Abstract In the US farmers often market pastured poultry eggs for a premium price, claiming animal and human health benefits. We examined how moving pastured hens to forage legumes or mixed grasses influenced hen (Gallus gallus L.) egg omega-3 fatty acids and concentrations of vitamins A and E. We also compared the eggs of the pastured hens to those of hens fed a commercial diet in cages. We used a cross-over design to compare pasture species: 75 sister hens were assigned to one of three…

It is suggested that it is possible to produce designer eggs with enriched components, including yolk amino acids, by adjusting both genetic and environmental factors, which represents a first step in understanding the mechanisms underlying the production of value-added eggs in chickens.

Though the differences in vitamin B 12 and folic acid contents which result from the different systems of management are of little significance in an average mixed diet, they would be measurable for some individuals who may depend on eggs as an important source of these nutrients.
