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:
