In this paper, we develop Kaplan–Yorke's method and consider the existence of 2r/(2k+1)-periodic solutions for certain three-dimensional delay differential systems. We also study Hopf bifurcations of this kind of periodic solutions for the system with a parameter and present some application examples of our main results.

We obtain some existence results for multiple positive periodic solutions of some delay differential systems. Examples are presented as applications. For a general positive integerm≥2, main results of this paper do not appear in former literatures as we know. Comparing with the existing results, our results are new also whenm=1.
