n-3 PUFA Enriched Eggs as a Source of Valuable Bioactive Substances.

This research elaborates the process of enriching table eggs with n-3 polyunsaturated fatty acids (n-3 PUFA) and presents the effect of such enriched eggs on human health. The experiment was performed on 480 TETRA SL laying hens divided into three groups. Feeding mixtures contained 5% of oils (K = soybean oil, P1 = 3.

The Interaction between Feed Bioactive Compounds and Chicken Genome.

Consumer demand for high quality and safe foods that will have a positive impact on their health has increased in recent years. Today, it is possible to meet those demands by combining the genetic potential of domestic animals and applying different feeding strategies. Nutrigenomics is one of the "omics" sciences that studies the interaction between nutrients and the genome together with their influence on metabolic and physiological processes in the body.

Consumption of Nutritionally Enriched Hen Eggs Enhances Endothelium-Dependent Vasodilation via Cyclooxygenase Metabolites in Healthy Young People-A Randomized Study.

Objective: The present study aimed to evaluate the effects of enriched hen egg consumption on endothelium-dependent vasodilation (EDV) and the role of cyclooxygenases in EDV in the microcirculation of young healthy individuals. This study hypothesizes that Nutri4 eggs will improve endothelial function, which will be manifested by changes in microcirculatory flow measured by a laser Doppler flowmeter (LDF) during reactive hyperemia in response to vascular occlusion, in which -3 PUFA plays an important role as well as its degradation pathway by cyclooxygenases.

Materials And Methods: Participants consumed three eggs per day for three weeks: The control group (CTRL, = 14) consumed regular hen eggs (approximately 0.

Fatty acid profile of eggs produced by laying hens fed diets containing different shares of fish oil.

This paper presents the results of the research on the use of fish oil (FO) in combination with soybean oil (SO) in laying hens diet on physical and chemical properties of fresh eggs and those stored in a refrigerator for 28 d at + 4°C. Fatty acids (FA) profile, as well as thiobarbituric acid reactive substances (TBARS) values in yolks are also presented. The following feeding treatments have been used: C (control, without FO), E1 (0.

Carnosine, Small but Mighty-Prospect of Use as Functional Ingredient for Functional Food Formulation.

Carnosine is a dipeptide synthesized in the body from β-alanine and L-histidine. It is found in high concentrations in the brain, muscle, and gastrointestinal tissues of humans and is present in all vertebrates. Carnosine has a number of beneficial antioxidant properties.

The effect of n-3 polyunsaturated fatty acids-enriched hen eggs consumption on IgG and total plasma protein N-glycosylation in healthy individuals and cardiovascular patients.

This study determined the effect of n-3 polyunsaturated fatty acids (n-3 PUFAs)-enriched hen eggs consumption on immunoglobulin G (IgG) and total plasma protein N-glycan profiles and inflammatory biomarkers level in healthy individuals (N = 33) and cardiovascular (CV) patients (N = 21). Subjects were divided to Control-Healthy and Control-CV subgroups [consumed three regular hens' eggs/daily (249 mg n-3 PUFAs/day)], and n-3 PUFAs-Healthy and n-3 PUFAs-CV subgroups [consumed three n-3 PUFAs-enriched hen eggs/daily (1053 mg n-3 PUFAs/day)] for 3 weeks. Serum-free fatty acids profile and high-sensitivity C-reactive protein, interleukin 6 and 10 (IL-6, IL-10) and tumor necrosis factor alpha were measured.

Anti-Inflammatory Potential of n-3 Polyunsaturated Fatty Acids Enriched Hen Eggs Consumption in Improving Microvascular Endothelial Function of Healthy Individuals-Clinical Trial.

The effects of consumption of n-3 polyunsaturated fatty acids (n-3 PUFAs) enriched hen eggs on endothelium-dependent and endothelium-independent vasodilation in microcirculation, and on endothelial activation and inflammation were determined in young healthy individuals. Control group ( = 21) ate three regular hen eggs/daily (249 mg n-3 PUFAs/day), and n-3 PUFAs group ( = 19) ate three n-3 PUFAs enriched hen eggs/daily (1053 g n-3 PUFAs/day) for 3 weeks. Skin microvascular blood flow in response to iontophoresis of acetylcholine (AChID; endothelium-dependent) and sodium nitroprusside (SNPID; endothelium-independent) was assessed by laser Doppler flowmetry.

Microalgae Schizochytrium limacinum as an alternative to fish oil in enriching table eggs with n-3 polyunsaturated fatty acids.

Background: The research deals with the addition of microalgae Schizochytrium limacinum as an alternative to fish oil in a feed-mixture for laying-hens and its effect on the deposition of n-3 polyunsaturated fatty acids (n-3-PUFAs) [α-linoleic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)] in the lipids of egg yolks. In the study, 240 Tetra SL laying hens housed in enriched cages were used, divided into six groups, each in five repetitions. Groups E1, E3 and E5 were given 0.

Quality and oxidative stability of eggs laid by hens fed marigold extract supplemented diet.

The research objective was to determine the influence of marigold extract and storage duration on the indicators of egg quality and on the oxidative stability of eggs. The 5-wk long research was carried out on 300 laying hens. Laying hens were divided into control group (C-without marigold extract supplementation) and 2 experimental groups (E1-supplemented 1 g/kg of marigold extract and E2-supplemented 2 g/kg of marigold extract to diet).

Omega-3 polyunsaturated fatty acids-enriched hen eggs consumption enhances microvascular reactivity in young healthy individuals.

The beneficial effect of omega-3 polyunsaturated fatty acids (PUFA) supplementation on the cardiovascular (CV) system is well supported in CV patients; however, the effect of the consumption of omega-3 PUFA-enriched functional food in healthy individuals is still not fully elucidated. This study aimed to determine the effect of the consumption of omega-3 PUFA-enriched hen eggs on the microvascular reactivity (primary outcome), blood pressure (BP), and serum lipid profile in young healthy individuals. The control group (N = 16) ate 3 ordinary hen eggs (277 mg of omega-3 PUFAs/day), and the OMEGA-3 group (N = 20) ate 3 omega-3 PUFA-enriched eggs containing 259 mg of omega-3 PUFAs/egg daily (α-linolenic acid (ALA), 167 mg/egg; eicosapentaenoic acid (EPA), 7 mg/egg; docosahexaenoic acid (DHA), 84 mg/egg) for 3 weeks (777 mg of omega-3 PUFA/day).

The aim of this research was to investigate the deposition of carnosine in broiler muscles by feeding treatments comprising -alanine, L-histidine, and magnesium oxide in various concentrations. The research was carried out on 120 Cobb 500 broilers divided into four groups. From weeks four to six, broilers were fed finisher mixtures as follows: P1, control group; P2, 0.

Determination of anti-oxidative histidine dipeptides in poultry by microchip capillary electrophoresis with contactless conductivity detection.

A home-made microchip electrophoresis (MCE) device was used to quantitate two biologically important histidine dipeptides, carnosine and anserine, using capacitively coupled contactless conductivity detection (CD), at pH 2.7. The CD detector exhibited a linear response to both carnosine and anserine in the range of 0-200μM for the individual dipeptides and in the range of 0-100μM for each dipeptide when both were present as a mixture.

Poultry products enriched with nutricines have beneficial effects on human health.

The paper presents nutritive value of broiler meat and table eggs, as these animal products are used for human nutrition on a daily basis. In the Republic of Croatia, average consumption of poultry meat amounts to 18.3 kg and to 160 eggs per capita.

Heavy metal concentration in fish tissues inhabiting waters of "Busko Blato" reservoir (Bosnia and Herzegovina).

Heavy metals concentration (mercury, lead, cadmium, arsenic, copper, zinc and chromium) in tissues (muscles, liver, kidney and gonads) of Dalmatian barbelgudgeon, the nase, the souffie and brown trout, inhabiting waters of Busko Blato reservoir in Bosnia and Herzegovina, has been determined by atomic absorption spectrophotometry. The meat of the tested fish sorts does not contain elevated concentration of most analyzed heavy metals with exception of lead (higher than MAC in Italy, Germany and Denmark) and mercury (in muscles of brown trout higher than MAC in most countries). The lowest level of all heavy metals is always detected in gonads, with higher values in fry compared to milt for copper, zinc, chromium and arsenic.
