Table 1 Statistical description for residual feed intake and its component traits of genotyped animals used in the study 1

From: Genome-wide association and systems genetic analyses of residual feed intake, daily feed consumption, backfat and weight gain in pigs

  1. 1: The mean residual feed intake was calculated from only genotyped animals. The mean of RFI in the whole population was zero. The negative mean values from current data set implied that these animals have better feed efficiency. The values are shown as mean ± SD.
  2. 2: DFI: Daily feed intake, ADG: Average daily gain, BF: Backfat, RFI1: Residual feed intake 1, RFI2: Residual feed intake 2, dEBV: Deregressed EBV.
