Low Selenium

Blood glutathione peroxidase (GSH-Px) activity in mountain goats (Oreamnos americanus) is a linear function of blood selenium. GSH-Px activity per unit of selenium (Se) in mountain goats is approximately double that published for the domestic cow and horse. It is hypothesized that high GSH-Px activity per unit selenium in mountain goats reduces their dietary selenium requirement relative to the above domestic species and is an essential adaptation for occupying low-selenium environments. GSH-Px activity peaked 20–30 days after injections of 0.1 and 0.3 mg Se/kg. A higher dose of 0.5 mg Se/kg delayed and decreased the development of peak GSH-Px activity relative to the two lower injection groups. When acute pathology owing to a selenium deficiency is demonstrated in wildlife capture programs, passive selenium supplementation, such as with selenium-containing salt blocks, should begin weeks to months before capture to provide adequate time for GSH-Px development.
