Abstract: Selenium is an essential mineral in animal nutrition, playing a key role in promoting health and productivity. This trace element is involved in bone formation, maintenance of the immune system, and regulation of enzymes and hormones. Adequate selenium supplementation can significantly improve reproductive performance, meat quality, and disease resistance. In ruminants, selenium is absorbed predominantly in the small intestine, with lower efficiency compared to non-ruminants due to the chemical environment of the rumen. In non-ruminants, such as pigs and poultry, absorption occurs directly in the small intestine, with selenomethionine being more efficiently absorbed. Selenium is transported and distributed throughout the body linked to proteins such as selenoprotein P and glutathione peroxidase, which are essential for cell protection against oxidative stress. Selenium deficiency can cause myopathy, reproductive problems, and reduced immunity in ruminants and non-ruminants. Selenium intoxication, on the other hand, can lead to liver and kidney damage, reproductive problems, and death. In conclusion, balanced management of selenium supplementation is fundamental to guaranteeing the health and productivity of animals, preventing both deficiencies and intoxications.
