Effect of C. perfringens challenge and dietary EA levels on serum inflammation biomarkers and plasma D-xylose concentration of broilers at d 42. (A, B, C, D and E) The concentrations of endotoxin lipopolysaccharide (LPS, EU/mL), interleukin 6 (IL-6, ng/L), C-reactive protein (CRP, mg/L), procalcitonin (PCT, ng/L), and the activity of myeloperoxidase (MPO, U/L) in serum. (F) Plasma D-xylose concentration (mmol/L). Unchallenged, birds without C. perfringens infection; challenged, birds with C. perfringens infection. Values are means (n = 6) with their standard errors represented by vertical bars. ^{a, b, c} Values with unlike letters were significantly different (P < 0.05). * Significant main effect (P < 0.05) of C. perfringens challenge
