1Estimated Breeding Value of a sire for the yearling Eye Muscle Depth (EMD) trait measured by progeny testing. EBVs were derived from data extracted from LAMBPLAN [45].

2EMD EBV (mm) is a measure of the difference in the trait from the industry-wide contemporary average set in 2001.

3Accuracy reflects the number of progeny with phenotype information used to calculate the EBV. Accuracy ranges from 0-99% and indicates the probability of an EBV changing with the addition of more progeny data. The magnitude of possible change decreases as accuracy increases. Accuracy below 75% is regarded as low, between 76-90% as medium and above 90% as high.

4Percentile ranking of the sire amongst contemporaries for the EMD trait.

5Sire group V was classed in the low muscling sire group because of its percentile ranking relative to sires in the high muscling group.
