  The conventional description of heavy-flavour hadron production in pp
collisions is based on a factorisation approach, assuming universal
fragmentation functions among collision systems. Recent results on
heavy-flavour baryon measurements from the LHC experiments show tensions with
model calculations based on this approach and employing fragmentation functions
constrained from $\rm e^+e^-$ and $\rm e^-p$ collision experiments. In this
contribution, the most recent results from ALICE, ATLAS, CMS and LHCb
experiments on the heavy-flavour hadron production in pp collisions at the TeV
scale are reported. The comparison with the theoretical predictions that
address the baryon enhancement in hadronic collisions at the LHC is also
discussed.
