“…Such activity is attributed to the presence of lutein and zeaxanthin. Supplementation of laying hens with TFE at concentrations greater than 1% increased the lutein content in yolk [34]. Furthermore, 250 mg/kg lutein was shown to reduce lipid peroxidation in chicken egg yolk [13], whereas mg/kg lutein increased liver SOD activity, although it did not influence liver lipid peroxidation [35].…”

“…Furthermore, 250 mg/kg lutein was shown to reduce lipid peroxidation in chicken egg yolk [13], whereas mg/kg lutein increased liver SOD activity, although it did not influence liver lipid peroxidation [35]. Despite these promising results, to date, no study has investigated the effect of TFE as a source of lutein on the antioxidant status of embryos; most studies have focused on the effects on performance, egg quality, yolk, and meat pigmentation [14,15,36], and lipid peroxidation in yolk [34], liver, and muscle [37].…”

The effects of Tagetes erecta flower extract (TFE) and increasing levels of vitamin E (VE) in the diet of Japanese quail breeders on progeny performance and oxidative status were studied. Methods: 480 Japanese quail breeders were distributed in a completely randomized design with five treatments and twelve replications of six females and two males each. A control diet (25 mg/kg VE) and four diets supplemented with TFE (3 g/kg) and VE (25, 100, 175, or 250 mg/kg) were used. Fresh yolk samples and the yolk sac and liver from embryos (11 and 15 days) and chicks (hatch and 3 days) were analysed. Data were subjected to ANOVA, a regression linear model, and contrast tests and the level of significance was set at p < 0.05. Results: TF and VE in the maternal diet improved the amount of alfa-tocopherol and total carotenoid content in the yolk. TFE + VE reduced lipid peroxidation and improved the oxidative status in the fresh yolk, in the embryo and chick yolk, and in the liver. Liver superoxide dismutase activity in hatched chicks increased linearly with the VE level and was not altered by TFE. Maternal diets did not influence progeny performance (1 to 28 days) or the relative expression of superoxide dismutase or glutathione peroxidase genes in the liver of chicks. Conclusions: TFE is an effective antioxidant in fresh eggs and supplementation of 3 g/kg TFE and high levels of VE in quail breeders improves the oxidative status of embryos and newly hatched chicks.

The research investigates the possibilities of enriching eggs with n-3 polyunsaturated fatty acids, selenium, vitamin E, and lutein. The research was carried out on 100 TETRA SL laying hens divided into two groups (C and E). Hens in treatment C (control group) were fed a standard feeding mixture that contained 5% soybean oil, 0.32 mg/kg organic selenium, 25.20 mg/kg vitamin E, and 20.5 mg/kg lutein (Marigold flower extract). Hens in treatment E (experimental group) were fed a mixture in which soybean oil was replaced by 1.5% fish oil + 1.5% rapeseed oil + 2.0% linseed oil. The content of other nutricines amounted to 0.47 mg/kg organic selenium, 125.2 mg/kg vitamin E, and 120.5 mg/kg lutein. Portions of total n-3 polyunsaturated fatty acids in enriched eggs were significantly increased when compared to conventional eggs (480.65: 204.58 mg/100 g; p < 0.001). The content of selenium, vitamin E, and lutein was significantly higher (p < 0.001) in enriched eggs than in conventional eggs. The content of selenium in egg albumen was increased by 1.81 times, and in the yolk, it was increased by 1.18 times. At the same time, the content of vitamin E was 2.74 times higher, and lutein was 8.94 times higher in enriched eggs than in conventional eggs.
