We h a v e updated our results on identi ed charged hadron production using the full SLD data sample of 550,000 hadronic Z 0 decays taken between 1993 and 1998. The SLD Cherenkov Ring Imaging Detector allows the identi cation of clean samples of charged pions, kaons and protons over a wide momentum range, providing precise tests of perturbative QCD calculations and of fragmentation models. We h a v e studied avorinclusive Z 0 decays, as well as decays into light, c and b avors, selected using

In addition we h a v e updated our comparison of hadron and antihadron production in light quark rather than antiquark jets, selected using the high SLC electron beam polarization. Di erences between hadron and antihadron production at high momentum fraction provide precise measurements of leading particle production and new, stringent tests of fragmentation models.
