Abstract
Selenium is an essential trace element that humans and animals must take into the body through food. The role of selenium in the body is multiple due to its participation in a number of biochemical processes. However, a very low level of selenium in the soil, and consequently in feed, may be the cause of selenium deficiency in animals and in humans. Selenium deficiency in animals can be manifested through many degenerative changes, pancreatic disease, worse reproductive and immune responses, and various muscular dystrophy, and in birds it causes exudative diathesis, poorer feathering, lower production, fertilization and hatchability of eggs, poorer quality of table eggs and the like. In addition to the deficiency, which is more common in animals, the surplus of this microelement may also occur. Long-term intake of high levels of selenium into body can cause poisoning. In poultry feeding selenium is added in two forms, inorganic or organic. It is scientifically proven that selenium absorption is much more effective if selenium is in organic form. Therefore it is recommended to add selenium yeast or, more recently, selenium fortified cereals in poultry feed. Various researches have proven that meat and eggs with higher selenium content represent a new potential source of this element in the human diet and can be offered as enriched products. The aim of this paper is to present the importance of selenium on production and egg quality, antioxidant activity and increase of selenium content in eggs.
