^aValues are least squares means ± SEM.

^b HRFI, high RFI; LRFI, low RFI.

^cResidual feed intake was determined between days 42 and 91 pw (n = 8/RFI rank).

^dGene names: AMPK, AMP-activated protein kinase; FASN, fatty acid synthase; GLUT2, solute carrier family 2 (facilitated glucose transporter), member 2; IL, interleukin; SRBEF1, sterol regulatory element binding transcription factor 1; PPARG, peroxisome proliferator-activated receptor-γ; SGLT1, solute carrier family 5 (sodium/glucose cotransporter), member 1; SOCS, suppressor of cytokine signaling; TGFB1, transforming growth factor-β 1; TNFA, tumor necrosis factor-α.
