Abstract: Skeletal muscle, the most abundant tissue in animals, directly influences meat production performance, making it one of the most important production traits during animal growth and development. In recent years, DNA methylation has been widely applied in research on muscle growth and development in livestock. The role of DNA methylation in the regulation of porcine skeletal muscle growth and development was reviewed, with the hope to provide a reference for the genetic improvement of pigs.

Key words: DNA methylation; pig; skeletal muscle; development regulation
