EBVs Explained

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%.
As a rule, animals should be compared on EBVs regardless of
accuracy. However, where two animals have similar EBVs the
one with higher accuracy could be the safer choice, assuming
other factors are equal.
