Phenotypic differences between sire groups (low RFI sire–high RFI sire) compared with expected progeny difference based on bull breeding values.

Differences between sire progeny groups for growth, intake, feed efficiency, feeding behavior, methane production, and carcass traits are provided, including trait, trait mean, mean difference between sire groups, P-value for that difference (P<0.05 bolded), and expected progeny difference based on sire breeding values where available.
