Marker-assisted selection (MAS) has emerged as a pivotal tool in enhancing livestock productivity and maintaining genetic diversity. This study analyzes the impact of MAS on livestock by integrating molecular markers with traditional breeding methods. This study highlights the efficiency of MAS in improving quantitative traits, disease resistance, and overall genetic diversity in livestock populations. The integration of genomic selection (GS) with MAS has further revolutionized animal breeding by enabling the identification and selection of superior traits with higher precision. Despite the challenges associated with complex traits and the need for large reference populations, MAS has shown significant promise in accelerating genetic gains and improving livestock productivity. Future directions include the adoption of high-throughput genotyping technologies and the development of more robust selection indices to enhance the efficiency of MAS in livestock breeding programs.
