Mean fold changes in cyclooxygenase-2 (COX-2), inducible nitric oxide synthase-1 (iNOS-1), and plasminogen activator inhibitor-1 (PAI-1) messenger RNA (mRNA) expression after oligofructose administration in heifers. Significant increases in inflammatory molecules relative to the control group are indicated as *P < 0.05, **P < 0.01.
