“…The increased chick yield could be partly attributed to difference in egg weight loss that there was a negative correlation between egg weight loss and day-old chick weight or chick yield (−0.26 and −0.21, respectively). These results were in agreement with that chick weight was primarily determined by initial egg weight and was secondarily determined by weight loss during incubation ( Marks, 1975 , Khurshid et al., 2004 , Grzegrzka and Gruszczynska, 2019 ). These results were also supported that decreased egg weight loss during incubation could increase chick weight ( Peebles et al., 1987 , Shahein and Khalifa, 2014 ).…”

“…The Pearson's correlation analysis results showed that the shank length was correlated to initial egg weight, day-old chick weight and chick yield without being affected by egg weight loss. The Pearson's correlations reported here for initial egg weight, day-old chick weight, and shank length (0.84, 0.24, and 0.34, respectively, Table 5 ) were lower than those reported previously (0.91, 0.57, and 0.58) ( Grzegrzka and Gruszczynska, 2019 ), but this is most likely because of the reduced sample size in this trial.…”

The cuticle is the outmost layer of the eggshell and may affect the hatchability by modulating eggshell conductance. Three different solutions using acetic acid ( AA ), vinegar ( V ), and citric acid ( CA ) for cuticle removal by egg washing were developed, and the effects of cuticle removal on hatching performance of quail hatching eggs were evaluated. A total of 5,238 fresh quail hatching eggs were randomly divided into 9 treatments as follows: unwashed control, nondipped ( CND ); washed control, water dipped ( CWD ); standard control, 0.13% sodium hyperchlorite ( CSH ); 2% AA ( AA2 ); 4% AA ( AA4 ); 44.4% V ( V2 ); 88.8% V ( V4 ); 2% CA ( CA2 ); and 4% CA ( CA4 ). Overall, AA4, V4, and CA4 treatments significantly improved the hatchability of fertile eggs (95.42%, 94.16% and 95.66%, respectively) ( P < 0.05) and the hatchability of CND, CWD, CSH, AA2, V2 and CA2 treatments were 90.98%, 93.00%, 92.27%, 79.44%, 90.37%, and 90.59%, respectively. The eggshell thickness and cuticle quality results showed that all AA, V, and CA solutions can effectively remove the quail eggshell cuticle, and AA4, V4 and CA4 significantly decreased eggshell thickness ( P < 0.05). Microbial activity on the eggshell surface in all acid treatments was reduced significantly at day 0 of incubation ( P < 0.05) and that significantly decreased than controlled treatments over the incubation period except AA2 treatment. Egg weight loss was lower for all acid treatments than that of the CND treatment ( P < 0.05). There was no clear effect of treatments on chick quality. Hatch time in AA4, V4, and CA4 treatments slightly improved compared with controlled treatments ( P > 0.05). There were no significant differences between treatments for chick livability and live weight at the first 21 D of life. Results of the present study indicate that cuticle removal with AA4, V4, or CA4 could effectively decrease the microbial activity on the eggshell surface during the incubation period and improve hatchability of quail hatching eggs without negative effects on hatch time and performance of quail chicks.

“…Regarding residual yolk sac weight, chicks from eggs stored for 3.5, 6.5, and 9.5 days, pre-heated or not, showed significantly lower results than the control group (p<0.05). The birth weight of Japanese quail is directly linked to egg weight (Grzegrzółka & Gruszczyńska 2019;Chimezie et al, 2020). Thus, the lower weight values of newly hatched chicks obtained in this study are attributed to the lower egg weight.…”

This study investigated the effects of pre-heating fertile Japanese quail eggs during storage on embryonic development, incubation performance, hatched chick quality, and chick performance up to 35 days of age. The experiment was laid out in a completely randomized design in a 3 × 2 + 1 factorial arrangement, totaling seven treatments. These treatments included three storage periods (3.5, 6.5, and 9.5 days) and two pre-heating periods (0 and 4 h at 37.5°C and 60% RH). Pre-heating was conducted on the third day of egg storage inside the incubator machine, with the control treatment involving the storage of fertile eggs for 12 h without pre-heating. Extended egg storage for more than six days led to an increase in the percentages of yolk and shell, elevated albumen pH, reduced albumen percentage, diminished hatchability rate, and an increased embryonic mortality rate. Pre-heating the eggs resulted in a reduction in the weight, length, and amount of residual yolk sac of the newly hatched chick. No significant effects of pre-heating fertile Japanese quail eggs during storage were observed on the studied variables. Therefore, the protocol involving a 4-h pre-heating at 37.5 ºC and 60% relative humidity during the storage period does not yield improvements in incubation rates or chick quality in Japanese quail. Further studies are warranted to determine the optimal protocol for pre-heating Japanese quail eggs.

“…The reduction in different reproduction traits, such as egg production, fertility, and hatchability due to selection for body weight which has a positive effect on egg weight increase (Anthony et al, 1996 andNestor et al, 2008). There were correlations between both embryo development and hatchability with hatching egg weight (Rocha et al, 2008 andGrzegrzółka andGruszczyńska, 2019). It is well known that genetic background of lines affected the differences of these traits (Brah et al, 2001).…”

This work aimed to study the effects of selection for fast growth rate on some laying and fitness performance in Japanese quail using 1157 females (706 for the selected line and 451 for the control line). The most important results obtained as follows: Generation significantly affected all egg studied traits indicating that the 4 th generation (G4) had the earliest age at first egg (AFE) and age at the first ten eggs (AGE10) accompanied by the heaviest body weight at first egg (BWAFE) and desirably had lower days needed to produce the first ten eggs (DN10) and laid heavier average egg weight (AEWFM) (48.98 day, 60.87 day, 260.77 g, 13.12 day and 11.88 g respectively) and had higher number of eggs (ENFM), heavier egg mass for the first month of production (EMFM), and favorably lower pause duration length (PDLFM) than other generations being of 24.53 egg, 291.32 g and 1.76 day, respectively. Moreover, the G4 had higher fertility (88.20%) and hatchability (85.42%) associated with preferably lower early and late embryonic mortality% than other generations. The selected line attained AFE at earlier age (50.63 day) with heavier BWAFE (260.59g) and lower DN10 (14.06 day) and AGE10 (64.44 day), laid more ENFM (22.63egg), higher EMFM (263.67g), earlier age after first month of production (AGEFM, 80.63 day), larger clutch size (CSFM, 5.20) and shorter PDLFM (1.89 day) and had preferably higher fertility (80.69%), hatchability (74.14%) but undesirably higher early embryonic mortality% (2.68%) than the control line. There were favorable negative correlations between growth rate during 1-21 days of age (GR1-21.) And each of AFE, DN10, AGE10, PDLFM and AGEFM and had preferably positive rg's with each of BWAFE, ENFM, EMFM, clutch number for the first month of production and CSFM, it seemed these traits can be indirectly improved through the selection for fast GR1-21.
