A comprehensive report and a lot of data. Team data at the back of the report is de-identified, but the bloodlines are listed. Interesting to see the difference between Autumn, Winter and Spring drop averages.

Craig Wilson & Associates convenes the Peter Westblade Memorial Merino Challenge. It is Australia’s largest commercial evaluation of Merino genetics.

It is a two-year genetic evaluation measuring wool, meat and growth traits of individual Merino wethers. Over the two years, more than 60,000 individual records are collected.

The challenge comprises of two components:

Wool challenge

  • 50 teams of 15 wether lambs
  • The wool challenge report will come later in 2018. Refer to the website for past reports.

Meat challenge

  • 50 teams of 15 wether lambs

Over 20,00 individual records are collected to measure commercially relevant growth and carcase traits. Traits measured included:

  • Body weights
  • Final body weight
  • Dressing percentage
  • Age
  • Carcase weight
  • Fat depth at GR
  • Eye muscle depth
  • Fat
  • Skin wrinkle

Bloodlines included:

  • Pastora
  • Leachim
  • Hazeldean
  • Kenilworth
  • Pooginook
  • Centre Plus
  • Willandra
  • Tupra

Key results of the 2016 meat challenge include:

  • Economic variation between teams for carcase value was 43% between the top and bottom teams.
  • Growth rates averaged 118grams/head/day adjusted for age, the variation of individual lamb growth rate ranged up to 292grams/head/day.
  • The growth rates were slightly lower in 2016 compared to previous years (2010, 2012 and 2014).
  • The average final body weight was 52.7kg and 47.3kg for the Autumn and Winter/Spring drops respectively.
  • The weather lambs average dressing percentage was 46.6% with an average carcase weight of 23.4kg.
  • Very high correlation between carcase value, carcase weight and start weight, and a high correlation between carcass value, body length and dressing percentage.

The results of the study provide information to entrants and the wider industry.
