  We study the formation of fluid vorticity and the hyperon polarization in
heavy-ion collisions at NICA energies in the framework of the
Parton-Hadron-String Dynamic Model, taking into account both hadronic and
quark-gluonic (partonic) degrees of freedom. The vorticity properties in
peripheral Au+Au collisions at $\sqrt{s_{NN}}=$7.7\,GeV are demonstrated and
confronted with other models. The obtained result for the $\Lambda$
polarization is in agreement with the experimental data by the STAR
collaboration, whereas the model is not able to explain the observed high
values of the anti-hyperon $\bar\Lambda$ polarization.
