We study the impact of baryon-antibaryon annihilation into three mesons on heavy-ion collisions. The reactions are based on the quark rearrangement model in the light and strange sector. Box simulations with periodic boundary conditions confirm that our implementation of these reactions fulfills the detailed balance relation on a channel by channel basis. We implement these reactions into the Parton Hadron String Dynamics (PHSD) transport model and investigate their importance for different bombarding energies in Pb+Pb and Au+Au collisions. We find a significant impact on antibaryons, Kaons and pions through all energies, although the influence at lower energies is more pronounced. The effect of the $B \bar B \leftrightarrow 3M$ reactions on the antibaryons rather than the baryons is notable due to the overall lower multiplicities of the antibaryons. For higher energies a significant net annihilation is found.
