Using free-space widths for the $\\Delta(1232)$ and the $N^{*}(1440)$ resonance and free-space thresholds for particle production, it is found that the $N^{*}$-baryon interactions contribute about 10\\%, 25\\% and 80\\% to the yield of kaon, antikaon and antiproton, respectively. Doubling the widths of resonances due to possible medium effects, both the total and the $N^{*}$ induced antiproton yield decrease by about a factor of 3.
