“…However, Majhi et al (2016) and Amiar et al (2017) noted a gradual decrease in embryo mortality of incubated eggs from the beginning to the peak period of laying. In the same trend, Seker et al (2004) recorded an improvement in the embryonic mortality rates of fertile eggs over the two periods of the reproductive cycle.…”

“…The effects of breeder age were observed on the eggs' external and internal characteristics (Zita et al, 2013;Nasri et al, 2020), the eggs' fertility (Majhi et al, 2016), and embryonic development (Pokhrel et al, 2018). Several studies have revealed that during a laying period the weight of the eggs increases with the age of the breeders (Nasri et al, 2020).…”

Egg quality traits in quail breeders depend on various factors which may influence embryo survival during incubation, affecting the chicks' production and quality. The current study aimed to determine the effect of the laying period on the external and internal quality of the egg, the chemical composition of albumen, yolk, and eggshell as well as the reproductive parameters of quail breeders. A total of 450 quails (Coturnix japonica) obtained from the same hatchery, were reared in a battery cage with a sex ratio of 1 male to 3 females. All the quails were subjected to standard breeding conditions and fed a balanced laying diet. A total of 960 eggs were collected at two different periods of the laying cycle, the beginning period of the laying (BP indicating 10 weeks of quail age) and the peak period of laying (PP showing 20 weeks of quail age). At each laying period, 30 eggs were used to analyze the various parameters of egg quality, and 450 eggs were randomly selected to assess the reproductive performances. Overall, no differences in the external quality of eggs, such as egg length, egg width, and the egg shape index, were recorded between the two laying periods. Apart from albumen weight that tended to be higher at the peak laying period, the shell and the yolk weights were not affected by the period of laying. Additionally, Japanese quail tend to deposit similar proportions of shell, albumen, and yolk at the two periods of laying. Likewise, the rate of dry matter of the three egg components, shell mineral concentrations, and yolk fat concentrations did not show any noticeable variation with the laying period. The most significant effect of the laying period was related to the potential reduction in the total protein content of the albumen and the yolk of eggs laid at the peak period of laying. Finally, the laying period did not significantly affect the fertility and hatchability rate of the incubated quail eggs but slightly improved the embryonic mortality rate during the peak laying phase.

“…In comparison, Yilmaz et al [ 12 ] state that non-shiny eggs are unsuitable for hatching due to their increased porosity, endangering the embryo’s viability. As a result, non-shiny eggs are related to decreased mineralization and increased contamination rates, both of which impair embryo survival [ 13 ].…”

Objective: The influence of the degree of pigmentation, shine, weight, and form index on the hatchability rate of quail eggs ( Coturnix coturnix japonica ) was examined. Materials and Methods: Three thousand three hundred eggs were incubated after they were classified according to the degree of shell pigmentation: high (HP), medium (MP), and low (LP); shell shine: shiny (SS), and opaque; Egg weight: <11, 11.0–11.9, 12.0–12.9, and >13 gm; form index: <78% and >78%. The Mann–Whitney non-parametric test for independent samples was used to evaluate hatching data. Results: Hatchability was best in eggs with HP and SS ( p < 0.05): 69.2% and 75.7%, respectively; eggs with MP had the lowest hatchability rate (63.1%). The highest risk of embryo death (17.8%) was observed in eggs containing LP ( p < 0.05). Eggs weighing between 12 and 12.9 gm had the highest hatchability rate (p < 0.05) (79.11%). Eggs with a form index >78% had the highest hatchability rate ( p < 0.05) (67.62%). Conclusions: HP, MP shell eggs, and SS eggs with a weight of between 12.0 and 12.9 gm and a shape index of greater than 78% have a higher hatchability rate.
