1CON, control; PEX, DFM applied before extrusion; DFM applied as coating at low dose; PCM, DFM applied as coating at moderate dose; PCH, DFM applied as coating at high dose.
2Total SCFA (acetate + propionate + butyrate); individual SCFA is expressed as a percent of total SCFA.
3Total BCFA (isobutyrate + isovalerate + valerate); individual BCFA is expressed as a percent of total BCFA.
4P-value represents type 3 test of fixed effects for diet.
