GPX activities in muscle (A) and liver (B), FASN activities in muscle (C) and liver (D), and PEPCK activities in liver (E) of pigs fed 0.3 or 3.0 mg Se/kg for 11 wk (Expt. 2). The GPX activity unit is defined as 1 μmol NAD(P)H used/min. The FASN activity unit is defined as 1 mmol NAD(P)H used/min. Values are means ± SEs, n = 6. *Different from control, P < 0.05. Control = 0.3 mg Se/kg; high Se = 3.0 mg Se/kg. FASN, fatty acid synthase; GPX, glutathione peroxidase; PEPCK, phosphoenolpyruvate carboxykinase.
