GLOSSARY OF TERMS USED
Birth Weight EBVs
These indicate the estimated difference in average birth weight (kg) of progeny. Positive values indicate heavier than the average birth weights. Birth weights reflect pre natal growth potential and may be an indicator of calving ease. On average, progeny will inherit half of the sire's birth weight EBV.
200 Day Weight EBVs
This is the expected difference in the average weaning weight due to the sire. The calves will inherit half of this figure in kg with the other half coming from the EBV of the dam. Positive values indicate heavier than average weaning weight.
400 Day Weight EBVs
This is the expected difference in the average yearling weight and indicates the post weaning influence of the sire. Positive values indicate heavier than average yearling weights.
600 Day Weight EBVs
This is the expected difference at the normal killing age. Positive values indicate heavier than average killing weights.
