ACCURACY RANGE INTERPRETATION
EBV should be considered as a preliminary estimate. It could change
less than 50%
substantially as more performance information becomes available.
Medium accuracy, usually based on the animal’s own records and
50-74% pedigree. Still subject to substantial changes with more information,
particularly when the performance of progeny are analysed.
Medium - high accuracy and includes some progeny information.
75-90%
Becoming a more reliable indicator of the animal’s value as a parent.
High accuracy estimate of the animal’s true breeding value. It is
more than 90% unlikely that the EBV will change much with the addition of more
progeny data.
