ABSTRACT
This study aimed to investigate the effects of dietary selenium during pregnancy on the selenium deposition and antioxidant enzymes in postpartum mouse serum, liver, and mammary gland. Eighty BALB/c pregnant mice were randomly divided into four groups CG (Se-deficient basal diet, n = 20), LG (0.05 mg/kg Se-supplemented diet, n = 20), MG (0.1 mg/kg Se-supplemented diet, n = 20), and HG (0.2 mg/kg Se-supplemented diet, n = 20). Four days after parturition, all mice were euthanized. The selenium deposition and antioxidants enzymes in serum, liver, and mammary gland were detected. Results show that with increasing selenium supplementation, the selenium deposition and activation of T-AOC, T-SOD, and GSH-Px increased, meanwhile the concentration of MDA decreased in serum, liver, and mammary gland. Therefore, this study suggested selenium was mainly deposited in the liver, and dietary selenium during pregnancy might improve the antioxidant status in postpartum animals.
