The parameters for the allometric function relating CW to BW were impacted by sire line and sex (p < 0.
Significant sire line by sex interactions existed for allometric equation parameters, (A for loin depth, B for backfat depth, and both A and B for Lean % and fat-free lean mass).
The significant sire line by sex interactions for the allometric equations indicated that the sex differences in which Lean % decreased per kilogram in CW differed amongst the 4 sire lines.
