Effects of dietary supplementation with magnolia bark extract on antioxidant and detoxifying gene transcript levels in the spleen. Chickens were fed unsupplemented or magnolia extract–supplemented diets and were uninfected or co-infected with E. maxima and C. perfringens. The levels of transcripts for AFAR (A), CAT (B), HMOX1 (C), and SOD1 (D) in the spleen were measured at day 20. Values are means ± SEMs, n = 4. *Difference between chickens fed the magnolia extract–supplemented diet compared with unsupplemented controls, P < 0.05. **Difference between E. maxima/C. perfringens co-infected chickens compared with uninfected controls, P < 0.05. P values for the interaction between dietary magnolia extract supplementation and E. maxima/C. perfringens co-infection are listed below each panel. AFAR, aflatoxin B1 aldehyde reductase; CAT, catalase; HMOX1, heme oxygenase 1; M/H high, 0.56 mg M. officinalis bark extract/kg; M/H low, 0.33 mg M. officinalis bark extract/kg; NE, Necrotic enteritis; SOD1, superoxide dismutase 1.
