1Ratio of pen variance and phenotypic variance
2ADG2 = average daily BW gain from 30 to 100 kg; BF = backfat; BC = body conformation; FCR = food conversion ratio; RFI1 = residual feed intake 1
(calculated based on regression of DFI on initial test BW and ADG2); RFI2 = residual feed intake 2 (calculated based on regression of DFI on initial test BW,
ADG2, and BF); DFI = daily feed intake from 30 to 100 kg; NVD = number of visits to feeder per day; TPD = total time spent eating per day; FR = feed intake
rate; FPV = feed intake per visit; TPV = time spent eating per visit.
