Poll Dorsets are short wool, meat producing
sheep that were developed in Australia between 1937 and 1954 with the aim of
breeding a true Dorset type sheep without horns. They were developed at a
property called Valmore in Whitemore, Tasmania, a noted center for pedigree
livestock stud farms. Poll Dorset resulted from the introduction of Corriedale
and Ryeland blood into the Dorset Horn.
Their main distinguishing features are its
hornless appearance, long, lean square body set on short legs, pink skin and
'spongy' short-stapled wool. Poll Dorsets produce a fleece of white, dense
downs type wool of around 30 microns fiber diameter and they have a white wool free
face.
Poll Dorset rams are the most commonly used
sire for the production of prime lambs in Australia. Ewes are noted for their
high fertility, mothering and milking ability. The characteristics of the breed
such as rapid growth rate, superior fleshing and muscular development make them
ideally suited for the meat trade. Lambs sired by Poll Dorsets can satisfy the
lightweight Middle Eastern market, the local market or the export market to the
USA at 20 to 25 kg or heavier. Poll Dorset carcasses have excelled in
Australian carcass competitions having very good eye muscle and a good lean
meat to fat ratio. Poll Dorset genes have also been a major contributor to the
developing White Suffolk breed and almost all other prime lamb composite breeds
in Australia.
Export sales have been made to Africa,
Asia, Europe and North and South America.
In 1992 Meat Elite Australia was established
by a group of Poll Dorset breeders to share genetics, and progeny test elite
young sires to identify animals that will benefit the Australian sheep meat
industry.
The Australian Poll Dorset is not to be
confused with the Polled Dorset that was developed at North Carolina State
University in the early 1950s.
