Performance

Bellaine sheep are performance-tested and data is used as a strong component of our selection process.

The traits we directly measure and score are listed below.

Data from all sheep is used to produce Australian Sheep Breeding Values (ASBV), which allow you to directly compare the genetic merit of Bellaine sheep to hundreds of thousands of Merinos nationally.

You can directly view our Sheep Genetics sale catalogue here: Bellaine 2021 Sale Ram ASBVs.

or ASBVs on any of our sheep can be viewed live in the MERINOSELECT section of the Sheep Genetics website:

Once there you can either enter a 16 digit sheep ID (see below) into the ID box, or else select the Advanced search option, then type Bellaine into the stud box and choose your other search options before clicking search.

Example of a Bellaine 16-digit number: 5050452005050134

50=Merino; 5045=Bellaine stud number; 2005=year of birth; 050134=6 digit tag starting with short year of birth

At shearing (10 months)

  • mid side sample taken for
    • Fibre diameter (plus SD, CV, curvature)
    • Yield
    • Staple strength
    • Staple length
