Comparison of the Metabolic and Flavor Characteristics of the Egg Yolks of BIAN Chicken and Hy-Line Brown Chicken Using LC-MS and GC × GC-TOF MS Techniques

This study elucidates the molecular basis of distinctive egg quality characteristics in local chicken breeds, offering a scientific rationale for the conservation and utilization of indigenous breeds and the documentation of their unique metabolic and sensory properties. Furthermore, it furnishes a theoretical framework for understanding breed-specific flavor development and provides baseline data for future genetic selection and nutritional intervention strategies.
