Summary

Scientists tested a new kind of selenium in chicken food to see if it makes eggs healthier and more nutritious.

Proposed Mechanism
Selenized glucose enhances glutathione peroxidase activity via improved selenium bioavailability
Verified
Selenium reduces lipid peroxidation in egg yolk via GSH-Px-mediated antioxidant defense
Verified
Selenium improves eggshell quality by enhancing mineralization via antioxidant-mediated protection of shell matrix proteins
Supported by evidence
Selenium modulates gut microbiota by reducing oxidative stress and promoting lactic acid bacteria growth
Supported by evidence
Selenium enhances humoral immunity by supporting antibody production via GSH-Px-mediated lymphocyte protection
Supported by evidence
Selenium improves yolk color by protecting xanthophyll pigments from oxidative degradation
Supported by evidence
Selenium improves n-6/n-3 fatty acid ratio by reducing peroxidation of polyunsaturated fatty acids and modulating prostaglandin metabolism
