Abstract:

Epigenetics means that there are heritable changes in gene expression while without a change in DNA sequence.In the recent years,the researches of epigenetic regulation on livestock field have developed rapidly.The main studied domestic animals include poultry,swine,bovine,sheep and goat,thus a new subject——livestock epigenetics is developing.Livestock epigenetics mainly uses various kinds of epigenetic modifications involved in DNA methylation,histone modification and non-coding RNAs regulation to study livestock growth and development,disease resistance,reproduction and economic traits,and so on.Here,we reviewed the mainly research fields and progress on livestock epigenetics,the trends of livestock epigenetics studies were also discussed to comprehensively understand the molecular basis of the complex traits formation of livestock and poultry,which greatly broadened the research and strategy to improve the economic traits of livestock and poultry.

Key words: livestock epigenetics; epigenetic modification; epigenetic research field; livestock
