摘　　要：[Objective] To observe differences in egg quality between Shandong local hens and Hyline brown hens. [Method] Hyline brown hens and three Shandong local chicken breeds including Jining Bairi chicken, Wenshang Luhua chicken and Laiwu black chicken were selected for egg quality comparison. [ Result] The pementage of yolk, egg-shape index and shell strength were significantly higher in the Shandong local hens than in Hyline brown hens ( P 〈 0.05), but the opposite results were found for average egg size and Haugh unit ( P 〈 0.05). The contents of essential amino acids and linoleic acid were significantly higher in the Shandong local hens than in Hyline brown hens (P 〈 0.05), but no significant differ- ence in VA content, VE content, total amino acid content and fatty acid content was found between the Shandong local hens than in Hyline brown hens. [ Conclustion] The study investigated the effects of chicken breeds on egg quality, which provides a reference for improvement of chicken breeds in future.[Objective] To observe differences in egg quality between Shandong local hens and Hyline brown hens.
