Customised ASBVs matches rams to their environment in WA

Monday 14th of January 2013

Key results from using ASBVs:

Over a 10 year period, selecting rams using the customised Australian Merino Society (AMS) Wool Production ASBV Index, the Hobbs family aim to achieve:

  • 0.5 kg increase in clean fleece weight
  • 20% improvement in number of lambs weaned,
  • 2kg increase in bodyweight and
  • 5mm increase in eye muscle depth


Commercial producer Brett Whittington has also improved his flock’s body score by 0.75 and reduced micron from 21.3 to 20 using the AMS WP ASBV index

The long-term use of Australian Sheep Breeding Values (ASBVs), combined with stringent visual assessment, is effectively matching rams to their breeding environment and bolstering productivity in Western Australian flocks.
