Bar charts of jejunal mRNA expression levels of nuclear factor erythroid 2-related factor 2 (Nrf-2), glutathione peroxidase 1 (GPx1), superoxide dismutase 1 (SOD1), and catalase (CAT) at 24 days of age observed in broiler chickens infected with a mixture of Eimeria species at 14 days of age. a–dDifferent letters in the same histogram indicate significant differences among groups according to Tukey’s multiple range test (P < 0.05). NC, uninfected control group with commercially recommended levels of inorganic trace minerals (ITM). Coccidiosis-challenged groups included: PC, commercially recommended levels of ITM; SAL, basal diet with commercially recommended levels of inorganic trace minerals and supplemented with salinomycin; ACTM50, advanced chelated trace minerals (ACTM) match to 50% of the ITM in the PC diet; and ACTM100, ACTM match to 100% of the ITM in the PC diet.
