“…However, albumen pH was not affected by cage tier and can be used to measure egg freshness. Overall, albumen pH varied between 8.62 and 8.65, which is in agreement with data reported for ATAK-S laying hens by Sekeroglu et al (2010) and Yıldırım et al (2013;2014). The ∆E* values of the eggshell in each tier indicated a high uniformity of eggshell pigmentation.…”

“…The eggs were analysed for interior and exterior quality traits, weight, shell surface area, specific gravity, shape index, shell-breaking strength, shell weight, thickness, albumen index, yolk index, Haugh unit (HU) score and albumen pH (Nordstrom & Ousterhout, 1982;Anderson et al, 2004;TSE, 2009;Sekeroglu et al, 2010). Egg specific gravity was determined with graded salt solutions ranging from 1.069 g/cm 3 to 1.099 g/cm 3 with gradations of 0.003 g/cm , as described by Hamilton (1982).…”

This study was conducted to investigate the effects of cage tier and age on performance characteristics of layer hybrids, egg quality and some stress parameters. Ninety laying hens (hybrid ATAK-S) of similar bodyweights were used in the experiment. They were housed in three-tier conventional battery cages (bottom, middle and top) with 600 cm 2 /per bird. The experiment was conducted on hens from the age of 18 weeks to 42 weeks. Layers at the age of 18 weeks were randomly allocated to conventional three-tier battery cages with five replicates of six hens per treatment in a completely randomized design. In the bottom, middle and top tiers, 5% age of yield was observed as 151, 146 and 156 days, respectively; 50% age of yield was 162.4, 158.6 and 161.8 days; 5% yield age bodyweight (BW) as 1597.8, 1460.5 and 1599.2 g; 50% yield age BW as 1708.7, 1666.4 and 1671.7 g, respectively. The effects of cage tiers on week 42 BW, feed conversion ratio (FCR), tonic immobility (TI), egg weight (EW), egg yield (EY), and most external and internal quality traits of the hens' eggs were found to be insignificant. Except for shape index (SI) and albumen pH, internal and external quality traits of eggs were significantly affected by age of the hens. In addition, there were significant effects of age on the FCR, EY, EW and oviposition time. The effects of cage tier on tonic immobility (TI) in week 42 and viability were found to be insignificant, but TI in week 30 was found to be significant. It can be concluded that cage tier did not have significant effects on egg yield, egg quality and indicators of stress parameters studied in the experiment. However, these parameters were affected by the age of the hens at the beginning of the laying period. ______________________________________________________________________________________

“…No difference in yolk color might be the result of the use of the same feed and vegetation in the outdoor area of the free range as a result of decreased seasonal conditions. Similar to our results, Şekeroğlu et al (17) concluded that yolk color was not affected by the type of housing system. Previous studies reported increased hen age being associated with increased yolk weight, albumen weight, and yolk ratio (23), but decreased albumen ratio (24), eggshell quality (25), and shape index (4).…”

“…Samiullah et al (3) found that egg weight, Haugh unit, shell weight, shell ratio, and shell thickness values of eggs in a conventional-cage system were higher than those of eggs in a free-range system and, similar to our results, those values increased with flock age, except for Haugh unit, which decreased. However, in other studies there were no differences between housing systems for shell weight (14,16) and Haugh unit (17). In this study generally the temperature was low in the FR system depending on outdoor access and this might have contributed to albumen quality and Haugh unit value of eggs.…”

The material for the current research was obtained from 480 layers (Lohmann Brown) housed in conventional-cage (CC), enriched-cage (EC), and free-range (FR) production systems between 22 and 60 weeks of age. A total of 720 eggs were analyzed for external and internal egg quality traits.The three housing systems were located within the same research unit of Uludağ University. Two cage systems, CC and EC, were installed in a windowed and fan-ventilated cage hen house with both cage types in the same room. The FR system was located 120 m from the cage hen house.The CC system consisted of galvanized wire cages (50 × 45 × 45 cm) with a trough-type galvanized feeder, egg belt, manure belt, and nipple drinker. Each CC cage provided a total of 562.5 cm 2 floor area per hen.The EC system cages met the requirements of EU Directive 1999/74/EC. The EC system consisted of 2 tiers, and each tier consisted of 2 cages (4 EC cages). The EC

“…However, albumen pH is not affected by PGRE groups and can be used to measure egg freshness. Overall albumen pH ranged from 8.64 to 8.72, which is in agreement with previous data, such as 8.72 for Atak laying hens (Sekeroğlu et al, 2010) and 8.29 to 8.39 for 30-wk-old Dekalb white laying hens (Olobatoke & Mulugeta, 2011).…”

This study was conducted to determine the effect of Korean ginseng (Panax ginseng C.A. Meyer) root extract (PGRE) on egg production and egg quality characteristics of hens at the beginning of their laying period (20 weeks old). Four groups of commercial hens (Atak-S; Turkish native hybrid) were fed with diets containing 0 mg, 50 mg, 100 mg and 150 mg PGRE/kg. Experimental results indicated that dietary PGRE had no effect on feed intake, feed efficiency, egg mass (EM) or egg production parameters. Over 12 weeks, hen-day egg production (HDP) of the groups was 73.5%, 74.8%, 69.2% and 79.0%, respectively. The effect of different levels of PGRE on egg weight, shape index (SI), specific gravity, shell thickness, Haugh Unit (HU), yolk index (YI) and albumen index (AI) was not statistically significant during the entire experiment. Egg yolk colour was conspicuously lower in the 100 mg and 150 mg PGRE/kg groups than in the control. The L*, a* and b*, hue (H) and chroma (C*) values for eggshell colour were not significantly different among the groups, except for the colour difference (∆E*, (L 2 +a 2 +b 2 ) ½ ), where values in PGRE groups were higher than in the control group. The trolox equivalent antioxidant capacity (TEAC), ferric reducing antioxidant power (FRAP) and total phenolics concentration of PGRE were 598 ± 1.841 mmol trolox/kg, 15.45 ± 0.457 mmol TEAC/kg and 1.02 ± 0.03 g gallic acid equivalents (GAE)/kg, respectively. Serum glucose, cholesterol and triglyceride concentration were similar in the PGRE supplemented groups and the control. In conclusion, the dietary supplementation with PGRE did not affect the productivity performance traits and egg quality of hens at the beginning of the laying period.
