“…Algae in laying hen diets can also influence carotenoid content of egg yolks. Laying hens fed five diets based on rapeseed/corn oils with or without microalgae (Nannochloropsis oculata) produced eggs that vary in carotenoid content and fatty acid composition of egg yolk (Fredriksson, Elwinger, & Pickova, 2006;Gładkowski et al, 2011). The microalgae were added to the feed as a source of n-3 long-chain polyunsaturated fatty acids and carotenoids.…”

Hen egg is a unique and important carrier of lipid soluble bioactive carotenoids -lutein and zeaxanthin. Egg yolk carotenoid profile is largely dependent on hen's feed composition. Naturally, lutein and zeaxanthin are polar carotenoids primarily deposited in human retina and provide several protective functions, i.e. protect the macula from damage by blue light, improve visual acuity, and scavenge harmful reactive oxygen species. They have also been linked with reduced risk of agerelated macular degeneration and cataracts, cardiovascular diseases, Alzheimer's, and possibly different cancers. This review summarizes the latest data on content and composition of hen egg carotenoids, effect of processing, feeding systems, feed additives, bioavailability, and physiological effect of egg carotenoids on human health issues.Carotenoides de huevo de gallina (luteína y zeaxantina) e impactos nutricionales en la salud del ser humano: una revisión RESUMEN La yema de huevo es un importante y único portador de carotenoides bioactivos liposolubles: luteína y zeaxantina. El perfil de carotenoides de la yema de huevo depende notablemente de la composición alimentaria de la gallina. La luteína y la zeaxantina son carotenoides polares naturales depositados principalmente en la retina humana y que aportan diversas funciones protectoras, como por ejemplo la protección de la mácula del daño provocado por la luz azulada, la mejora de la agudeza visual y expulsan las especies dañinas reactivas al oxígeno. Estos también están relacionados con reducir el riesgo de degeneración macular producido por la edad y las cataratas, enfermedades cardiovasculares, Alzheimer, además de la posibilidad de diferentes tipos de cáncer. Este estudio resume los datos más recientes acerca del contenido y la composición de los carotenoides de la yema de huevo de gallina, el efecto del procesamiento, los sistemas de alimentación, los aditivos alimentarios, la biodisponibilidad y el efecto psicológico de los carotenoides del huevo en los problemas de salud de las personas.

The paper presents the analysis of the profile composition of fatty acids in the molecules of phosphatidylcholine and phosphatidylethanolamine, by using hydrophilic interaction liquid chromatography and gas chromatography coupled with mass spectrometry. The profiles of 15 phosphatidylcholine and 8 phosphatidylethanolamine species were analyzed with a newly developed hydrophilic interaction liquid chromatography (HILIC)-electrospray ionization (ESI)-tandem mass spectroscopy (MS/ MS) method, by using a new stationary bonded phase. The application of the new method in control and experimental groups of egg yolk revealed significant differences in the composition of phospholipid species containing mainly polyunsaturated fatty acids. Additionally, using GC-MS, the profile of fatty acids in four groups with different dietary supplementation of hens was analyzed and 20 fatty acids in egg yolks were determined. Monounsaturated fatty acids were found in higher amounts than saturated fatty acids and polyunsaturated fatty acids in egg yolks. Oleic acid (18:1) was the major monounsaturated fatty acid in egg yolk while palmitic acid (16:0) was the major saturated fatty acid. Linoleic acid (18:2), arachidonic acid (20:4), and docosahexaenoic acid (22:6) reached the highest levels among the polyunsaturated fatty acids.

“…It may be thus concluded that poultry reactions on phytoadditives are variable, and blood indices are the criteria of their usefulness in these birds feeding. The components of applied humic-plant preparations are used in poultry feeding (Dobrzański et al 2007, Eren et al 2008, Gładkowski et. al 2011, Bubel et al 2013a.…”

An influence of various humic-plant feed additives based on some herbs (nettle, chamomile, yarrow, perforatum), lucerne and humic materials on biochemical indices of Lohmann Brown (LB) layers blood plasma was estimated. Hens were housed in deep litter system, 20 birds in a group. Four groups were formed: control (C -standard feeding), and experimental, supplemented with preparations: E-1 herbal-humic, E-2 humic-herbal and E-3 -humic-lucerne. Hens were placed in the pens on the 16 th week of life, addition of preparations with standard food mixture started at the 22 nd wk and lasted until 66 th wk of life. Blood for analyses was collected four times in the following periods: 27, 37, 54 and 65 th wk of life. The applied humic-plant preparations to a limited degree affected the values of examined biochemical parameters in serum: total protein (TP), albumins (Albs), glucose (Glu), urea, triacylglycerols (TAG), total cholesterol (TCh), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP). It is difficult to determine based on these study, which preparation is one the most active biologically, however is seems that humic-lucerne preparation affected the examined blood parameters to the highest degree. The reference values ranges in hens blood serum LB hens were proposed for: TP (43-65 g/l), Albs (15-22 g/l), urea (0.5-1.2 mmol/l),
