Selenium protective

In most diets used in livestock production, from 0.04 to 0,10 ppm of selenium protects the animal from deficiency diseases. If the diet is very high in vitamin E, the required level of selenium may be lower.

Selenium An element with the atomic symbol Se, atomic number 34, and atomic weight 78.96. It is an essential micronutrient for mammals and other animals but is toxic in large amounts. Selenium protects intracellular structures against oxidative damage. It is an essential component of glutathione peroxidase. [NIH]...

Hemolytic anemia of newborn infants—Newborn infants are more prone than other people to have abnormally shortlived red blood cells because blood levels of vitamin E— which together with selenium protects the membranes of red cells from premature disintegration are often subnormal at birth. Hence, it is suspected that selenium deficiency might tend to aggravate this condition, since the selenium enzyme glutathione peroxidase protects against this disorder. It is noteworthy, therefore, that cow s milk contains only half as much selenium as human milk, and that both types of milk are relatively poor sources of the mineral. 

Selenium protects against the toxic effects of arsenic, cadmium, copper, mercury, and silver. Likewise, these elements counteract the toxic effects of selenium.
