Skin and wool

We select for soft, smooth, wrinkle free skins that produce lustrous, deep, bold crimping wools that are perfectly aligned and very fast growing.

These characteristics are indicative of high levels of density and length and ensure the quality and quantity of fiber is maintained throughout the life of the sheep.

Early Maturity

AI0E0858Early maturity is important for lamb survival, for wether lamb sales and for ewe lamb joining’s.

In 2016 our ewes, maidens included, conceived 155% of lambs. It’s very important to our business that a high number of those fetuses are converted into live, fast growing lambs at weaning time.

With more lambs to play with we have more wether lambs to sell. With good early maturity in those lambs we can then achieve good conception rates in our ewe lambs when joined at 8 months. Combining high fertility with early maturity produces exceptional genetic gain.

Fleece weight

Mumblebone flocks are cutting 6 to 7.2 kg’s, depending on season and country.

Breed aims

The Mumblebone sheep are bred to combine early maturity and high fertility with exceptional wool quality.


Structure is very important to us and a visual assessment of all Mumblebone ewes is carried out every year.


Rapid genetic gains, and business profitability are both driven by high reproduction rates. All Mumblebone ewes are scanned every year to identify twin-bearing ewes.

Lambs are identified as either a twin or single and this information is then used at classing time with preference given to twin lambs.

Any ewe that either scans dry, or is found to have lambed and lost is sold. No second chances are given.


Mumblebone ewes have a very calm temperament. A calm ewe is more likely to conceive and less likely to be frightened away from her lamb.

A calm ewe will also burn less nervous energy when handled leaving greater energy reserves for milk, meat and wool production.
