A fit of the theoretical result to the total cross-section $e^{+}e^{-}\\rightarrow D\\bar{D}$ is performed, leading to a good description of data ($\\chi^{2}/d.o.f.\\sim 1.03$). The partial cross sections $e^{+}e^{-}\\rightarrow D^0\\bar{D}^0$ and $e^{+}e^{-}\\rightarrow D^+D^-$ turn out to be separately in good agreement with the experiment.
