Abstract. The aim of the performed investigations was to compare eggs of Japanese quail layers of different weights with regard to their shape, selected traits of the content following various times of their storage as well as the results of hatchability and body weight of one-day old chicks. Hatching eggs were divided into four groups: group S – up to 10.50 g, group M – from 10.51 to 11.50 g, group L – from 11.51 to 12.50 g and group XL – from 12.51 g. In experiment I, on days: 1, 3, 5, 7 and 10 of storage, the following traits were assessed in 20 eggs from each group: egg weight (g) and yolk and albumen index as well as the number of Haugh units. In experiment II, five hatches were carried out. The total of 480 eggs were incubated in each hatch (120 eggs for each group). On the 15th day of incubation, the eggs were weighed. After hatching, 30 chicks from each group were weighed. Basic hatchability indices were also determined. Eggs with the smallest weight, stored for 1 day, with the smallest yolks were characterized by their highest content contrary to the eggs with the highest weight (the biggest yolks but with their smallest percentage content). In eggs with the higher weight (groups L and XL), a certain increase in weight and proportion (%) of yolk was observed after 3, 5, 7 and 10 days. The highest albumen percentage content was determined in eggs from groups L and XL, whereas in the remaining groups the albumen content was the smallest. With the lengthening of the egg storage, the albumen weight did not undergo significant changes. After one-day storage, the yolk and albumen index as well as Haugh units were slightly higher for eggs of smaller weight than for bigger ones. Eggs from groups S and M were more spherical. Eggs from groups L and XL had smaller weight losses during hatching. Eggs from group L were characterized by the best fertilization, hatchability results and proportion of dead embryos and unhatched chicks. The heaviest chicks were obtained from eggs of the highest weight, while the lightest – from eggs of the smallest weight. The obtained results appear to indicate that Japanese quail eggs of 10.51-12.50 g are the best for hatching.

Weight Groups

In this study, a total of 402 Japanese quail hatching eggs from 32 weeks of age flock to determine shell temperature, temperature differences between shell and setter temperatures, relative weight (water) loss from eggs in setter period and effects on incubation results. All the eggs were divided into two egg weight groups (≤12 g and >12 g) and they were randomly and equally distributed to the setter trays. As expected, day old chick weight was significantly affected by the egg weight. The lighter eggs lost more water than heavier ones. Although the embryo cannot produce a noticeable level of heat in the first half of the development period (endothermic phase), since it begins to generate more noticeable heat in the second half (exothermic phase), the shell temperature is found to be higher than the setter temperature. This table is more pronounced in heavier eggs. In the first half of the development period, while the shell temperature was higher in light eggs than in heavy ones, the shell temperature, in egg weight groups, was differed by the setter floors during the latter half. Generally, in this late period, when the growing embryo now produces more noticeable heat, the higher shell temperatures were measured in heavier eggs and in eggs where set in upper-trays. The lighter eggs where set in lower-trays were found to be having lower shell temperatures than the eggs in all other combinations. Late embryonic mortalities were higher in heavier eggs.

A total of 9360 eggs was used in two series of experiments to study the effect of pre-incubation treatments on hatchability, egg weight, and chick weight. These treatments involved plastic packaging, alterations in atmospheric carbon dioxide, temperature, humidity, and time during the pre-incubation stage.Hatchability was maintained at a higher level when eggs were enclosed in plastic film during the pre-incubation period. There was also evidence that plastic packaging was more beneficial when eggs were held at adverse temperatures. Temperatures from 50 to 66° F did not appear to have a detrimental effect on hatchability when eggs were held for short storage periods. An increase in the carbon dioxide concentration in the egg storage environment depressed hatchability.Long pre-incubation holding periods tended to decrease egg weight at setting time and at the 18th day of incubation but appeared to increase chick weight. Temperatures ranging from 50 to 64° F had little effect on egg and chick weights. High humidity levels increased egg weight (when eggs were not enclosed in plastic packages) but this weight difference disappeared during incubation.

Abstract. This study was undertaken to determine the effects of storage period and egg weight of hatching eggs of Japanese quails on fertility, hatchability results. Eggs were obtained 150 females quails, all at 15 weeks of age. A total of 1942 hatching eggs were separated into 3 groups as light-weight (9.50-10.50 g), medium-weight (10.51-11.50 g), and heavy-weight (11.51-12.50 g). Based on storage period, eggs were divided into 5 groups as group 1 (0-3 days), group 2 (4-6 days), group 3 (7-9 days), group 4 (10-12 days), and group 5 (13-15 days). The influence of storage period on hatchability of fertile eggs and early, middle, and late period embryonic mortality rates was found significant (P<0.01). The effect of egg weight on fertility rate, hatchability of fertile eggs and early embryonic mortality was significant (P<0.05, P<0.01). The significant differences between storage period groups were observed in hatchability of fertile eggs. The differences between egg weight groups for fertility rate, hatchability of fertile eggs and early embryonic mortality was significantly higher in light weight group than the other egg weight groups. Results of this study concluded that a 12 day pre-incubation storage of hatching eggs of Japanese quails did not appreciably affect hatching parameters. Use of medium or heavy weight eggs for hatching may reduce early embryonic mortality rate.

This study was conducted to investigate the effects of broiler breeder dietary vitamin E and egg storage time on the egg characteristics, hatchability, and antioxidant status of the egg yolks and newly hatched chicks. A total of 512 71-week-old Ross 308 breeder hens were fed the same basic diets containing 6 or 100 mg/kg vitamin E for 12 weeks. During this time, a total of 1532, 1464, and 1316 eggs were independently collected at weeks 8, 10, and 12, respectively, and subsequently stored for 0 or 14 d before hatching. The outcomes from three trials showed that prolonged egg storage time (14 vs. 0 d) negatively affected (p < 0.05) the egg characteristics, hatchability traits, and the yolk total antioxidant capacity (T-AOC) (p < 0.05). Chicks derived from the stored eggs exhibited higher malonaldehyde (MDA) and T-AOC in the serum and yolk sac (p < 0.05). Broiler breeder dietary vitamin E (100 vs. 6 mg/kg) increased (p < 0.05) the hatchability and the antioxidant status of the yolks as indicated by a higher α-tocopherol content and T-AOC and lower MDA level (p < 0.05). The supplementation of vitamin E also remarkably increased (p < 0.05) the total superoxide dismutase (T-SOD) activity (yolk sac, weeks 8 and 12) and T-AOC (serum, weeks 8, 10, and 12; yolk sac, weeks 8 and 12) and decreased (p < 0.05) the MDA content of chicks (yolk sac, week 10; serum, week 12). Interactions (p < 0.05) were found between the broiler breeder dietary vitamin E and egg storage time on the hatchability and antioxidant status of chick tissues. Broiler breeder dietary vitamin E (100 vs. 6 mg/kg) increased (p < 0.05) the hatchability and the T-AOC in the serum and liver of chicks, and decreased (p < 0.05) the early embryonic mortality and the MDA content in the yolk sacs of chicks derived from eggs stored for 14 d but not for 0 d. In conclusion, prolonged egg storage time (14 vs. 0 d) increased the embryonic mortality, decreased the hatchability, and impaired the antioxidant status of egg yolks and newly hatched chicks, while the addition of broiler breeder dietary vitamin E (100 vs. 6 mg/kg) could partly relieve these adverse impacts induced by long-term egg storage.

Abstract The aim of the study was to assess the effect of the storage time on the hatching traits of eggs obtained from a two-line dual-purpose combination for production of male chickens that will be utilized for meat. The trial was carried out in the experimental poultry farm of the Institute of Animal Science-Kostinbrod, with a total of 150 Lohmann Brown Classic layers, at the age of 54 weeks. Hatching eggs were gathered for three weeks and were stored for 5, 10 and 15 days at 15-18°C ambient temperature prior incubation. The storage time had no effect on the fertility of the set eggs, however, it adversely affected the hatchability. Prolonged storage led to significant decline in the total hatchability (P=0.0027) and the hatchability of the fertile eggs (P<0.0001) which was lowest after 15 days of storage prior incubation. The viability of the chickens was influenced by the storage of the eggs prior incubation (P<0.0001), and decreased considerably when the chicks were hatched from eggs stored for 15 days.
