Note: l-ERFI = low residual feed intake group; H-ERFI = high residual feed intake group; E-RFI = estimated residual feed intake at 70 to 100 weeks of age. Letter annotations are shown in Table 1. a-c means values with no common superscripts within each row differ significantly (P < 0.05) when tested with Duncan’s test. Values are expressed as “mean ± standard deviation”.
