p-value as calculated by t-test.
ABF, average of back fat thicknesses (mm) measured at three points between 6th and 7th ribs (6th–7th BF) and at the10th rib (10th BF).
LMA, loin muscle area (cm²) measured between the 10th and 11th.
FE, feed efficiency; FCR, feed conversion ratio; RFI, residual feed intake; DFI, daily feed intake; ADG, average daily gain over the assessed feeding period; BW, body weight; AMBW, average metabolic body weight; BF, backfat thickness.
