Role of organic Se in sustaining egg production in aged laying hens under heat stress

Abstract

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 generated, the hen's normal metabolism, physiology and production performance will be negatively affected (Fouad et al., 2016).
