| Traits | HRFI | LRFI |
|---|---|---|
| ADFI (g/d) | 287.69±21.27a | 262.83±20.25b |
| ADG (g/d) | 129.53±8.99 | 139.5±10.36 |
| MBW0.75 (g/d) | 262.53±10.96 | 351.94±10.96 |
| FCR (g/g) | 2.22±0.02a | 1.88±0.01b |
| RFI (g/d) | 12.31±5.82a | −14.78±6.34b |
RFI, residual feed intake; ADFI, average daily feed intake; ADG, average weight gain; MBW0.75, metabolic body weight; FCR, feed conversion ratio; HRFI, highest RFI; LRFI, lowest RFI.
The number of samples of the HRFI and LRFI groups is 10, respectively.
