Poll Dorset
Breed Overview
Poll Dorset is a specialised meat sheep breed widely used in Australian prime lamb production systems. It is valued for rapid growth, early maturity and the ability to produce high-quality lamb under pasture-based conditions. The breed is polled by definition and has become one of the dominant terminal sire breeds in Australia.
Poll Dorset was developed in Australia from the horned Dorset Horn breed, with targeted selection for polledness while maintaining meat production traits. Australian breeding programs place strong emphasis on growth rate, carcase yield, muscling and reproductive efficiency. Genetic evaluation is well established, and the breed is actively recorded through national performance recording systems.
Physical Characteristics
Poll Dorset sheep are medium to large-framed animals with a wide, deep body and pronounced muscling, particularly in the loin and hindquarter. The breed exhibits strong skeletal structure, sound legs and a balanced meat-type conformation. Animals are naturally polled.
The breed has a short to medium-length white wool fleece. Wool quality is secondary to meat production, but fleece management is straightforward under Australian conditions. Poll Dorset sheep are typically shorn annually.
Production Performance
Poll Dorset is classified as a terminal meat breed. Key production traits include:
—
high growth rates from early age,
—
excellent feed efficiency,
—
strong muscling and high dressing percentage,
—
suitability for early lamb turn-off.
Poll Dorset lambs produce carcases with high lean meat yield and favourable fat distribution. Meat quality is consistent, supporting use in both domestic and export-oriented lamb supply chains. Wool is considered a by-product and does not significantly contribute to enterprise income.
The breed demonstrates good fertility and lamb survival, particularly when used as a terminal sire. While not selected primarily for maternal traits, Poll Dorset genetics contribute to reliable lambing outcomes in crossbred systems.
Production Systems and Breeding Use
Poll Dorset sheep perform well in temperate pasture-based systems and are adaptable to a range of management intensities. The breed responds effectively to improved nutrition, making it suitable for both extensive grazing systems and more intensive prime lamb enterprises.
In Australian sheep breeding programs, Poll Dorset is predominantly used:
—
as a terminal sire in prime lamb production,
—
to improve growth rate and carcase traits in crossbred lambs,
—
in structured crossbreeding systems alongside maternal ewe breeds.
Summary
Poll Dorset is a cornerstone meat breed in Australian sheep production, offering predictable growth performance, high carcase yield and strong suitability for terminal crossbreeding systems.
FAQ
No. Poll Dorset is primarily a terminal sire breed used for meat production.
Polledness reduces management risks and labour associated with horned sheep, particularly in intensive systems.
Yes. The breed is known for rapid early growth and early finishing.
While it performs well under good nutrition, Poll Dorset can also be used successfully in pasture-based systems with moderate inputs.
