Annual Enhancements to TransTasman Angus Cattle Evaluation – December 2020

Members are advised that a number of enhancements have been implemented into the analytical software that is used to calculate Estimated Breeding Values (EBVs) within the mid December 2020 TransTasman Angus Cattle Evaluation.  

Updated EBVs from this analysis are expected to be published shortly. 

The enhancements are part of the ongoing maintenance and improvement to the genetic evaluation and will result in the calculation of EBVs that better predict the genetic merit of Australian Angus animals. 

The analytical enhancements that have been implemented broadly fall into four categories: 

  • Improvements to Handling of Genomic Information
  • Updating of Selection Indexes
  • Improvements to Structural Soundness EBVs
  • More Routine Publication of Research Breeding Values  

The enhancements that have been implemented have resulted in considerable changes to the EBVs, particularly the Structural Soundness EBVs, and selection index values for a large number of animals.
