^a,b,cMean values within a row with unlike superscripts differ (P < 0.05).

¹FM = flaxseed meal-containing diet; OH = oat hulls-containing diet; normalized BA concentration (mmol/kg DMI) = BA concentration (mmol/kg DM) × (titanium in diets ÷ titanium content in feces or ileal digesta).

²Calculated as: deoxycholic + isodeoxycholic + lithocholic + ursodeoxycholic acid.

³Calculated as: chenodeoxycholic + cholic + deoxycholic + isodeoxycholic + lithocholic + ursodeoxycholic acid.
