Abstract: MicroRNA (miRNA), a class of non-coding RNA (about 22 nt), widely exists in different organisms and plays an important role in growth, development, and apoptosis. Recently, many studies have shown that miRNAs serve as a regulatory mechanism in mediating the development of pig muscle, fat, reproductive and immunity traits. The next-generation of high-throughput sequencing technology plays a critical role on finding new miRNAs and identifying their different expressions in pig. In this review, we summarize the application of the next-generation of high-throughput sequencing technology in the study of pig miRNAs as well as the regulatory roles of several important miRNAs in fat metabolism, muscle development, oocyte maturation and development of B cells and T cells. This review will provide insight into the research on pig miRNAs, and some ideas on how to improve pork quality, growth, reproductive and immunity performance.

Key words: porcine, miRNA, fat metabolism, muscle development, oocyte maturation, immunity
