The Higgs-strahlung process e+e- $\rightarrow$ ZH and the double Higgs-strahlung process e+e- $\rightarrow$ ZHH are very important for studying Higgs boson properties and the Higgs self-coupling in the high-energy e+e- collider (ILC). We calculate the contributions of the left-right twin Higgs (LRTH) model to these processes and find that, in the favorable parameter spaces, the LRTH model can generate significant corrections to the production cross-section of these processes. We expect that the possible signals of the LRTH model can be detected via these processes in the future ILC experiments.
