season and are best handled with the usual care. Ewes mind their lambs closely and stay near them. Dorpers run alongside other grazing stock, cattle included, without trouble, and they take a stranger or a new handler in their stride once they are used to a routine.

Grooming

• No shearing needed, as the coat sheds itself naturally each year.
• Check the coat is shedding cleanly come spring, and pull away any large loose patches that have not come off on their own.
• Trim hooves as needed, usually a handful of times a year, to stop overgrowth and lameness setting in.
• Check the skin and any pigmented patches for sun damage, wounds, or flystrike.

Exercise

• Dorpers get all the activity they need from grazing, so there is no call for separate exercise.
• Give the flock enough field or range to move about and forage freely.
• Rotate grazing where possible, to keep pasture in good heart and cut down on parasite buildup.

Environment

The Dorper is at its best in hot, dry conditions and will get by on rough grazing that would not carry many wool breeds. It still needs constant access to clean water, shade during a heatwave, and basic shelter from cold rain and wind, and on an Irish holding it is the shelter and drainage that matter most day to day. The breed tolerates a good range of conditions, but it does better on warm, dry ground than on cold, wet pasture, where the risk of foot problems climbs sharply, so dry lying ground counts for more here than it would on a South African farm.

The Dorper is not a fussy grazer. It takes to pasture, crop residues, and scrubby vegetation alike, and on decent grazing an adult can meet most of its needs from forage alone, part of why the breed suits a low-input system so well. Feed should step up in quality and quantity during late pregnancy, through lactation, during growth, and in any dry spell when grass runs short. Grass runs short less often on Irish pasture than in most places the Dorper is farmed, but a dry summer will still catch a flock out.

Keep clean water available at all times, along with a salt or mineral supplement suited to local soils. Mineral levels vary a good deal from one Irish county to the next, so it is worth finding out what the home ground tends to be short of.

Treats and supplements

Good hay, a sheep mineral lick, and a small amount of grain cover most flocks' extra needs. Bring in any new feed gradually, over a week or more, to give the rumen time to adjust. Treats such as fruit or vegetable scraps are fine in small amounts, so long as none of it comes from anything on the toxic-plant list.

The Dorper has a name as a hardy, low-maintenance breed, with decent resistance to many of the common sheep ailments. Under sound management, animals commonly reach 10 to 12 years old, though breeding ewes are usually culled sooner, once production starts to tail off. Most of the health problems seen in the breed are the ordinary run of sheep ailments rather than anything peculiar to the Dorper itself.

Preventive care

• Follow a vaccination programme, clostridial cover included, on your vet's advice.
• Watch for worms and drench on need, not by a fixed date on the calendar.
• Trim and check feet regularly, and especially after a wet spell.
• Keep tails and rear ends clean to cut the risk of flystrike.
• Feed ewes properly in late pregnancy to head off metabolic disease.

The Dorper matures early, and ewes can go to the ram from around seven to twelve months old, once they have reached a fair body weight. One feature that sets the breed apart is its long, largely non-seasonal breeding ability, which lets ewes lamb more than once a year under good management and an accelerated mating system, unlike most sheep kept in Ireland, which breed to a tighter, autumn-tupped, spring-lambing pattern.

Gestation runs to about five months, somewhere between 145 and 150 days. Ewes usually rear a single lamb or twins, with twins more common in mature, well-fed ewes. Lambing tends to go easily, and ewes show a strong mothering instinct, cleaning and feeding lambs with little need for anyone to step in.

Lambs are strong and grow on fast, helped by good milk from the ewe and early access to grass. That quick growth to market weight is one of the main reasons the breed is kept at all. Lambs are usually weaned at around three to four months old, after which they carry on out on pasture with some meal alongside.
