Symptoms of selenium deficiency are very uncommon in the adult horse. The only observable effect of mild deficiencies may be a decreased in an animal's ability to respond to infection. In the growing horse there may be a slowing of growth or stunting.
In the young foal, severe deficiencies may result in muscle disease or a necrotic fat disorder. These foals are weak, listless and stiff with a stilted hopping gait. The muscle degeneration can effect the heart to the point of creating a life threatening failure.
Selenium concentration in plasma is normally: 0.09 mg/L (ppm) to 0.3 mg/L. Values less than 0.05 are considered deficient. The Advisor Vet, RN Oglesby DVM
