Research Selection Indexes
The research selection indexes have been developed for industry review and feedback prior to potential implementation into the TransTasman Angus Cattle Evaluation. Updates have been made to the selection indexes to ensure they continue to represent more scenarios and parameters and utilise the most current analysis tools.
Aligning with your program
When utilising selection indexes, members are advised to select the Selection index that is most aligned with the system their operation operates in.
Using Selection Indexes
Angus Selection Indexes should be used as an initial filtering tool for potential selection candidates, before specific breeding objective criteria is applied.
Providing balanced selection decisions
The selection indexes assist in making “balanced” selection decisions, taking into account the relevant growth, carcase & fertility attributes of each animal to identify animals that are most suitable for use within a particular commercial enterprise.

What is a Selection Index?
Selection indexes aid in the selection of animals for use within a breeding program where there are several traits of economic or functional importance by providing an overall “score” of an animal’s genetic value.
Introduction to Research Breeding Values & Research
RBVs (Research Breeding Values) are EBVs in development. RBVs are produced as part of the development of EBVs for new traits, which enable the refinement of both the performance recording information and the analytical software used in their calculation.
Wrapping up EBVs describe the difference, not the actual
Over the course of the last few weeks, Angus Australia has put together a series of resources breaking down “EBVs describe the difference, not the actual”. Angus Australia members are encouraged to contact Angus Australia in regard to any questions they have about Estimated Breeding Values.
EBVs describe the difference, not the actual: Part 2
Last week, we explored one reason why a bull’s physical performance cannot be used to validate his EBVs and looked at the impact of non-genetic factors on the physical performance of an individual.
EBVs describe the difference, not the actual
EBVs are a powerful tool to support breeders when making breeding and selection decisions. It is however important when utilising EBVs that we understand the tool and what information it provides,
