“…In terms of body weight, the differences between wild-type and white, dark brown, and golden quail were 5.4, 8.3, and 7.6 g, respectively. This result is similar to findings of Yannakopoulos and Tserveni-Gousi (1987) and Tserveni-Gousi (1987). White-color quails had lighter LW than the wild-type.…”

-The objective of this study was to compare fattening performance, carcass traits, and egg quality of Japanese quails with different feather colors (white, dark brown, golden, and wild-type). In the study, 360 one-day-old quail chicks with 4 different feather colors were used as animal material. Quails were fed ad libitum for 42 days to determine fattening performance and carcass traits. To determine egg traits, 48 hens from each group, in a total of 192, were selected and caged according to feather color. Eggs were collected for four consecutive weeks and egg quality characteristics were measured. Different feather colors had a significant effect on live weight, feed intake, feed conversion ratio, and carcass characteristics. Significant differences between the groups were detected for egg weight, specific gravity, shape index, shell weight, albumen weight, yolk weight, albumen index, and yolk index. Japanese quails with all four feather colors can be reared depending on the choice. However, due to lower feed conversion ratio, white-feathered quails may be preferred for meat production purposes. Color variations should be considered when selecting quails.

“…In this study, neither the PRESI nor the breeder age significantly influenced the subsequent body weight of the progeny. The result for the progeny body weight was not similar with the findings of Shanawany [16], Tserveni-Gousi [21] and Yannakopoulos et al [23], who reported that the weight gain of chicks can be affected by parental age. Egg storage for 15 d significantly depressed the body weight of quail probably due to an increase of second grade chicks at hatch after prolonged storage time.…”

-A total of 1800 quail eggs were collected from two different flocks aged 20 and 37 wk. Prior to storage, half of the eggs were exposed to a prestorage incubation of 8 h (PRESI) and the other half were not (control). Eggs at 8 h PRESI were incubated at a standard dry-bulb temperature of 37.5 °C. After the PRESI treatment, all eggs were stored as the controls at 15 °C and 65% relative humidity for 5 or 15 d and were turned twice a day. All eggs were weighed prior to and after storage, then incubated in a commercial setter and hatcher for 17 d. After incubation, all unhatched eggs were opened to determine fertility, hatchability and stage of embryonic death. The PRESI treatment of 8 h significantly improved the hatchability of the total eggs (82.6%) compared to the control (79.7%). The hatchability of total eggs obtained from young breeders was significantly greater (84.7%) compared to that of old breeders (77.6%). No significant difference was observed for the hatchability due to the length of storage. Subsequent growth performance of progeny was not significantly influenced by the tested main effects, except for the storage treatment. The average body weight of 42 dold quails hatched from eggs stored for 5 d was (191.3 g) higher than after 15 d of storage (174.4 g). PRESI (8 h) reduced mortality and feed conversion ratio (FCR) of quails issued from young breeders and not that of quails issued from old breeders. It also improved the FCR of 42 d-old quails to a larger extent when the eggs were stored for 15 d compared to 5 d (interaction, P < 0.03). It is concluded that 8 h PRESI does not have a detrimental effect on the hatchability of eggs and may even increase hatchability and subsequent performance of progeny issued from young breeders. Further research is needed to precisely determine the number of hours of PRESI required for maximum hatchability.quail / incubation / egg storage / breeder age / reproduction / growth Résumé -Les effets d'une pré-incubation sur l'éclosabilité des oeufs de cailles reproductrices et la croissance des cailleteaux.

“…These results can also be because larger eggs have higher yolk weights and higher phospholipid and protein contents at the end Influence of European Quail Breeders Age on Egg Quality, Incubation, Fertility and Progeny Performance of the incubation period, when there is a transfer of nutrients from the yolk sac to the embryo, and result in larger chicks at hatch and better development of birds during the rearing period (Noble et al, 1986;Ding & Lilburn, 1996). Analyzing Japanese quail breeders from 42 to 154 days, Yannakopoulos & Tserveni-Gousi (1987) described a positive correlation between chick weight and egg weight. Breeders between 70 and 120 days laid larger eggs (12.4g), with better hatchability (72.2%) and larger chicks when compared to the other age groups analyzed.…”

The influence of age (85, 140, and 270 days) of European quails breeders on the egg quality and hatching, fertility and progeny performance was evaluated. The experimental design was completely randomized in a 3x3 factorial arrangement (females' age x males' age), with ten replicates and six birds per experimental unit (four females and two males). Egg production and quality were determined during 3 periods of 14 days and incubation parameters were evaluated in eggs obtained in five consecutive days. The live performance of the progenies was analyzed until 35 days. There was no effect of male age or any interaction between the age of males and females for the evaluated variable. The female's age influenced egg production, egg weight and chick weight, with better results obtained for 140-d-old breeders. The age of females reduced the hatchability, increased the late mortality in incubated eggs, and had no effect on fertility, total embryo mortality or eggshell structure, when analyzed by electron microscopy. The number of sperm trapped in the outer perivitelline layer (sptz/mm²) was determined in 10 fertile eggs per experimental unit. Young females fertilized by young males (80 days) had reduced sptz/mm². Progeny live performance was not affected by breeder's age. Breeders with 270 days retain fertility; however, their egg production, weight and hatchability of fertilized eggs is reduced. In conclusion, European quail breeders with 140 days of age have better egg quality, hatching and breeding results.
