Accuracies
Accuracy values range from 0-99%. The following guide is given for interpreting accuracy:
EBVs 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 animals own records and pedigree.
50-74% Still subject to the substantial changes with more information, particularly
when the performance of progeny are analysed.
Medium-high accuracy and includes some progeny information. Becoming a
75-90%
more reliable indicator of the animals’ value as a parent.
High accuracy estimate of the animals true breeding value. It is unlikely that
More than 90%
the EBV will change much with the addition of more progeny data.
As a rule, animals should be compared on EBVs regardless of accuracy. However, where tow animals have
similar EBVs the one with the higher accuracy could be the safer choice, assuming other factors are equal.
