Abstract: We report on the first measurements of the LHCb experiment, as obtained from$pp$ collisions at $\sqrt{s} = 0.9$ TeV and 7 TeV recorded using a minimum biastrigger. In particular measurements of the absolute $K^0 S$ production crosssection at $\sqrt{s} = 0.9$ TeV and of the $\bar{\Lambda}-\Lambda$ ratio bothat $\sqrt{s} = 0.9$ TeV and 7 TeV are discussed and preliminary results arepresented.
