Olives are small fruits produced by the olive tree (Olea europaea), a deciduous tree or shrub that is native to the Mediterranean region. Olive trees, and their various parts, have been used in traditional and contemporary medicine for a wide range of ailments. Specific applications relating to poultry include:
  • Cardiovascular Support: A study conducted in 2012 on the effects of supplementing broiler chickens' diets with 10 g/kg of dietary olive leaves, showed that it had an anti-hypertensive effect and decreased incidences of ascites in chickens exposed to cold ambient temperatures.
  • Egg quality: Adding 1-3% olive leaf powder to the diet of 120 laying hens for 8 weeks showed that it helped to reduce egg yolk cholesterol content and egg yolk coloring agent.
