Propolis is a resinous hive product collected by honeybees from various sources of
plants. Numerous scientific investigations have been focused on the biological
activities of propolis and its functions as a health supplement in humans. It
could have similar function in other animals, such as in poultry. This review is
focused on the recent findings concerning the effects of propolis, as an antioxidant,
on performance, carcass characteristics, behaviour, immunity, and physiological
homeostasis in domesticated poultry species (broiler chickens, laying hens, quail,
and duck); and the needs in future poultry research.
