Abstract

In dairy cows, several studies have mentioned that selenium (Se) improves immune function mainly through antioxidant enzymes that likely protect immune cells from oxygen-derived radicals. However, in beef cattle few studies have been conducted to evaluate the effect of Se on the immune system. The aims of this study were to determine the effects of source (organic or inorganic) Se supplementation on Se and glutathione peroxidase (GSH-Px) concentrations in beef cows and their calves and on immune variables of the calves.
