This study evaluates the effects of dietary selenium (Se) sources—sodium selenite (SS), nano-selenium (Nano-Se), selenocysteine (Se-C), and selenomethionine (Se-Met)—on production performance, egg quality, preservation characteristics, yolk Se content, antioxidant capacity in Hy-Line Grey laying hens. A total 450 healthy 18-week-old hens were allocated to five groups (basal diet without Se, 0.30 mg/kg SS, Nano-Se, Se-C, or Se-Met) for an 8-week trial after a 4-week Se-depletion phase. The key results demonstrate that while no significant differences observed feed intake, rate, weight among (p > 0.05), organic (Se-C, Nano-Se significantly improved color < 0.05) index mitigated declines albumen height Haugh unit during storage. Notably, exhibited superior efficacy enhancing enzyme activity 0.05). Furthermore, increased deposition reduced lipid peroxidation These findings indicate supplementing 0.3 enhances extends shelf life, improves capacity, offering sustainable strategy selenium-enriched production.
