“…Golden quail had higher live weight from the beginning of the trial and higher live weight gain at the end of trial. Numerous researchers reported that different PC significantly affected the live weight (Oguz and Minvielle, 2001;Genchev et al, 2008;Tarhyel et al, 2012;Inci et al, 2015). Addition of GS to ration did not affect the live weight gain in the study.…”

“…When feed intake was examined at the end of the trial, it was observed that golden quail consumed significantly greater amounts of feed than grey quail; however, feed efficiency did not change between the two groups. In the study conducted by Inci et al (2015) with quail, they reported that feed intake was higher in golden quail, but feed efficiency did not change. Addition of GS (expecially the 20 g/kg group) to ration significantly increased feed intake particularly in grey quail compared with the goden group, but feed efficiency did not change in the present study.…”

The objective of this study was to determine the effects of grape seed (GS) supplementation to basal diet on performance, carcass characteristics, some biochemical parameters, and antioxidant status of tissues of Japanese quail in growth phase with different plumage colors exposed to heat stress (HS). A total of 144 eight-day-old Japanese quail including 72 (36 females, 36 males) grey and 72 (36 females, 36 males) golden were used in this study. The quail were kept under HS (16 h at 34 ºC, 8h at 22 ºC) and thermo-neutral (24 h at 22ºC) conditions between 15 and 43 days of age. All quail were fed a basal diet (control) and basal diet supplemented with GS at both 10 g/kg and 20 g/kg ratios. Each feeding treatment was repeated three times including four quail (two females and two males) per replicate. Heat stress considerably decreased the live weight gain on days 29-36, 36-43, and 15-43. Golden quail had higher live weight from the beginning of the trial. The increase of live weight on days 15-43 was higher in the golden group than in the grey group. Malondialdehyde (MDA) levels of liver and kidney tissues increased in heat-stress group compared with thermo-neutral group (P<0.001). In HS, significant increases were determined only in catalase (CAT) in the liver and in glutathione peroxidase (GSH-Px), CAT, and glutathione (GSH) in the kidney (P<0.05). Addition of dietary GS decreased MDA and antioxidant levels, which increased in liver and kidney of quail during HS. Plasma total cholesterol, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels were higher in quail under HS. Plasma total cholesterol, glucose, triglyceride, AST, and ALT levels of quail under HS decreased due to addition of 10 g/kg GS.

“…The same trend was at BW1, and BW2, where significant differences (P≥0.01) were found between them for both BW1 (31.70± 0.64, 34.5± 0.79) and BW2 (72.70± 1.29, 78.80± 1.58) for Br and Gd color, respectively (Table 2). Likewise, Inci et al (2015) found significant differences between dark brown and golden color groups (55.8±1.5, 60.6±1.4, respectively). At the 6 th week of age (BW6), there was an interaction effect between the plumagecolor type and sex where the females of the Br were highest weight (226.92± 3.75) compared to others (P≥0.05).…”

“…These findings were dissimilar with Nasr et al (2017) where the lowest body weight (174.68 g) was obtained for brown when they compared between four types of plumage-colors (white, golden, gray and brown). In addition, Inci et al (2015) found different direction where the females of both dark brown and golden was highest than males (P≥0.05). Interestingly, the live body weight of Br type at BW5 was heavier (195.0 ± 1.99) than those obtained in different study (131.94±3.75) (Eissa et al 2014).…”

Two plumage-color types of Japanese quail were used to compare the meat production potentialities using five selective microsatellite markers. A total number of birds was 189 for the two plumage-colors of quail [(Brown 114; 49 males, and 65 females), and (Golden 75; 42 males, and 33 females)], were used. Phenotypic data were live body weight at day1 (BW0) and measured weekly till the end of six' weeks of age (BW6). The weight gain was calculated for intervals. The analysis of variance for live body weight at different age's data revealed that there was a highly significant difference on BW between plumage-color types (Br, and Gd) at the day1 of age (P≥0.001). At the 6 th week of age (BW6), there was an interaction effect between the plumage-color type and sex where the females of the Br were highest weight (226.92± 3.75) compared to others (P≥0.05). Considering the weight gain trait, the results revealed that the plumage-color type had significant effect (P≥0.05) on weight gain at the early age (from day1 to the end of the 1 st week, WG0-1), and WG1-2. On molecular technique basis, a total of twenty alleles were discovered across the two types of quails. The average of alleles per locus over loci and plumage-color types was 3.30 ±0.15 alleles. Only one private allele at 170bp with allele frequency 0.06 was present in Br for the locus GUJ0029. The polymorphic information content (PIC) average is 0.46 with the values ranging from 0.34 at locus GUJ0063 to 0.61 at locus GUJ0023. In addition, the inter-population genetic differentiation coefficient (GST) ranged from 0.0 of locus GUJ0077 to 0.077 of locus GUJ0029, and the inter-population genetic variation accounted for 3.6% of the total genetic variation. The variance among, and within individuals was observed as 93% and 7% of respectively by using AMOVA. Moreover, the Hardy-Weinberg equilibrium among the five loci was assessed. In spite of the fact that GUJ0077 locus was an exceptionally significant (P≥0.001) for Gd, it was not for Br. In like manner, the GUJ0059 locus was significant (P≥0.05) in Gd yet not in Br. Nevertheless, the general linear model analysis showed significant association in Gd between the locus GUJ0063 not only with live body weight at BW0 (P≥ 0.05), but with gain weight at W2, and W4 also (P≥ 0.05). Whereas, in Br type, the locus GUJ0029 was associated with BW5 (P≥ 0.01) and BW6 (P≥ 0.05). In addition, the same locus associated with weight gain at W1 (P≥ 0.05), and W2 (P≥ 0.01). Which exposed that both of GUJ0029, and GUJ0063 loci linked with the gene(s) that responsible regulator for quails' live body weight. In conclusion, these findings of this study confirm that the association between plumage-color and productive traits have prevailed and sanctioned by using the molecular markers.

“…The color factor had much more contribution (100% normalized importance) in the construction of the classification tree diagram compared with other egg quality characteristics in the study. As in fattening performance, carcass, and egg quality characteristics (Inci et al, 2015), the fertility of the quail eggs should be considered in respect to different feather colors. The knowledge may be profitable for further relevant studies due to economic factors.…”

-The objective of this study was to determine the effects of egg quality characteristics (egg weight, egg width, egg height, and shape index) on fertility of eggs of Japanese quail with different colored feathers (yellow, white, grizzled, and normal), which are of economic importance for poultry production. For this purpose, 383 eggs of Japanese quail with various feather colors were used. In the study, usability of classification and regression tree (CART) data-mining algorithm as a classification tree method is necessary for poultry breeders to define proper cut-off values of egg quality characteristics that ensure Japanese quail eggs at good quality in fertility. Fertility as the dependent variable in the study was examined as a binary trait (fertile and infertile) and all the egg quality traits accepted as explanatory variables were continuous variables. Feather color was also included as a nominal categorical explanatory variable. The classification tree results showed that the highest fertility ratio of 90.9% was obtained from the eggs of Japanese quail of white, grizzled, and normal feather colors with 10.425 g ≥ egg weight, 24.565 mm ≥ egg width, or the fertility ratio of 88.2% of the eggs was observed with 10.425 g ≤ egg weight and 25.605 mm ≥ egg width. Consequently, usability of the tree-based CART algorithm is important in practice for properly establishing fertilized eggs, depending on feather color types of Japanese quail.
