Implication

Comparative analysis reveals varied physical and nutritional profiles across commercial egg production types, suggesting housing labels alone do not guarantee superior egg quality.

Key Points

To evaluate and compare the physical and chemical quality attributes of commercial table eggs produced under different hen housing systems, specialty diets, and native genotypes.
Analyzed commercially marketed eggs in Portugal from caged, barn, free-range, organic, native Portuguese breed, and n-3 polyunsaturated fatty acid (PUFA)-enriched production systems.
Assessed chemical and physical characteristics, including yolk color, Haugh units, albumen protein content, and fatty acid profiles.
Organic eggs exhibited lighter yolk color and lower albumen protein concentrations, but demonstrated higher Haugh units relative to caged eggs.
Caged hen eggs yielded higher albumen protein content alongside lower Haugh units compared to organic eggs.
Omega-3 PUFA-enriched eggs exhibited the highest n-3 PUFA concentrations and darker yolk coloration compared with all other production systems.
