Depletion of selenium in blood, liver and muscle from beef heifers previously fed forages containing high levels of selenium

Concentration of Se (mg/kg wet weight) in muscle tissue from beef heifers that had previously grazed creeping wildrye (CWR; solid line) or tall wheatgrass (TWG; dashed line) for 165 d and were fed a low Se diet for 209 d. Concentration of Se in muscle tissue remained higher in heifers that grazed TWG except at 209 d, compared to heifers that grazed CWR.87
