Abstract: The mean multiplicities of mesons π±, π0, K±, Ks0, K*0, K*±, and φ and baryons p, Ξ±, and ∑± (1385) are measured for the first time at J/ψ region with 200,000 events collected at the BEPC with the BES detector. The results are compatible with LUND and Shandong phenomenological models. Based on the experimental results, the strangeness suppression factor s/u and spin suppression factor V(V+P) can be calculated to be ~0.3 and ~0.3-0.5, respectively, which are in good agreement with those given by the ARGUS Collaboration in the Υ region. This indicates that the SU(6) breaking is consistent in the energy region from J/ψ to Υ.
