“…In the present study, we found a total lipid content of 33%, similar to those reported in other studies on different genotypes of laying hens [7,36]. The cholesterol content found in the present work (9.7 mg/g of yolk) was similar to the values found by Raceviči ūt ė-Stupelien ė et al [7] on Lohmann Brown Classic line laying hens, ranging from 8.43 to 8.96 mg/g yolk. Conversely, quite high values were found by Tomaszewska et al [31] in Bovans Brown laying hens at 60 weeks (11.73 ± 0.17 mg/g yolk) and by Zemkovà et al [37] in ISA brown laying hens (ranging from 11.2 to 16.1 mg/g yolk).…”

“…Based on the above, various nutritional attempts have been conducted to reduce the content of cholesterol and modify the fatty acid profile to obtain n-3 PUFA-enriched eggs [31][32][33][34][35]. In the present study, we found a total lipid content of 33%, similar to those reported in other studies on different genotypes of laying hens [7,36]. The cholesterol content found in the present work (9.7 mg/g of yolk) was similar to the values found by Raceviči ūt ė-Stupelien ė et al [7] on Lohmann Brown Classic line laying hens, ranging from 8.43 to 8.96 mg/g yolk.…”

“…Similarly, Sokołowicz et al [38] did not find any significant effect of the production system on egg yolk cholesterol content in native Greenleg Partridge hens (Z-11), Rhode Island Red, or Hy-line Brown commercial hens from litter barn, free-range, and organic systems. Raceviči ūt ė-Stupelien ė et al [7] did not find any effect of the production system (cage and barn) or age (28,38, and 48 weeks of age) on cholesterol content in Lohmann Brown Classic line-laying hens. Conversely, Zemková et al [37] found that the housing system and the age of hens had a significant effect on both yolk and egg cholesterol concentrations, which were lower in eggs from enriched cages compared with those from a litter system; age had a fluctuating effect on cholesterol content, which decreased from 50 to 59 weeks followed by an increase at 68 weeks and, thereafter (at 75 weeks), a decrease.…”

“…The internal and external qualities of eggs can be influenced by various factors, e.g., the hen's genetic type, laying hen age, feeding strategy, and animal welfare; the latter is linked to the production system [3,6]. In recent years, there has been a growing interest among consumers to better understand the relationship between the production system, animal welfare benefits, and higher-quality egg production [7].…”

In recent years, the free-range system for laying hens has increased, driven by societal sensitivity to animal welfare. This study aimed to comparatively analyze the total lipid, cholesterol, and fatty acid composition of egg yolks of late-age laying hens reared in enriched cages (C) and the free-range system (FR). Eggs were collected from Lohmann Brown Classic hens at the 68th, 70th, 72nd, and 74th week of age. The concentrations of total lipids and cholesterol were not affected (p > 0.05) by either factor. Egg yolk from the FR group showed lower (p < 0.01) monounsaturated fatty acids and higher (p < 0.01) polyunsaturated fatty acid (PUFA) compared with that of the C group. From a nutritional point of view, the PUFA n-6/n-3 and the PUFA/SFA ratios of egg yolk from the FR group were favorably lower and higher (p < 0.01) compared with the C one. Conversely, hen age did not affect (p > 0.05) the fatty acid composition of yolks. Interactions between factors were found for total n-3 and n-6 PUFA and the n-6/n-3 ratio (p < 0.01), as well as the thrombogenic index (p < 0.05). In conclusion, the results confirmed that the free-range system may improve the nutritional yolk fatty acid profile and its positive impact on human health.

“…The quality of eggs could be affected by multiple internal and external factors such as genes, nutritional aspects, age of hens, management, and housing systems [ 24 , 25 , 29 ]. In this study, eggs from hens housed in a CC collected at the 20th to 26th wks were heavier than those in the CF system.…”

Egg consumers worldwide have increased their concerns about laying hens’ welfare and its impact on final egg product quality. This study compared the egg quality parameters under the conventional cage (CC) and cage-free (CF) egg production systems in the tropics. The study was conducted on a commercial farm in Colombia using Hy-Line Brown pullets, reared under the same conditions for the first 15 wks. At 16 wks, the hens were distributed into two housing systems, CC and CF, on the same farm. The hens were fed the same diet for each phase in both systems and feed intake varied slightly. Egg samples were collected every six wks, from 22 to 82 wks of age. A total of 3960 eggs were analyzed at 11 sampling times. Parameters such as albumen height, egg weight, yolk color, eggshell thickness, eggshell strength, and Haugh units were determined using a DET-6000 machine. At 22 and 82 wks, screening for Salmonella spp. status was conducted using environmental and egg samples. Additionally, at 34, 64, and 82 wks, yolk samples were obtained for fatty acid profiles and crude protein (CP) analysis. The data were analyzed in a completely randomized block design with repeated measures (11 times): mean separation by Student’s t-test yolk pigmentation, Haugh Units, and albumen height (p < 0.001) were higher in the CF compared with the CC between 38 and 69 wks of age, and eggs at 63 and 82 wks (p < 0.05) were heavier in the CF compared to the CC. Likewise, eggs from the CC had better eggshell strength from 57 to 82 wks. In the egg yolk fatty acid profile at the 34th wk, the pentadecanoic, palmitic, and heptadecanoic acids had higher concentrations in the CF systems than the CC. At the 64th wk, the egg yolk fatty acids—lauric, myristic, and heptadecanoic—had higher concentrations in the CF; likewise, at the 82nd wk, egg yolks from the CC had higher concentrations of lauric, heptadecanoic, and nervonic fatty acids than the CF. The eggs and environmental samples were negative for Salmonella spp. throughout the whole production phase. These results indicated that the production system might impact internal and external egg quality measures, potentially due to various stressors, including environmental factors or behavior restrictions.
