“…The highest average SI was observed in group GG (78.31±0.53%), vs the lowest in WG quails (77.55±0.62%). Our data about shape index agreed with those of other researchers having assessed quail egg quality (8,(11)(12)(13)(14)(15). From the surface inward, the egg consists of a shell with membranes, albumen and yolk.…”

“…Wilkanowska and Kokoszyński (19) reported similar but lower values than ours. Higher values for yolk were also demonstrated (14,15,20). The shell comprised between 10.95 and 12.58% of egg weight on the average, with highest between-group variation of 12.93%, compared to other egg parts.…”

The aim of the study was to evaluate egg quality traits in three heavy Japanese quail populations created and reared in the Poultry Breeding Unit of the Trakia University – Bulgaria, marked as WG, GG and GL. In the experiments, 160 female birds from populations WG and GG, and 96 birds from population GL were tested up to the 6th production month. The main egg quality traits were controlled. The highest average egg weight was registered in WG group and the lowest in GL group, 14.04±0.32 g and 12.79±0.29 g respectively (p<0.05). The highest average Shape index was observed in group GG (78.31±0.53%), vs the lowest in WG quails (77.55±0.62%). Albumen proportion is almost 2/3 of egg mass, with average values from 57.14% in group WG tо 59.90% in group GG. Yolk proportion was about 30%, with smaller differences between the groups. The shell share from all tested groups comprised between 10.95 and 12.58% of egg weight. Average shell thickness was the greatest in eggs of WG quails (223.53±5.52 μm), and the lowest – in GG quails (216.91±6.83 μm). Egg quality traits were typical for the meat productive type of Japan quails.

“…In the present study, the average egg weight of the yellow Japanese quail (Coturnix japonica) was determined 12.23 g. The following weight values were previously reported: 11.28 g by Kul & Seker (2004); 11.06 g by Sezer (2007); 11.43 g by Alkan et al (2010); 11.14-12.84 g by Ozdemir & Inci, (2012); 11.52-12.30 g by Stojčić et al (2012); 8.19 g by Ojedapo (2013); 13.06 g and 11.48 g for meat and layer types, respectively, by Hrncar et al (2014); 12.70 g by Alasahan et al (2015); and 12.20-13.26 g by Hanusová et al (2016). Average eggshell weight was determined as 0.85 g in the present study, which was previously reported as 0.84 g by Kul & Seker (2004), 0.96 g by Sezer (2007), 1.00 (0.84-1.15 g) by Alkanet al (2010), 1.73-1.80 g by Stojčić et al (2012), 0.94 g by Ojedapo (2013), 1.09 g by Alasahan et al (2015), and 1.12-1.21g by Hanusová et al (2016). In the present study, albumen and yolk weights were determined as 6.93 g and 4.45 g, respectively, and previously reported as 6.75 g and 3.69 g by Kul & Seker (2004), 6.07-7.08 g and 3.42-3.72 g by Stojčić et al (2012), 6.35-7.44 g and 3.86-4.54 g by Ozdemir & Inci (2012), 4.95 g…”

“…The early (12.39%) and late (4.29%) embryonic mortality rates reported by Farghly et al (2015) for brown spotted eggs are similar to those determined in the present study. In the studies conducted by Alasahan & Copur (2016) and Alasahan et al (2015) on the influence of egg shape index and eggshell color and spot are a on hatching results, respectively, early embryonic mortality rates were much higher than the late embryonic mortality rates.…”

This study was carried out to investigate selected traits of hatched and unhatched eggs and chick growth performance of yellow Japanese quails (Coturnix japonica). Eggshell temperature at the time of transfer to the hatcher was higher in hatched eggs (38.09 o C) than in unhatched eggs (37.43 o C) (p=0.000), lower in eggs with in early embryonic mortality (37.39 o C) than those with late embryonic mortality (38.13 o C) (p=0.000), and higher in eggs with female chicks (38.14 o C) than those with male chicks (37.95 o C). Lower eggshell, yolk, and albumen weights were determined in eggs with embryonic mortality of 17-18 days (0.58 g, 3.13 g and 4.96 g) compared with those with 10-16 days (0.67 g, 3.55 g and 5.58 g) and embryonic mortality of 1-9 days (0.75 g, 3.95 g and 6.19 g) (p=0.000). Lower egg weight loss was obtained in eggs with embryonic mortality (13.85%) of 1-9 days than those with embryonic mortality of 17-18 days (26.48%) (p=0.001). Females were heavier at chick weight (8.98 g vs. 8.63 g; p=0.033) and at 4 (231.81 g vs. 211.43 g; p<0.000) and 5(260.69 g vs. 231.87 g; p<0.000) weeks of age than males, and had longer left shanks (34.39 mm vs. 33.61 mm; p=0.004).
