From the Bogoliubov-de Gennes equations, we obtain the self-consistent equation for a ferromagnetic superconductor. Using the Furusaki-Tsukada formula, we calculate the dc Josephson current in superconductor-ferromagnet/insulator/spin-triplet p-wave superconductor (FS/I/p) junctions. It is found that the dc Josephson currents in FS/I/p are suppressed by the presence of exchange field and insulating barrier scattering. The period of oscillation curves of the Josephson current is π when there exist px-wave symmetries for the pairing symmetries of spin-triplet superconductor.
