1. The effects of various sources of natural carotenoids (Px alfalfa concentrate, tomato powder and marigold extract) as feed additives in quail diets on egg yolk pigmentation and carotenoid composition were investigated. 2. Adult Japanese quail were fed one of 5 different diets for 23 d: three diets each contained Px alfalfa concentrate (PX) or tomato powder (TP) or marigold extract (MG), one diet contained marigold extract and tomato powder (MG + TP) and a control diet (wheat/barley based… 
Plant Carotenoids as Pigment Sources in Laying Hen Diets: Effect on Yolk Color, Carotenoid Content, Oxidative Stability and Sensory Properties of Eggs
The supplementation of plants in a hen diet may result in yolks containing carotenoid content, iron-induced oxidative stability, and other compounds showing a high antioxidant effect.
Increase in lutein and zeaxanthin content in the eggs of hens fed marigold flower extract.
Marigold flower extract is a suitable natural alternative for increasing the xanthophyll contents in eggs compared with the commercially used synthetic carotenoids.
Tomato powder in laying hen diets: effects on concentrations of yolk carotenoids and lipid peroxidation
Tomato powder supplementation increased egg production persistency and increased carotenoids and vitamin A contents in egg yolk, accompanied by reduced yolk lipid peroxidation.
Sano (Sesbania javanica Miq.) Flower as a Pigment Source in Egg Yolk of Laying Hens
Sano flower that naturally contains high concentration of yellow fat soluble pigment as a pigment source for egg yolk in layer diet has beneficial effect for enhancing yolk color, and adding 10 mg/kg of total carotenoids from Sano in carotENoids-free diet or in combination with cantaxanthin can elevate approximately one unit of Roche’s color fan scale.
The effects of carotenoids in quail breeder diets on egg yolk pigmentation and breeder performance
ABSTRACT The effects of supplementation of 10 mg/kg (i) apoester, (ii) canthaxanthin, (iii) 3% clover extract, (iv) paprika oleoresin and (v) aztec marigold extract pigments to a wheat-based
Natural sources of β-carotene and lycopene in laying hens' nutrition.
Egg morphological characteristics under influence of natural products VITATON and TOMATO OIL and Ca and P in the egg shell (mixed samples) were determined at the beginning and at the end of the trial and the yolk pigmentation obtained in experimental groups was more intensive.
Effects of dietary marigold extract supplementation on growth performance, pigmentation, antioxidant capacity and meat quality in broiler chickens
Dietary supplementation of marigold extract significantly increased the yellowness values of carcass, antioxidant capacity and meat quality in broiler chickens and no significant effect on growth performance was found.
The Effect of Red Pepper (Capsicum annuum) and Marigold Flower (Tageteserectus) Powder on Egg Production, Egg Yolk Color and Some Blood Metabolites of Laying Hens
There were no significant differences among treatments for egg quality traits but the yolk color changed in treated group compared with controls, and the white blood cell counts and some blood metabolites were measured.
Retention of carotenoids in egg yolks of laying hens supplemented with heterotrophic Chlorella.
The present study investigated the effect of 1 and 2% feed supplementation with biomass of Chlorella grown through heterotrophic fermentation on the concentration of total and individual carotenoids in egg yolks and found no differences among laying hens in plasma concentrations of triacylglycerol and cholesterol.


Use of Lycopene, an Antioxidant Carotinoid, in Laying Hens for Egg Yolk Pigmentation
The possibility of lycopene affecting egg yolk pigmentation was studied with lycopene diets containing 0, 4, 8, and 12 µg/g meal, respectively. The addition of lycopene above 4 µg/g meal
Patterns of yolk enrichment with dietary carotenoids in gulls: the roles of pigment acquisition and utilization
The results suggest that yolk enrichment with carotenoids involves physiological discrimination in gulls, highlighting a previously unstudied, potential cost of reproduction.
Enrichment of eggs with lutein.
Yolk lutein content can be increased, although further studies are needed to investigate the major decline in transfer efficiency seen with higher levels of dietary supplementation.
Tissue-specific distribution of carotenoids and vitamin E in tissues of newly hatched chicks from various avian species.
Carotenoid discrimination by the avian embryo: a lesson from wild birds.
Incorporation of lycopene in egg yolk.
Analysis of induced fluctuations in pigment contents of egg yolk were considered as a possible step towards an understanding of its mechanisms and lycopene was chosen a suitable marker because it has a characteristic absorption spectrum that permits its determination in the presence of the remaining pigments.
The role of carotenoids in human health.

Until the efficacy and safety of taking supplements containing these nutrients can be determined, current dietary recommendations of diets high in fruits and vegetables are advised.
