“…The average egg weight in this study was 12.76 g (Table 1), which was lower than the 13.40 g reported by Khaldari et al (2010) and 13.25 g reported by Copur et al (2010). On the other hand, this average value for EW is in agreement with those reported by Erensayin and Camci (2002), Sahin et al (2002), Roshdy et al (2010) and Lotfi et al (2012) of between 12.00 and 12.75 and also higher than the 10.27-11.43 g reported by Hassan et al (2003), Kul and Seker (2004), Mielenz et al (2006), Sezer (2007), Alkan et al (2010) and Al-Daraji et al (2010) for quails. Specific gravity (SG) measures the relative proportion of shell of the egg based on its density (Wolc et al, 2010).…”

“…External egg quality of poultry species exhibits high variation because egg formation and subsequent egg shell quality is a complex process that depends on several biomechanisms, which can be determined by both genetic and enviromental conditions such as species, strain, age of hen, feeding and management. The effects of selection, feeding and flock management on external egg quality of Japanese quail have been investigated previously (Minvielle, 1998;Minvielle and Oguz, 2002;Sahin et al, 2002;Kul and Seker, 2004;Al-Daraji et al, 2010;Alkan et al, 2010;Nowaczewski et al, 2010).…”

The objective of the present study was to estimate heritabilities as well as genetic and phenotypic correlations for egg weight, specific gravity, shape index, shell ratio, egg shell strength, egg length, egg width and shell weight in Japanese quail eggs. External egg quality traits were measured on 5864 eggs of 934 female quails from a dam line selected for two generations. Within the Bayesian framework, using Gibbs Sampling algorithm, a multivariate animal model was applied to estimate heritabilities and genetic correlations for external egg quality traits. The heritability estimates for external egg quality traits were moderate to high and ranged from 0.29 to 0.81. The heritability estimates for egg and shell weight of 0.81 and 0.76 were fairly high. The genetic and phenotypic correlations between egg shell strength with specific gravity, shell ratio and shell weight ranging from 0.55 to 0.79 were relatively high. It can be concluded that it is possible to determine egg shell quality using the egg specific gravity values utilizing its high heritability and fairly high positive correlation with most of the egg shell quality traits. As a result, egg specific gravity may be the choice of selection criterion rather than other external egg traits for genetic improvement of egg shell quality in Japanese quails.

“…as the source of longerchain n-3 PUFAs, namely EPA, DPA and DHA. Earlier studies proved positive impact of flaxseed in the diet of laying quails on such egg quality criteria as egg weight, yolk diameter, albumen height, shell thickness, Haugh unit, albumen percentage and albumen weight (Al-Daraji et al, 2010). On the other hand, the replacement of fish oils by microalgae as the source of longer-chain n-3 PUFAs is the interesting alternative because of some undesirable effects on the sensory qualities of eggs occurring at the inclusion levels even at above 1.5% of fish oil in the diet of laying birds (Gonzalez-Esquerra & Leeson, 2000).…”

Summary The influence of feed supplemented with dietary sources of n‐3 polyunsaturated fatty acids (PUFAs), namely flaxseed and algae Schizochytrium sp., on the fatty acid composition of lipids from Japanese quail eggs was studied. Two groups of quails were fed for 19 weeks, starting from 6th week of life. Lipid fractions from dried egg mass of total of 4300 eggs of control and experimental group were analysed. The fatty acid profile was affected in both triacylglycerols and phospholipids. The significant (P < 0.05) increase in n‐3 PUFAs up to 7.33% in the total lipids, α‐linolenic acid (ALA, 18:3) up to 4.57% in triacylglycerols, docosahexaenoic acid (22:6, DHA) up to 23.91% in phosphatidylethanolamine and up to 4.35% in phosphatidylcholine as well as the significant (P < 0.05) reduction in n‐6/n‐3 ratio in the lipid fractions to the range of 0.9–3.7 was observed in experimental group. The incorporation of different n‐3 into lipids was selective: ALA was found in the triacylglycerol fraction, whereas EPA, DPA and DHA were detected in the phospholipid fractions, exclusively at sn‐2 position. The studies showed that the feeding quails with modified diets is effective way of biofortifying the eggs with nutritionally desired n‐3 PUFAs.

“…Protein with animal source such as eggs are of a major significance for balanced and adequate human nutrition and health (Al-Daraji et al, 2010). Recently, antibiotics have been used as growth promoters for higher yields in poultry production (Sinar et al, 2013;Mehdi et al, 2018).…”

The current study was conducted to examine the influences of Sargassam cristafolium, Gracilaria pulvinata, Rhus coriaria, and Punica granatum peel dried powder in two levels (10 and 20gr/kg) of dietary on productive performance and some egg quality characteristics of laying Japanese quail. A total of 675 (49 days old) Japanese quail were randomly distributed into nine groups with three replicates of 25 birds in each. Results showed that egg weight, shell weight, albumen weight and shell thickness were not influenced by treatments. The effects of medicinal plants on weekly egg production differ depending on the dietary medicinal plant type and dosage. Moreover, the birds fed diet supplemented with Sargassum cristaefolium at 10g/kg had greater weekly egg production compared to others. Haugh unit was reduced by diet supplemented with R. coriaria. Diet supplemented with S. cristaefolium at 20 g/kg increased yolk weight. Furthermore, greater albumen protein and thiobarbituric acid content of the tenth day's eggs (TBAd 10 ) were perceived in birds fed diet supplemented with G. pulvinata. In present study, the lowest levels of cholesterol (9.66 mg/g) was determined in the egg yolk of groups R. coriaria and G. pulvinata, and the control group showed to have the most amounts (12.00 mg/g). Based on obtained data, addition of 0.5% and 2% of S. cristafolium, G. pulvinata, R. coriaria, and P. granatum peel to the diet lead to be progress in egg production rate, enhanced the egg quality and egg biochemical properties in Japanese quail.
