Selenium supplementation of grazing sheep. I. Effects of selenium drenching and other factors on plasma and erythrocyte glutathione peroxidase activities and blood selenium concentrations of lambs and ewes



Selenium supplementation of grazing sheep. I. Effects of selenium drenching and other factors on plasma and erythrocyte glutathione peroxidase activities and blood selenium concentrations of lambs and ewes



Australian Journal of Agricultural Research 31(5): 991-1004



Lambs and ewes grazing in a selenium deficient area of New England were given a Se supplement. When lambs were drenched with Se at 14 days of age there were large and rapid increases in the initially low levels of plasma and erythrocyte glutathione peroxidase (GSH-px). The increase in plasma GSH-px was transitory, and a second drench given to half the treated lambs at 42 days did not evoke any further increase.
