PERFORMANCE

 
Bellaine sheep are performance tested and data is used as a strong component of our selection process.
 
See below for what we directly measure and score.

Maiden ewes (retained 2 year olds - 2014 drop at August 2015) FD 16.0 micron  GFW 3.8 kg

11 month old rams at first shearing FD 14.3 micron  GFW 2.1 kg

 
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 2016 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 into the ID box or else down further, select the Advanced search option, then type Bellaine into the stud box to the right and choose your other search options before clicking search at the bottom.
 
Example of a Bellaine 16-digit number:
5050452005050134
50=Merino; 5045=Bellaine stud registration number; 2005=year of birth; 050134=6 digit tag starting with short year of birth
