Sumario: | Recent measurements of b-baryon decays using 3$fb^{-1}$ proton-proton collision data collected by the LHCb experiment are presented. Measurements of the branching fractions of $\Lambda_{b}^{0} \rightarrow J/\psi p \pi$, $\Lambda_{b}^{0}\rightarrow \Lambda_{c}^{+}D_{s}^{-}$, $\Lambda_{b}^{0}\rightarrow \Lambda_{c}^{+}D^{-}$, and $\Lambda_{b}^{0}\rightarrow \Lambda_{c}^{+}\pi^{-}$ decays have been made, as well as precise measurements of the mass and lifetime of the $\Xi^0_{b}$ baryon. In addition, the $p_{T}$ and $\eta$ dependence of the ratio of $\Lambda_{b}^{0}$ to $B^{0}$ production fractions has been measured. |
