Abstract	The baryon-to-meson and meson-to-meson production ratios of heavy quarks are well suited to study the hadronization mechanism. Here we will present LHCb results on the production ratios of $B_{s}^{0}/B^{0}$, $D_{s}^{+}/D^{+}$ and $\Lambda_{c}^{+}/D^{0}$ in differents collision systems. These measurements show cross-sections ratios $B_{s}^{0}/B^{0}$, $D_{s}^{+}/D^{+}$ increase with multiplicity and imply that there may be hadronization mechanisms other than fragmentation mechanisms in high-multiplicity collisions.
