With the growth of global food demand, improving the egg production performance of poultry has become an important goal in animal husbandry and genetic research. This study comprehensively analyzed the application and achievements of whole genome association analysis (Genome-wide association study, GWAS) in revealing the genetic basis of poultry egg production performance, highlighting the important contribution of GWAS technology in identifying key genetic markers and associated regions that affect egg production performance. By reviewing and analyzing recent research cases, this study demonstrates how GWAS can help scientists gain a deeper understanding of the genetic mechanisms underlying poultry egg production performance and provide targeted strategies for genetic improvement in poultry. We also discussed the challenges faced by current methods, including the complexity of statistical correction, the interaction between genetic and environmental factors, and how to effectively apply GWAS findings to breeding practices. This study provides prospects for the future development of genetic research on poultry egg production performance, emphasizing the importance of integrating emerging genetic editing technologies, improving individual genome selection accuracy, and developing precision animal husbandry. It not only provides scientific basis for genetic improvement of poultry egg production performance, but also contributes new ideas to the sustainable development of animal husbandry.
