Abstract Background Selenium Se is important for the postnatal development of the calf. In the first weeks of life milk is the only source of Se for the calf and insufficient level of Se in the milk may lead to Se deficiency. Maternal Se supplementation is used to prevent this. We investigated the effect of dietary Se-enriched yeast SY or sodium selenite SS supplements on selected blood parameters and on Se concentrations in the blood colostrum and milk of Se-deficient Charolais cows. Methods Cows in late pregnancy received a mineral premix with Se SS or SY 50 mg Se per kg premix
