The uncertainties in estimating the hadronic production of the B-c meson are studied in the framework of the complete alpha(s)(4) approach of perturbative QCD and the gluon-gluon fusion mechanism. Quantitative comparisons Of the production at TEVATRON and LHC are made. Considering the detectors at TEVATRON and LHC, we have also estimated the production with proper kinematic cuts. Based on the results, we conclude that the experimental studies of the B-c meson at the two colliders will be complementary and mutually stimulative. We find that as the CM energy is increasing from RUN-I to RUN-II at TEVATRON, the production cross section increases by about 20%.
