Abstract: -This study was carried out to investigate the effects of eggshell colour and spot properties (colour and size of the spot area) on eggshell incubation temperature and hatching outcomes of Japanese quail eggs (Coturnix coturnix japonica). Study material was allocated to five groups according to their eggshell and spot colours: black spots on greyish white coloured eggshell (I), blue spots on greyish white coloured eggshell (II), diffuse brown spots on greyish brown coloured eggshell (III), brown spots on light… Show more

“…Storage x transportation interaction was not significant for this trait. The present findings in the third period for embryonic mortality ratios for two storage periods were different from the values that Aygun & Sert (2013) reported for the same duration, as 1.39% and 2.195, and from the findings of Alasahan et al (2016), who investigated the effects of egg shell colour and spot size on hatching parameters (1.9% and 2.9%). The embryonic mortalities of the present third period were lower than the values of Copur Akpinar et al (2017) (11.85%) and those of Lacin et al (2008), which were reported for 3-, 8-and 14-day storage as 19.2%, 31.3% and 47.5%, respectively.…”

“…The present second-period embryonic death ratios of 7-(2.4%) and 14-(5.76%) day storage were higher than those reported by Aygün & Sert (2013) for 7-(2.18%) and 14-(2.79%) day storage. On the other hand, these findings were lower than those reported by Alasahan et al (2016), who investigated the effects of colour and spot sizes on hatch outcomes of quail eggs (5.6% -10.8%). Average second-period embryonic mortality was 4.08% in the present study.…”

“…Biliverdin and protoporphyrin are both produced in the oviduct gland and then deposited in the eggshell concurrently [ 7 ]. The color of the eggshell has been reported to affect both its quality and biological value [ 8 10 ]. This is even though environmental influences such as relative humidity and storage time cannot be ruled out [ 11 ].…”

“…Apart from the shell color, the morphological characteristics of the quail egg also influence the hatchability and growth of the embryo [ 10 ]. According to several findings, hatching eggs with a smooth, shiny surface have a higher hatchability rate [ 9 ].…”
