The objective of this study was to determine the effect of selenium (Se) from selenized yeast fed to lambs on their blood parameters, the activity of creatine kinase (CK), lactate dehydrogenase (LDH) in serum and Se in plasma. Lambs (n = 10) were randomly assigned to receive a basic diet (BD) providing a daily intake 50.6 micro g of Se only or supplemented to provide 0.3 mg/kg DM Se from the selenized yeast and giving a total daily intake 278 micro g of Se per animal. Lambs which were fed additional Se had an increased (P ,; 0.001) concentration of Se in plasma and greater activity of creatine kinase (CK) (P ,; 0.05) in their serum. Oral administration of Se brought an increase in erythrocyte count and in the osmotic resistance of red blood cells (P < 0.01). The total leukocyte count (TLC) was increased in lambs given BD (P < 0.05). Selenium supplementation brought about increased cell membrane resistance and increased selenium in plasma.
