¹Values are means ± SEs, n = 3–6. Means with * are different from the controls, P < 0.05. GPX3, plasma glutathione peroxidase; LDH, lactate dehydrogenase; NBS, nonprotein-bound Se; PBS, protein-bound Se; Sepp1, selenoprotein P.

²In Expt. 1, the control diet contained 0.02 mg Se/kg; in Expt. 2, the control diet was supplemented with 0.3 mg Se/kg.

³In Expt. 1, the biofortified diet was supplemented with 3.0 mg Se/kg as sodium selenite; in Expt. 2, the biofortified diet was supplemented with 1.0 mg Se/kg as Se-enriched yeast.

⁴Values are relative density from the protein band.
