Effect of one week of dexamethasone inclusion in the feed on serum FITC-d recovery from birds in experiment 2. The treated birds received dexamethasone from day-of-hatch to d7. Birds were gavaged with FITC-d (4.17 mg/kg) on d7, and blood samples were collected 1 h later. a,b Superscripts indicate significant differences at P < 0.05. FITC-d sera was diluted 1:4 in PBS onto black 96-well fluorescent plates and measured at 485 nm excitation and 528 nm emission. C2 = Control; DexF2 = Dexamethasone (0.57 ppm); Baytril inclusion = 5 mg/150 g; n = 20 birds/treatment; Data are expressed as mean ± standard error.
