We study $\Lambda _c/\overline{\Lambda}_c$ production asymmetries in pp and $\pi^{-}p$ collisions using a recently proposed two component model. The model includes heavy baryon production by the usual mechanism of parton fusion and fragmentation plus recombination of valence and sea quarks from the beam and target hadrons. We compare our results with experimental data on asymmetries measured recently.
