Abstract: Epigenetic modifications are heritable changes in gene expression and phenotype without changing in the DNA sequence. Previous studies have shown that epigenetic regulation is involved in many life processes and plays an important role in fat deposition. Moreover, fat deposition is an important factor affecting the meat quality of livestock and poultry. Studying the mechanism of fat deposition is a significant aspect of breeding. In this review, the research progress of DNA methylation, mRNA modification, histone modification, chromosomal remodeling, and non-coding RNA regulation on the mechanism of fat deposition in livestock and poultry were summerized.

Key words: epigenetics, fat deposition, DNA methylation, mRNA modification, histone modification, non-coding RNA
