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… 
Effects of Dietary Conjugated Linoleic Acid and Selected Vegetable Oils or Vitamin E on Fatty Acid Composition of Hen Egg Yolks
Abstract The objective of this study was to produce eggs enriched with conjugated linoleic acid (CLA) and ameliorate their fatty acid profile using the appropriate combination of dietary CLA with or
Comparative analysis of fatty acid composition of yolk lipids in indigenous and conventional chicken eggs.
Eggs of the indigenous laying hens are preferred by consumers to those obtained from commercial breeds. The present study aimed to compare the fatty acid (FA) composition of yolk lipids of indigenous
Comparison of free-range, barn and caged hens’ eggs commercially available in Latvia
Consumers often consider free-range eggs to be superior to eggs from caged hens. The aim of the study was to identify whether different hen housing systems had an influence on egg quality in Latvia.
Comparison of fatty acid, cholesterol, vitamin A and E composition, and trans fats in eggs from brown and white egg strains that were molted or nonmolted.
TLDR
Strain and molt appear to influence nutrient composition and component percentages in eggs produced from laying hens with respect to egg color, hen strain, and molting.
Breed and feed affect amino acid contents of egg yolk and eggshell color in chickens.
TLDR
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.

Analysis of fatty acids in egg yolks of various production systems
TLDR
Egg yolk from organic hens with access to outdoor exercise yards appears to have a higher DHA content but this result need to be confirmed by fur-ther research.

Studies on the composition of food
TLDR
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.
Omega-3 enriched eggs: The influence of dietary α-linolenic fatty acid source on egg production and composition
TLDR
This study showed no advantages to replacing chia with flaxseed as a source of α-linolenic acid in laying hen feed and panel preferences were lower for eggs produced by hens fed the highest level of flax Seed (T2).
Vitamin Profiles of Eggs as Indicators of Nutritional Status in the Laying Hen: Diet to Egg Transfer and Commercial Flock Survey
TLDR
Diet to egg transfer of vitamins from previous experimental studies and whether dietary status for riboflavin, vitamin A, or vitamin B12 is a problem in commercial chicken laying flocks and breeding flocks is determined by measuring egg vitamin content.
The Effects of Nonstarch Polysaccharide Enzyme Addition and Dietary Energy Restriction on Performance and Carcass Quality of Organic Broiler Chickens
TLDR
During the spring months, NSP enzyme inclusion enhanced performance only when broilers were given access to pasture, and feeding a low-energy diet with NSP enzymes did not enable broilers to overcome a 7% energy dilution.
Vitamin profiles of eggs as indicators of nutritional status in the laying hen: riboflavin study.
TLDR
The results show that low albumen riboflavin content immediately affect hatchability and embryonic development and indicate that egg rib oflavin concentrations are related to important production parameters that may be used to predict future dietary ribOflavin inadequacies.
Dietary Amino Acid Density Effects on Growth and Carcass of Broilers Differing in Strain Cross and Sex
TLDR
Overall improvements in economically important parameters observed after feeding an amino acid concentration greater than that typically used by some broiler integrators in the US suggest that industry standard nutritional programs may be low in amino acids.
Studies on the composition of food
TLDR
It was concluded that bread made by the Chorleywood Process cannot be distinguished from conventional bread in its content of protein, fat, ash and nicotinic acid, and in protein quality as indicated by its net protein utilization value.
