This study reviews the application of whole-genome association analysis in revealing genetic factors affecting livestock production traits. With the continuous development of biotechnology and genomics, whole-genome association analysis has gradually received attention as a powerful genetic research tool. This method detects associations between a large number of genetic markers and traits of interest, revealing the genetic basis of livestock production traits and providing a scientific basis for breeding and genetic improvement. This study first introduces the definition and classification of livestock production traits, as well as their genetic background and influencing factors. Next, an overview of the principles and methods of whole-genome association analysis is provided, along with a comparison of the advantages and disadvantages of traditional genetic research methods and whole-genome association analysis. Subsequently, through typical case analysis, the application and technological progress of whole-genome association analysis in the study of livestock production traits are elaborated in detail. Further discussion includes key genes and genetic markers identified through this method, as well as their practical applications in livestock genetic improvement. Finally, the importance of whole-genome association analysis in deciphering the genetic basis of livestock production traits is summarized, and the potential application value of it in the sustainable development of animal husbandry is discussed.
