Summary
This study investigates the extent to which seasonal environmental variability — encompassing forage quality, soil nutrient status, and climatic conditions — affects the nutritional composition of eggs from hens managed under a regenerative, pasture-based system in Southern Ohio. By tracking egg nutrient profiles across the grazing season, the research provides empirical evidence relevant to both the nutritional claims associated with pasture-raised eggs and the broader resilience of pasture-based poultry systems. The findings are likely to contribute to understanding how production season mediates the nutritional advantages commonly attributed to pasture access in laying hens.
UK applicability
Although conducted in the United States, the findings are broadly applicable to UK pasture-based poultry systems, particularly given growing interest in regenerative and free-range egg production under UK and devolved agricultural policy frameworks. Seasonal variability in pasture composition is similarly pronounced in the UK, suggesting comparable fluctuations in egg nutrient profiles may occur in British systems.
Key measures
Egg nutrient composition including fatty acids (e.g. omega-3, omega-6), fat-soluble vitamins (e.g. vitamin D, vitamin E), carotenoids, minerals; forage quality; soil composition; seasonal climate variables
Outcomes reported
The study measured how seasonal changes in forage quality, soil composition, and climate influenced the nutrient profile of eggs produced under a regenerative pasture-based laying hen system in Southern Ohio. Likely outcomes include seasonal differences in fatty acid profiles, fat-soluble vitamins, carotenoids, and minerals across the grazing season.
