A comparative study on egg cholesterol contents and eggshell protoporphyrin and biliverdin pigments of different poultry species

This study compared the cholesterol levels and shell pigments (protoporphyrin biliverdin) of chicken (conventional organic), quail, pheasant, goose eggs. The material for was (organic system - Lohmann Brown conventional HyLine Brown) eggs, quail (Coturnix coturnix japonica), (local), pheasant (Phasianus colchicus) eggs homogeneously selected with a subjective scoring. High-performance liquid chromatography photodiode array detection used to analyze samples (HPLC-PDA). There were no significant differences in yolk content between species. Based on mg/g yolk, different poultry species had comparable amounts cholesterol. Quail eggshells contained significantly more protoporphyrin (81.92 M/g) than (conventional-organic) (P<0.01), but less (10.73 other (P<0.01). Biliverdin found only (2.83 (1.02 It observed that white shelled detectable pigment.
