Enrichment diets high in ground flax may cause irritation to the gut, which may affect absorption of omega-3 polyunsaturated fatty acids (ω-3 PUFA) from flax as well as other dietary enrichment ingredients. This study assessed the egg enrichment with ω-3 PUFA and Lutein when provided alone in the diet, in combination, or when fed in alternate day patterns. A total of 144 individually caged Lohm...
Oxidative stress experienced during early development can negatively affect diverse life-history traits, and organisms have evolved complex defence systems against its detrimental effects. Bird eggs contain maternally derived exogenous antioxidants that play a major role in embryo protection from oxidative damage, including the negative effects on telomere dynamics. In this study on the yellow-...
ISA Brown hens were fed diets supplemented with the synthetic carotenoids Carophyll Red and Carophyll Yellow at 20 and 15 mg/kg, respectively, lutein at 250 mg/kg, and the algae Chlorella at 12.5 g/kg. The synthetic carotenoids, lutein, and Chlorella significantly increased egg weight (P < 0.001), shell weight (P < 0.001), and thickness (P = 0.017) and decreased the yolk/albumen ratio (P = 0.03...
Wang Q., Jin G., Wang N., Guo X., Jin Y., Ma M. (2017): Lipolysis and oxidation of lipids during egg storage at different temperatures. Czech J. Food Sci., 35: 229–235. The aim of this study was to investigate lipolysis and lipid oxidation of stored eggs at different temperatures (4 and 22°C) by evaluating the changes in physicochemical index, lipid profiles, enzymatic activity, and oxidative i...
Immune defense involves inflammatory reactions in which immune cells produce reactive oxygen species (ROS) to fight pathogens. ROS may however cause damage to the host if they are not balanced by antioxidant defenses. Therefore, one should expect individuals undergoing an immune reaction to use antioxidants to prevent oxidative stress. Antioxidants are vital compounds that provide important pro...
the oxidative stability of margarine supplemented with different concentrations of fennel (foeniculum vulgare) seed extract (fse) was compared to the synthetic antioxidants; butylated hydroxyanisole (bha) and butylated hydroxytoluene (bht) at legal concentrations. the experiment was carried out under accelerated storage conditions for 4 weeks employing peroxide value (pv), p-anisidine value (av...
A mixture of three dietary medicinal herb extracts (MHE, mulberry leaf:Japanese honeysuckle:goldthread = 48.5: 48.5:3.0) was prepared as an additive of hen’s feed. One hundred-eight, 28-wk-old Lohmann Brown hens were assigned randomly with three levels of MHE in the diet (0, 0.3, and 1%). Hens were fed for 6 wks and eggs were collected in the 6th week, and stored at 4°C for 14 days to investiga...
Elevated levels of maternal androgens in avian eggs affect numerous traits, including oxidative stress. However, current studies disagree as to whether prenatal androgen exposure enhances or ameliorates oxidative stress. Here, we tested how prenatal testosterone exposure affects oxidative stress in female domestic chickens (Gallus gallus) during the known oxidative challenge of an acute stresso...
BACKGROUND We have previously characterized several antihypertensive peptides in simulated digests of cooked eggs and showed blood pressure lowering property of fried whole egg digest. However, the long-term effects of this hydrolysate and its fractions on blood pressure are not known. Therefore, the objectives of the study were to determine the effects of long term administration of fried whol...
Activator protein-1 (AP-1) transcription factor DNA binding is induced during transient oxidative stress in the midorganogenesis rat conceptus in culture. L-2-Oxothiazolidine-4-carboxylate (OTC), a cysteine prodrug, prevented oxidative stress and the induction of AP-1 binding activity in the embryo but not in the yolk sac. Because AP-1 activity may be a significant determinant of developmental ...
