To search for DNA-based sex identification candidate marker of poultry, whole blood DNAs from each five males and five females of Native Chicken, Brown Tsaiya, Muscovy, White Roman Goose, Bronze Turkey, Australian Black Swan, Quail and Ring-necked Pheasant were analyzed by spindlin gene. PCR products were amplified by SPIN12 and SPIN13 primer kits. Different electrophoresis patterns showed correct gender for each bird species. The accuracy of sex identification was 100%. Furthermore, the PCR DNA fragments of the same gender were different among bird species.
