Concentrations of Pp IX in liver and the mucosal layer of shell glands of hens with different eggshell colors. A Pp IX concentrations in the liver and the mucosal layer of shell gland at 4H, 16H and 22H in the DBS group. B Pp IX concentrations in the liver and the mucosal layer of shell gland at 4H, 16H and 22H in the LBS group. C Pp IX concentrations in the mucosal layer of shell gland of the WS, LBS and DBS groups at 4H, 16H and 22H. D Pp IX concentrations in the liver of the WS, LBS and DBS groups at 4H, 16H and 22H. Data expressed as mean ± SD. **P < 0.01, *P < 0.05
