Sumario:The LHCb detector at the LHC has a pseudorapidity coverage $(2 < \eta < 5)$ which allows it to perform particle production measurements in a kinematic region where QCD models have large uncertainties. Selected analyses on particle production measurements in $pp$ collisions are summarised in these proceedings. The energy flow has been measured separately for different event classes allowing to probe multi-parton interactions at large $\eta$. The measured prompt hadron ratios are important for hadronisation models, while the $ \bar {p}/p$ ratio is a good observable to test models of baryon number transport. Charm production has been studied to determine cross-sections and production ratios. All measurements are compared to a variety of theory predictions.
