Electroweak and QCD measurements at LHCb

The LHCb experiment at the LHC is fully instrumented over a unique pseudo-rapidity 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. We summarize in this paper the electroweak bosons production measurement performed at root s = 7 TeV during the first half of 2010 data taking and the (L) over bar/Lambda, (L) over bar /K-s(0) and (p) over bar /p production ratios measurements performed at root s = 900 GeV and root s = 7 TeV.
