In addition to the EBVs that are published, four selection indexes are also calculated for animals within the TransTasman Angus Cattle Evaluation (TACE).
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.
Selection indexes reflect both the short term profit generated by an animal through the sale of their progeny, and the longer term profit generated by their daughters in a self-replacing cow herd.
All selection index values have been derived using BreedObject technology, as developed by the Animal Genetics & Breeding Unit (AGBU) in Armidale, NSW.
Selection index values are reported as an EBV, in units of net profit per cow joined ($) for the given selection scenario.
