Summary
Including genomics in genetic evaluations can increase estimated breeding values' (EBV) accuracy and selection response, especially for hard-to-measure, sex-limited traits and traits expressed later in life.
Objectives
• descriptions of current and historical reference populations
• provide reference population design support to current reference populations
• data analysis to add value to current reference populations
• undertake research related to the design of reference populations.
Key findings
Descriptions of Australian beef genomic reference populations were compiled to capture the reference population design and summarise the data generated. This insight will help guide future investments in reference populations to ensure they deliver the greatest impact, while also enhancing the use of existing populations to drive genetic progress.
Benefits to industry
The key outcome for industry from this research was the creation of evidence-based recommendations to guide future investment in genomic reference populations.
MLA action
To support the sustainability of reference populations, it is important to regularly monitor the genetic connections between reference animals and those currently included in evaluations, helping preserve the effectiveness of genomic selection.
Future research
This project has demonstrated additional investment is needed in beef reference populations for traits that are difficult to measure, such as abattoir carcase traits, female reproduction and mature cow weight, to expand their size and strengthen their genetic links to the broader beef population.
