The objective of this study was to investigate the relationship between total blood selenium concentration and liver tissue selenium concentration in cattle. Blood and liver samples were collected from 205 individuals brought to slaughter houses. The results had shown that there is a linear correlation between the concentration of selenium in total blood of cattle (X) and its concentration in the liver (Y). The linear regression equation was: Y=0.194+3.951± (0.265***) X (0.009 μg/ml ? X ? 0.219 μg/ml, 0.110 μg/g DM ? Y ? 1.512 μg/g DM) (r2=0.523, ***P<0.001, n=205).
