First minimum bias physics results at LHCb

We report on the first measurements of the LHCb experiment, as obtained from pp collisions at s=0.9TeV and 7 TeV recorded using a minimum bias trigger. In particular measurements of the absolute KS0 production cross section at s=0.9TeV and of the Λ¯/Λ ratio both at s=0.9TeV and 7 TeV are discussed and preliminary results are presented.
