The study of heavy-flavour mesons and baryons in hadronic collisions providesunique access to the properties of heavy-quark hadronisation in the presence oflarge partonic densities, where new mechanisms of hadron formation beyondin-vacuum fragmentation can emerge. Performing these measurements in intervalsof charged-particle multiplicities across different collision systems providessensitivity to understand whether different hadronisation mechanisms are atplay in small and large hadronic colliding systems.  In this contribution, a selection of the latest charm and beauty productionmeasurements in proton--proton (pp) collisions is presented, which can shedlight on the modification of the heavy-quark hadronisation mechanisms withrespect to leptonic collisions. New published results of the production of allprompt charm ground states in pp collisions at $\sqrt{s}=13$~TeV, which allowedus to measure the charm fragmentation fractions and the total $\rm c\bar{c}$production cross section at midrapidity, will be shown. The new finalmeasurement of non-prompt (i.e. originating from beauty-hadron decays) $\rm\Lambda_c^+$ baryons in the same collisions system will be discussed to providea quantitative comparison between the hadronisation properties of beauty andcharm hadrons. New measurements of $\rm \Xi_c^0$ production as a function ofcharged-particle multiplicity in pp collisions at $\sqrt{s}=13$~TeV, and of$\rm \Xi_c^0$ production in p--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$~TeV,will be also presented, shedding further light on the hadronisation ofcharm-strange baryons in different colliding systems.
