Chlorella (Chlorella vulgaris), also referred to as Chlorella microalgae, is a type of freshwater algae that is known for being a vegan source of both iron and bioavailable vitamin B12. Specific applications in relation to poultry include:
  • Heat Stress: A study was conducted on 378 laying hens to investigate the effect of different supplementation levels of Chlorella microalgae had on birds, when reared under heat stress conditions. Results showed that supplementing the hens' diet with 200-500 ppm C. microalgae was beneficial for the health.
  • Antitumor:
    A 2001 study from Brazil showed that an extract of chlorella prolonged the survival of mice that were injected with tumor cells.
  • Improve digestion: Feeding C. vulgaris in laying hens resulted in increased lactobacilli diversity in crop and increased bacterial community diversity in the ceca.
