Abstract: The Noether-Mei symmetry and the conserved quantity of a Birkhoffian system are studied. The definition and the criteria of the Noether-Mei symmetry of the system are given.The conditions that the Noether-Mei symmetry leads to the Noether conserved quantity or the Mei conserved quantity and the form of the conserved quantities are obtained.Two theorems for the Noether-Mei symmetry and the con-served quantity are established.At the end,an example is given to illustrate the application of the re-sults.
