Abstract


The main biological role of selenium is performed via enzyme glutathione peroxidase, and includes the participation in the defense mechanism of the cell membrane from the peroxide damage. The aim of this study was to determine the effect of added selenium in foods in varying amounts and from various sources (organic and inorganic selenium). The experiment was conducted on the broilers, and the following parameters were monitored: body weight, total serum protein and the activity of the liver enzymes AST and ALT.
The study demonstrated that organically-bound selenium had the most pronounced protective property, while both forms of selenium did not significantly affect the growth and concentration of the total serum protein. Therefore, this research suggests economic benefits of organic selenium in the diet of broiler chickens.

Key words: selenium, body weight, liver function, broiler chickens
