In this study, we evaluated the enrichment efficiency of lutein in eggs and its function preventing fatty liver hemorrhagic syndrome (FLHS) aged laying hens. Five groups hens (65 weeks old) were fed basal diets supplemented with 0, 30, 60, 90, or 120 mg/kg lutein. The supplementation period lasted 12 followed by 2 depletion feed. results revealed that efficiently enriched egg yolks improved their color a significant increase relative redness (P < 0.001). Lutein accumulation increased yolk until day 10, then reached minimum level after 14 days. Overall, zeaxanthin content all was similar throughout experimental period. However, triglycerides total cholesterol significantly decreased 0.05) but not different serum > 0.05). serum, lipid metabolism enzyme acetyl-CoA synthetase reduced 0.05), whereas dipeptidyl-peptidase 4 there no statistical difference either Regarding oxidation inflammation-related indexes, malondialdehyde, tumor necrosis factors alpha, interleukin-6, interleukin-1 beta decreased, superoxide dismutase antioxidant capacity for same indexes limited. It concluded old to improve highest on 10 without being subject conversion into zeaxanthin. At time, prevented steatosis exerting strong anti-inflammatory functions, also through modulation metabolism, which may contribute reducing incidence FLHS poultry.
