Oral mineral boluses are one choice of supplementation. The objective of this research was to find out the time and intensity of Se liberation from mineral intraruminal boluses measured by blood and wool Se concentration in female lambs for a 3 month period. Three groups of ten lambs each were formed for Se bolus administration. Orally administered boluses for these lambs were made with: 1%, 4.6% and without Se (ten boluses per group and a 5 g weight bolus per lamb). Lambs were grassing Lolium perenne, Pennisetum clandestinum and Trifolium repens latum, during the daytime , and received 250 g of a concentrated feed at the manger with no Se added. Mean blood and wool Se concentrations were 182.0 ng/g and 341.7 ng/g, respectively in the group with 4.6% Se boluses during the 3 month period. Statistical difference (P > 0.05) was higher when comparing two groups with 1.5% and no Se boluses. There was a statistical difference (P>0.05) when results of groups with 1% Se and the control one to group 4.6% Se were compared. Statistical difference in Se concentration between the control and the 1% Se bolus groups was not meaningful regarding blood, only in the wool one. It is concluded that mineral boluses with 4.6% Se content and 5 g weight are recommended as supplementation for grassing lambs.
