In the framework of the topcolor-assisted technicolor (TC2) model we investigate the flavorchanging neutral-current production pp \\to t\\bar{c}h^{0}_{t}at the LHC, which proceeds through the parton level processes gg \\to t\\bar{c}h^{0}_{t}, u\\bar{u} \\to t\\bar{c}h^{0}_{t} and d \\bar{d} \\to t\\bar{c}h^{0}_{t}. We calculate the production rate and present the distributions of the transverse momenta and the invarient mass of the neutral top-higgs. We find that the cross section of pp \\to t\\bar{c}h^{0} _{t} can reach a few hundreds fb in a large part of the allowed parameter space. Considering the main decay mode of top-higgs for m_h_{t} < 2m_{t}, we find that such a production may provide copious events. In case of unobservation, the LHC can set meaningful constraints on the TC2 model.
