Dr Barry Patten B.V.Sc., PhD. Selenium is an essential trace mineral in sheep and cattle (Barragry 1994). Oral selenium is absorbed mainly from the duodenum, absorbed selenium is carried in the plasma and undergoes a transformation in erythrocytes (Barragry 1994).elenium Intra-ruminal Pellets for Sheep and Cattle. A heavy pellet containing selenium was developed by CSIRO in 1967 by Kunckel and Buckley (CSIRO Rural Research 86; 19). The most effective pellet for sheep contained 5% elemental selenium (Kunckel and Buckley 1969).
