摘要：
The adaptive advantages were studied of long, daily cyclical interruptions of incubation for the hatching of Japanese quail. The aim was to mimic in a more pronounced form the natural cyclical variations to which avian embryos may be subjected and still survive. The results indicated that by consecutive daily 8-h interruptions of incubation it was possible to lengthen the embryonic period by one-third without apparent harm and with potential improvement in hatchability. After consecutive daily 12-h interruptions of incubation the length of the embryonic period could be doubled to 33 to 34 days; however, only about one-fourth as many embryos as in the control group hatched.
