Abstract: DNA methylation is the earliest epigenetic modified way that results in the silencing of gene expression,and it plays an important role in maintaining the normal cellfunction,genetic imprinting,embryonic development. Recent researches viewed that DNA methylation involvoed in regulation of gene expression associated with mammary gland growth and lactation.With the development of DNA methylation researches,more and more applications would be found on dairy production and genetic breeding.The author reviewed DNA methylatiion,mammary gland lactation related gene DNA methylation and the application of DNA methylation on the dairy cows.

Key words: dairy cows; lactation; epigenetic; DNA methylation
