¹CON, basal diet; SB, basal diet + 1 g/kg coated sodium butyrate; MCFA, basal diet + 7.75 g/kg coated medium-chain fatty acids; n-3PUFA, basal diet + coated 68.2 g/kg n-3 polyunsaturated fatty acids. Data are presented as mean ± SEM (n = 6).

^a–cValues in the same row with different small letter superscripts mean significant difference (P < 0.05).
