The purpose of this experiment was to establish the effects of high light intensity application during embryogenesis on incubation results in Japanese quail (Coturnix coturnix japonica) eggs. A total of 360 hatching eggs were randomly divided into 2 groups. The quail eggs (n= 360) were incubated continuously in the dark (Control; C) and in continuous light at 2900 lux (Light; L) during the first 14 days of incubation. There were no significant (P>0.05) differences in hatchability and embryonic mortality among treatments groups. The incubation time in the light-treated group was shorter than C group. The higher hatch was observed in L group at 390 to 416 h of incubationperiod than the C group (P<0.01). No significant differences were found between C and L group at other hatching times. These results demonstrate that continuous high light application during incubation affected the hatch time positively without adversely affecting hatchability or embryonic mortality.
