Ultrafine Merino Company

FOUNDATION.

Bloodlines predominately Merryville.

The Ultrafine Merino Company (JV Ultra Fine) aim is to be a market leader in reducing micron while holding fleece weight and body weight. 

In the early 1980’s, in partnership with Agresearch, 12 properties screened their flocks for the finest ewes.

  • Ewes were screened in succeeding years until the introduced ewes were no longer fine enough and the flock was closed.

  • The nucleus was run on Tara Hills Research Station until 2008 when it was shifted to Earnscleugh.

  • We continually search for outside genetics but have not found any fine enough in the last 10 years.
  • As the Earnscleugh Ultrafine flock is closely related there is now some swapping of genetics.
  • A search of the MERINO SELECT Australasian breeding values site will show most of the top 150
  • Sires trait leaders for micron are either JV Ultra fine or Earnscleugh.
  • Rams are sold by marble draw to shareholders and then surplus rams are available to outside buyers.

AIMS.

Our aim is to reduce micron, hold fleece weight and body weight, and increase staple strength.
The wool type aim is a free growing, sheeny, nourished, stylish and with good crimp definition.
