Selenium deficiency will readily occur in selenium-deficient areas. The deficiency can be linked to vitamin E deficiency. Equally, calves can be affected by vitamin E deficiency when selenium levels are normal. The deficiency is manifest as ‘white muscle disease’, which may give signs of muscular weakness or, if the heart is affected, sudden death. Treatment in the short term is with injections of selenium and vitamin E. In the long term, there are long-acting selenium injectable preparations.
