1 N = total number of animals used in the association analyses.
2ADG = average daily gain: recorded in kg per day from start to end of the finishing period.
3DMI = dry matter intake: recorded in kg per day from start to end of the finishing period.
4MMWT =midpoint metabolic weight: expressed in kg.
5RFI = residual feed intake: expressed in kg per day.
6RFIf = residual feed intake adjusted for backfat: expressed in kg per day;
BFat7= backfat: recorded as fat depth at the end of the finishing period in millimeters.
