Table 2. Short chain fatty acids concentration (SCFA; mmol/kg wet sample) in the distal colon of pigs infected or not with Ascaris suum, and either fed a control diet or a diet supplemented with 5% grape pomace (GP).
Each group n = 6. SCFA in bold and italicised are significantly impacted by infection and/or diet.
