Effects of dietary TFRD on RUNX2, OPG, and RANKL mRNA expressions in caged laying hens. Values are means ± SEM (n = 6 per group). The a, b, and c means every bars without same letter differ significantly (P < 0.05). Abbreviations: TFRD, total flavonoids from Rhizoma Drynariae; RUNX2, runt-related transcription factor 2; OPG, TNF receptor super family member 11b; RANKL, tumor necrosis factor super family member 11; CON, basal diet; TFRD1, basal diet supplemented with 0.5 g/kg TFRD; TFRD2, basal diet supplemented with 2.0 g/kg TFRD.
