About
The Dorset Sheep (Ovis aries) is a highly versatile breed in the family Bovidae, prized for both its meat and wool. Originating in southern England, particularly the counties of Dorset, Somerset, Devon, and Wales, it is one of the oldest established sheep breeds still widely raised today. Dorset sheep are especially valued for their unique ability to breed out of season, making them a favorite among farmers for year-round lamb production.
Medium to large in size, Dorset rams typically weigh 225–275 pounds (100–125 kg), while ewes average 150–200 pounds (70–90 kg). They are sturdy, white-faced sheep with short, fine wool that covers most of the body. Their fleece, averaging 27–33 microns in diameter and 3–5 inches (8–13 cm) in staple length, produces a dense, springy wool well suited for knitting and general textiles.
The breed is available in two main types: Horned Dorset, the traditional variety with distinctive curled horns, and Polled Dorset, a hornless strain developed in the 20th century in the United States. Both varieties share the same productive traits, but Polled Dorsets are now more widespread due to ease of handling.
Dorsets are renowned for their reproductive efficiency. Unlike most sheep breeds, they can lamb up to three times in two years, and ewes often give birth to twins. This trait has made them central to commercial meat production systems. Dorset lamb is known for being tender, lean, and flavorful, making it highly marketable.
Adaptable and docile, Dorset Sheep thrive in varied climates and grazing conditions. They have been exported worldwide and remain especially popular in North America, Europe, and Australia. Their combination of breeding flexibility, high-quality meat, and useful wool has secured their place as one of the most important and enduring sheep breeds globally.

White face free of wool, with a broad muzzle. They have a calm, alert expression and strong jaw.
Body:
Well-proportioned with a deep chest, straight back, and muscular build. Their body type supports efficient meat production.
Tail:
Medium in length, typically docked in managed flocks.
Horns:
There are two varieties: Horned Dorset (rams have large curled horns, ewes smaller horns) and Polled Dorset (naturally hornless).
Size:
-
Height: 26 to 32 in (66 to 81 cm) at the shoulder.
-
Body Length: 38 to 46 in (96 to 117 cm).
Weight:
-
Adult Ewes: 130 to 180 lbs (59 to 82 kg).
-
Adult Rams: 225 to 275 lbs (102 to 125 kg).
The Dorset Sheep’s muscular frame, quality wool, and dual-purpose adaptability make it one of the most popular and productive sheep breeds worldwide.
Reproduction
Dorset Sheep are renowned for their reproductive versatility, especially their ability to breed out of season.
1. Mating and Breeding Season:
Unlike many sheep breeds that breed seasonally, Dorsets can mate year-round, allowing for multiple lambing opportunities each year under managed systems.
2. Estrus Cycle:
Ewes cycle every 16 to 17 days, with heat lasting 24 to 36 hours. Rams are active breeders and can serve flocks effectively.
3. Gestation:
The gestation period lasts about 147 to 150 days (approximately 5 months).
4. Birth of Lambs:
Ewes commonly give birth to 1 to 2 lambs, though twins are frequent in well-managed flocks. Multiple lambings per year are possible due to their non-seasonal breeding.
5. Maternal Care:
Dorset ewes are known for excellent maternal instincts and strong milk production, contributing to high lamb survival and rapid growth rates.
6. Weaning and Maturity:
Lambs are weaned at 2 to 3 months. Ewe lambs may reach breeding age at 7 to 8 months under favorable nutrition.
7. Reproductive Strategy:
Their ability to breed year-round, combined with strong maternal care, makes Dorset Sheep one of the most productive and flexible sheep breeds for meat and flock expansion.
Lifespan
Dorset Sheep are hardy, long-lived animals, prized for their productivity and resilience in managed farming systems.
Lifespan in the Wild/Free-Ranging:
In traditional grazing systems, they live around 8 to 10 years, with peak productivity in meat and lambing during their first 5 to 6 years.
Lifespan in Captivity/Farm Management:
With proper care, balanced nutrition, and veterinary management, Dorsets can live 10 to 12 years, with some individuals reaching up to 14 years.
Life Cycle Dynamics:
-
Lambhood: Weaned at 2 to 3 months, with fast growth.
-
Breeding Age: Ewes mature at 7 to 8 months, rams slightly later.
-
Prime Years: Most productive between ages 2 and 6, especially for year-round breeding.
-
Senior Age: Fertility and physical condition decline gradually after 7 years.
Threats to Longevity:
-
Parasites: Internal and external parasites can reduce health and lifespan without control.
-
Predation: Free-grazing flocks are vulnerable to dogs, coyotes, and other predators.
-
Nutritional Stress: Poor forage or drought can impact survival and productivity.
The Dorset Sheep’s longevity, combined with their ability to breed year-round, ensures steady flock growth and reliable productivity for farmers worldwide.
Eating Habits
Dorset Sheep are adaptable grazers with efficient feeding habits, supporting their strong growth and reproductive capacity.
Diet:
They feed primarily on grasses, clovers, and legumes, but also consume forbs, weeds, and crop residues. Diet quality directly affects both meat production and milk yield.
Foraging Behavior:
-
Flexible Grazers: Thrive in pasture, rangeland, and rotational grazing systems.
-
Selective Feeders: Prefer tender grasses and legumes but will graze coarser plants when forage is limited.
-
Efficient Converters: Known for efficiently turning forage into both high-quality meat and milk.
Feeding Method:
Their narrow muzzle and split lip allow them to graze close to the ground, efficiently harvesting short grasses and nutritious plants.
Group Feeding:
Dorsets graze in flocks, maintaining strong social instincts and making them easy to manage.
Daily Patterns:
Most active at dawn and dusk, resting during midday heat.
Ecological Role:
By consuming diverse plant material, Dorsets help maintain pasture health, manage weeds, and encourage regrowth in sustainable grazing systems.
Uniqueness

Dual-Purpose Breed:
They provide both high-quality wool and lean, flavorful meat, making them valuable for diverse farming operations.
Two Varieties:
Dorsets exist in both Horned and Polled types, with the latter developed in the 20th century and now widely popular for ease of management.
Strong Maternal Qualities:
Ewes are excellent mothers with abundant milk production, contributing to high lamb survival and growth rates.
Adaptability:
They thrive in a wide range of environments, from upland pastures to intensive farming systems, showing resilience in varied climates.
