Abstract: Let $t\geq 2$ be an integer, and let $p_1,\cdots, p_t$ be distinct primes. By using algebraic properties, the present paper gives a sufficient and necessary condition for the existence of non-trivial self-orthogonal cyclic codes over the ring $Z_{p_{1}p_{2}\cdots p_{t}}$ and the corresponding explicit enumerating formula. And it proves that there does not exist any self-dual cyclic code over $Z_{p_{1}p_{2}\cdots p_{t}}$.
