| Abstract: | Selenium (Se) levels in whole blood and plasma, and glutathione peroxidase (GSH-Px) activities in red cells and plasma were
measured in ewes fed an Se-deficient diet injected with barium selenate before breeding season. Highly significant increases
in Se levels and GSH-Px activities (P<0.001) were observed throughout the gestation period and during lactation. In the control group, Se levels and GSH-Px activities
decreased significantly (P<0.001), and were at critically low levels during lambing and lactation periods. |
