ABSTRACT
A surrogate eggshell incubation system is a well-defined method to apply to avian genetic modification. In this study, we tried to investigate whether the egg weight differences between donor and surrogate eggs have an effect on donor viability. The groups were divided by egg weight differences between the donor and surrogate eggs into 4 in each system. The viability at d 4 was evaluated at the end of System II, the embryos alive were transferred into the second surrogate eggshells, and the viability at d 5, 6 was evaluated at early phase of System III. Then, the viability of System III was evaluated at different incubation period d 6-12, d 13-18, d 19-21, and hatching rate was evaluated at d 22. Although the effect of egg weight differences between the donor and surrogate eggs was not observed, a specific group in System III showed higher survival and hatching rate than other group (P > 0.05).
