Abstract

Selenium (Se), while not required by plants, is an essential trace element
for adequate nutrition and health for fish, birds, animals, and humans.
Generally, diets containing 0.1-0.3 mg/kg Se will provide adequate Se for
these various animals. However, many soils are incapable of providing
that amount to the plants growing on them. Animals consuming low-Se
diets will be Se-deficient, grow poorly, or even die. Conversely, there are
soils that provide an abundance of soluble Se. Some plants growing on
these Se-rich soils may accumulate Se in excess of the 3-15 mg/ kg concentration
at which animals begin to show Se toxicity symptoms. This
multifaceted characteristic of Se makes it imperative that scientists and
policy makers recognize the deficiency, adequacy, and toxicity effects of Se
on animal health. This chapter presents information about these aspects of
Se in the plant and animal system.
