Abstract: Lipids are a kind of substance which can store and provide energy for animals. A large number of studies have confirmed that the change of lipids in diets can alter the expression of microRNAs (miRNAs) and thus affect the biological activities of the bodies. This review mainly summarizes the regulation of fatty acids on the expression of miRNAs in mammary gland of dairy cows, from the aspects of bovine mammary miRNAs expression characteristics, miRNAs that regulate milk fat synthesis, and the changed bovine mammary miRNAs in response to exogenous addition of fatty acids. All these works may be beneficial for the establishment of the connection between nutrients and mammary function, and provide information for the related research in the future.

Key words: dairy cow, fatty acids, mammary microRNAs, milk fat
