Figure 4

Protein levels of inflammatory cytokines in serum at d0, d7, and d14. Values are least square means (n = 6) and SEM represented by vertical bars. Within a time-point (d0, d7, or d14) columns with symbols are different: * = P < 0.05; ** = P < 0.01. Data refer to picograms of cytokine per milliliter of serum (pg/ml) measured using ELISA method. Control = basal diet; OA + PB = basal diet + mixture of organic acids and pure botanicals at 5 g/kg.
