Docility EBV (%) is an estimate of the genetic differences between
animals in temperament. Docility EBVs are expressed as differences in the
percentage of progeny that will be scored with acceptable temperament (ie.
either “docile” or “restless”).
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:
