In this paper, we study the existence of periodic solutions of the following differential delay equations begin{document}$ begin{equation} z^{primeprime}(t) = sumlimits_{k = 1}^{M-1}(-1)^kf(z(t-k)), notag end{equation} $end{document} where begin{document}$ fin C(mathbf{R}^N, mathbf{R}^N) $end{document}, begin{document}$ M,Nin mathbf{N} $end{document} and begin{document}$ M $end{document} is odd. By making use of begin{document}$ S^1 $end{document}-geometrical index theory, we obtain an estimation about the number of periodic solutions in term of the difference between eigenvalues of asymptotically linear matrices at the origin and at infinity.
