Abstract: Crossbred beef cows (30) were split into two groups, with half receiving injectable selenium and half serving as the control. The injectable selenium was Deposel multidose. This is a slow realease barium selenate product. Blood was collected four times during the year, with cows receiving the Deposel having higher (P<0.01) serum selenium. Animals receiving the selenium also had higher (P<0.01) liver selenium than controls. Calves from cows receiving the injectable selenium also had higher (P<0.01) serum selenium than controls. During the one year trial barium selenate was effective for elevating selenium status of cattle.
