  1. The data were expressed as the mean values ± standard deviation (SD)
  2. RFI residual feed intake, FCR feed conversion ratio, ADFI average daily feed intake, ADG average daily gain, 100 kg BF 100 kg back fat thickness, 90 d BW 90 day body weight, 160 d BW 160 day body weight
  3. bThe P values were determined using Welch’s t test (*P < 0.05; **P < 0.01; ***P < 0.001)
