  author={Uttam Kumar Saha and Abioye O. Fayiga and Dennis W. Hancock and Leticia S. Sonon},
Selenium (Se), an essential nutrient for animals and humans, occurs as selenoproteins in enzymes. It is very important in animal nutrition because it functions as an anti-oxidant assisted by vitamin E. Se deficiency is a major problem which can be reduced or prevented by supplementation with inorganic or organic sources of Se. However, excessive supplementation and consumption of Se accumulating plants may lead to Se toxicity and animal poisoning. Minimal lethal dose for animals range between 1… Expand

The role of selenium and vitamin E in a Transylvanian enzootic equine recurrent rhabdomyolysis syndrome.
Selenium deficiency possibly has a role in the Transylvanian enzootic equine recurrent rhabdomyolysis syndrome and horses in the affected regions had significantly lower serum selenium and GSH-Px levels than animals living in the non-affected regions. Expand


The efficacy of selenium treatment of forage for the correction of selenium deficiency in horses
Application of Se-enriched fertilizer increased the Se concentration of hay to a degree sufficient to meet the published dietary requirement for horses (0.1 mg/kg DM), and feeding of Se -enriched hay was an effective method of Se supplementation of horses. Expand
Selenium in Cattle: A Review
The impact and results of Se supplementation in cattle depend on physiological stage, Se status of animals, type and content of Se and types of Se administration and further studies in Se supplementation should investigate the speciation of Se in food and yeasts, as well as understanding their metabolism and absorption.
