1. Myoblast proliferation and differentiation is one of the most important biological processes in the development of skeletal muscle. MicroRNAs (miRNAs) play a crucial role in this process. 2. In this study, the expression level of miR-181a-5p was detected, which found that miR-181a-5p was expressed differently in different tissues, different embryonic ages, and different differentiation stages of primary myoblasts in Gushi chickens. 3. The effect of miR-181a-5p was further investigated on chicken primary myoblasts (CPMs). The results of cell counting kit-8 (CCK-8), 5-ethynyl-2’-deoxyuridine (EdU) and cell cycle showed that miR-181a-5p could inhibit the proliferation of CPM. The miR-181a-5p promoted the expression of  MYOD, MYOG , and  MYHC . MYHC protein immunofluorescence experiments showed that miR-181a-5p increased the area of myotubes. 4. In total, 63 potential target genes of miR-181a-5p in  mRNA  transcriptome data analysis were identified. Functional enrichment analysis was performed on these target genes, and  ASNS, SMYD1 , and  FOS  were found to play regulatory roles in biological processes such as muscle development. It was speculated that miR-181a-5p played a role in myoblast development through these genes. 5. In conclusion, miR-181a-5p can inhibit the proliferation of chicken myoblasts and promote the differentiation of chicken myoblasts. This study laid the foundation for further research on the regulatory mechanism of miR-181a-5p in the development of skeletal muscle and the formation of excellent meat quality traits in Gushi chicken.
