Role of organic Se in sustaining egg production in aged laying hens under heat stress
Under heat-stress conditions (i.e. high temperature and humidity) and as the hen ages, oxidative stress increases due to the synthesis of reactive oxygen species (ROS). When the hen is unable to neutralize the various ROS molecules that are ...

Revisiting oxidative stress and the use of organic selenium in dairy cow nutrition
Among feed-derived antioxidants, selenium (Se) was shown to have a special place as an essential part of 25 selenoproteins identified in animals. Organic Se, in the form of selenomethionine (SeMet), has been reported to be a much more effec ...
