Self-Replacing Index ($) - Estimates genetic differences between animals in net profitability
      per cow joined for a self-replacing commercial herd, targeting the production of grass finished
      steers. Steers are assumed marketed at 525 kg live weight (280 kg carcase weight and 10 mm
      fat depth) at 16 months of age.
      AngusPure Index ($) – Estimates genetic differences between animals in net profitability
      per cow joined for a self-replacing commercial Angus herd, targeting the production of grass
      finished steers for the AngusPure programme. Steers are assumed marketed at 525 kg live
      weight (280 kg carcase weight and 10 mm fat depth) at 18 months of age with a significant
      premium paid for marbling.
      Heifer/Dairy Terminal Index ($) – Estimates the genetic differences between animals
      in net profitability per female joined in an example herd where all progeny are marketed. All
      progeny are marketed at approximately 510 kg live weight (280 kg carcase weight and 7 mm
      fat depth) at approximately 24 months of age.

      Accuracy

      Accuracy (%) is based on the amount of performance information available on the animal
      and its close relatives - particularly the number of progeny analysed. Accuracy is also based
      on the heritability of the trait and the genetic correlations with other recorded traits. Hence
      accuracy indicates the “confidence level” of the EBV. The higher the accuracy value the lower
      the likelihood of change in the animal’s EBV as more information is analysed for that animal
      or its relatives. Even though an EBV with a low accuracy may change in the future, it is still
      the best estimate of an animal’s genetic merit for that trait. As more information becomes
      available, an EBV is just as likely to increase in value, as it is to decrease.
      Accuracy values range from 0-99%. The following guide is given for interpreting accuracy:
