Effect of 3 different levels of quercetin on expression of immuno-related genes in spleen of Arbor Acre broilers compared with those without quercetin. Values are means of 6 replicates of 2 samples each. All data are presented as means ± SE. Different superscript letters indicate significant differences among the means (P < 0.05). TNF-α = tumor necrosis factor alpha; TRAF-2 = TNF receptor associated factor-2; TNFRSF1B = TNF receptor superfamily member 1B; NF-κBp65 = nuclear factor kappa-B p65 subunit; IκB-α = NF-κB inhibitor-alpha; IFN-γ = interferon-γ.
