Reducing antibiotic growth promotors in animal feed calls for the development of new strategies to improve feed efficiency (FE) in poultry production systems. This represents unique opportunities to explore the biochemical and physiological sources of inter-animal variations associated with FE. Research has demonstrated a genetic link between higher feed efficiency and less mitochondrial ROS (reactive oxygen species) production at the cellular level in broilers.
More recent studies indicate a positive relationship between increased anti-oxidative capacity in broilers induced by certain plant extracts in feed and improved FE.
