Changes in the timing of lung ventilation and late foetal development in quail

Photoacceleration of Embryonic Development in Depigmented Japanese Quail Eggs

“…Since the different groups hatched from 15 days to 18 days depending upon their grouping, it shows that pigmented and depigmented eggs exposed to light, or incubated in the dark, show the coordinated hatching demonstrated by Vince (1966) and Vince et al (1970). Hatching of pigmented eggs exposed to light was accelerated when adjacent to depigmented eggs exposed to the light, but did not themselves speed up the pigmented eggs in the dark.…”

“…Genetic variations in the progenies of the diallel crosses of inbred lines of chicken. Vince et al (1970) showed also that lung ventilation noises affected coordinated hatching in Japanese quail, but not in Bobwhite quail; however, pipping vibrations affected both species. 40: 1048-1062.…”

“…Yao, T. S., 1961. Coordination of hatching times has been shown to be affected by vibration (Vince, 1966) and noises associated with lung ventilation (Vince et al, 1970). Poultry Sci.…”
