¹Data are means ± SEM, n = 8.

²CON, control basal diet; LPS, LPS challenged broilers fed CON; LPS+T1, LPS challenged broilers fed CON supplemented with 5 g/kg taurine; LPS+T2, LPS challenged broilers fed CON supplemented with 7.5 g/lg taurine.

³Expressed in arbitrary units. The expression of each target gene for the CON group was assigned a value of 1 and normalized against beta-actin.

^a,bMeans within the same row with no common superscript differ significantly (P < 0.05).
