Researchers from ILVO and Ghent University have explored the impact of microalgae in poultry feed. This review looks at the health effects on broilers and laying hens.
Microalgae, with their rich nutritional profile, are being studied as a feed additive. The bioactive substances they contain, such as phenolics, polyunsaturated fatty acids, oligosaccharides, and carotenoids, can support poultry health. These compounds offer benefits like antioxidant, anti-inflammatory, antibacterial, and antiviral properties.
With the ban on preventive antibiotic use in feed, microalgal biomass is seen as an alternative for enhancing growth and reducing health issues. The review covers key health areas including intestinal tract histology, permeability, immunity, antioxidant levels, and the effects on the intestinal microbiome.
The review concludes with recommendations for further research and practical steps to improve poultry health using microalgae.
