#### Abstract

Peking duck embryos incubated for 82 hrs after oviposition, stage 18 to 20(Hamberger and Hamilton, 1951) were transferred into the recipient eggshells and further incubated at $38.0^{\circ}C$ RH(relative humidity) 60 to 70%, with rotation at an angle of $30^{\circ}$ and the frequency of 4 times an hour. The survival rate was 100, 98, 82, 82, 70, 46, 21 and 16%, after the incubation period of 4, 8, 12, 16, 20, 24, 28 and 29 days, respectively. The present result clearly shows that the ex ova culture is possible for the Peking duck just as in the cases of the chicken or the quail. This culture technique could be useful for experimental manipulation of the embryos.
