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.

Antimicrobial activity
Olive oil leaf extract has demonstrated strong antimicrobial activity against Campylobacter jejuni and Staphylococcus aureus (including methicillin-resistant S. aureus.
