QCD studies in the forward region at LHCb

The LHCb experiment at the LHC is fully instrumented over a unique pseudorapidity range in the forward region. Although it has been designed for b-physics, LHCb is able to provide valuable informations on particle production in this region of phase space. Therefore QCD studies have been performed with the LHCb detector on pp collisions at \sqrt(s)=900 GeV and \sqrt(s)=7 TeV. The measurement of charged particles multiplicity at \sqrt{s}=7 TeV}, \bar(Lambda)/Lambda, \bar(Lambda)/K_s^0 production ratios at \sqrt(s)=900 GeV and \sqrt(s)=7 TeV, as well as light hadrons (p,K,pi) production ratios at \sqrt(s)=900 GeV and \sqrt(s)=7 TeV are reported.
