Pork provides substantial portion of daily meals for human. To meet the global demand for growing population, implementation of advanced technologies in pig breeding is required. The most recently gene editing CRISPR/Cas9 system provides novel tools to pig breeders to improve animal welfare, productivity, and performance. This paper aims to give principles of genome editing techniques and the latest update on CRISPR/Cas9 application on pig industry. We will also review the possible choices for
