Schematic diagram summarizing the mechanisms underlying the hepatoprotective and oviprotective effects of the combination of quercetin and vitamin E to promote follicle formation and attenuate oxidative stress, inflammation, and apoptosis in aging breeder hens. Supplementation of quercetin + vitamin E promotes the synthesis and expression of reproductive hormones and their receptors, and up-regulates the transcriptions related to vitellogenesis and lipogenesis via the liver–blood–ovary signal axis in aging breeder hens.
