Abstract: Provided is a pig genome-wide specific sgRNA library, a preparation method therefor, and an application thereof. The sgRNA is targeted at a pig genome-wide protein-coding gene, lincRNA and/or miRNA. Specifically, an sgRNA construct has the following structure: AL-N20-AR, wherein AL is the left homology arm sequence located at the upstream of the coding sequence of a pig specific SgRNA, N20 is the coding sequence of the pig specific SgRNA, and AR is a right homology arm sequence located at the downstream of the coding sequence of the pig specific sgRNA. The sgRNA library can be used for screening functional genes of a pig or for preparing a kit.
