ABOUT

  • The SRS Merino is naturally resistant to fly strike and free from mulesing. They have high fleece weight and are easy to shear. The wool produced is fine, exquisitely soft and lustrous.

    SRS Merinos are selected primarily for high fibre density and length, producing a unique patterning of wool follicles in the skin, with closely packed and long fibre bundles of high crimp amplitude and low crimp frequency.

    This selection process simultaneously increases fleece weight and the wool’s processing qualities. The result, farmers sell more wool at a higher price.

    By selecting for this fleece type, the SRS Merino is plain bodied and open faced. The sheep are naturally robust, have more lambs and much reduced lamb losses.


    SRS Merino are bred via a scientific

    process called SRS, developed and pioneered by research veterinarian, Dr Jim Watts. This quantitative technology enables transformation of classic Merino flocks, into SRS Merinos within 5 years.

    The SRS Merino is a superior, ethically produced and natural successor to the classic wrinkly Merino sheep commonly found within Australia.

THE SHEEP

  • SRS Merino sheep are plain bodied animals with a distinctive fleece structure and loose, thin skin that sets it apart from other Merino sheep.

    This the outcome of selecting the sheep for high density and length of wool fibres. The response to selection is rapid. We have already doubled the length of fleece grown by the sheep and increased the fibre density by about 50 %.

    The added benefits of pursuing this breeding program have been that the sheep:

    • Are naturally resistant to fleece rot and all forms of fly strike, and do not need to be mulesed.
    • Are easy to shear
    • Have many more lambs and many fewer lamb losses
    • Produce wool that is very soft, lustrous and deeply crimped and processes exceedingly well
    • Are fit and robust

    The series of photographs that follow illustrate these features.

THE WOOL

  • The SRS® Merino fleece consists of fine fibres that are highly aligned and long. The fibres are very uniform in diameter and length to each other, and are remarkable in having low variation in diameter along the length of the fibres.

    The fibres also have high crimp amplitude (“deep crimp”) and low crimp frequency (“bold crimp”) and are notable for high tensile strength and elasticity.

    The surfaces of the fibres are smooth and very soft, being formed by long cuticular scales of low scale height.

    The fleeces grow so rapidly that many SRS® Merino sheep are shorn twice a year, reaching a combing length of 80 to 90 millimetres in six months.

Processing trials in six global markets by a large vertically integrated Japanese processor have consistently shown major efficiencies of using SRS® fibre as shown below.

Mill Number of
trials
Wool top
Hauteur Short fibre content Noil
Italy
(17.3 to 17.9 microns)
4 + 11% -12% to -25% -7% to -13%
Japan
(18.7 to 20.7 microns)
6 + 4% to + 9% -21% to -35% 0% to -25%
Australia
(18.2 to 18.7 microns)
4 + 14% -58% – 39%

The Hauteur (average fibre length) of the wool top was improved markedly whilst the short fibre content and noil wastage were decreased considerably. Yarn breakages during spinning were reduced by 20% to 30%. The company described the fabric produced as soft and silky with very good natural strength and elasticity.
