^a,bMeans within a column and main effect not sharing a common superscript are significantly different by Tukey's test (P ≤ 0.05).

¹Control, negative control with no additives; Monensin, basal diet supplemented with 100 ppm of monensin; OE, basal diet supplemented with 750 ppm of OE.

²TCA, Taurocholic acid; TCDCA, Tauroursodeoxycholic acid; TLCA, Taurolithocholic acid; AVCA, Avicholic acid; CA, Cholic acid; CDCA, chenodeoxycholic acid.

³SEM, standard error of means (n = 6).

⁴P- values are from square root data transformation analysis.
