The 2 traits used to calculate the predicted
feed intake by multiple linear regression were
ADG (ADG1) from 35 to 95 kg of BW and backfat thickness
measured by ultrasonic scanning (UBT), averaged
from 6 measures at 95 kg ofBW(right and left shoulder,
right and left midback, right and left loin), using an
ALOKA SSD-500 echograph (Aloka, Cergy Pontoise,
France).
