The objective of this presentation is to address selenium metabolism, disease relationships, and nutritional assessment in small ruminants. Selenium has long been recognized for its toxicity potential, which has driven the regulations restricting dietary supplementation. Selenium deficiency diseases are prevalent in small ruminants raised in geographic regions where soil selenium is marginal to deficient. Toxicity disease most often results from inappropriate parenteral supplementation. Sheep, goats, and camelids respond similarly to selenium deficiency or toxicity diseases, though diagnostic criteria assessing selenium status differ.
