摘要：

Changes in blood and milk selenium (Se) concentrations were measured in dairy cattle grazing Se-deficient pastures compared with animals grazing the same pasture but given either an intraruminal Se bolus or a barium selenate injection. The Se supplementation significantly increased and maintained the blood Se concentrations (e.g., 342 versus 1113 nmol/l) over 190-265 days during the lactation and also increased milk Se concentrations 2-fold (e.g., 77.2 versus 132.3 nmol/l).
