摘要：
The present study was designed to study the effects of conventional and free range systems on egg quality attributes, fatty acid profile, and cholesterol contents of laying hen. Two hundred and forty R1 cross of Rhode Island Red (RIR) × Fyoumi (F) layers during the peak production were divided into two groups and reared in two different housing systems (free range vs. conventional systems). The statistical analysis of the results revealed that the housing system (modification of diet) significantly (p < 0.05) affected egg quality, fatty acid profile, and cholesterol contents. The highest (p < 0.05) whole egg and albumen weights were recorded for eggs produced in a conventional system and higher yolk weight and shell thickness were recorded in free range hens. Significantly (p < 0.05) lower concentration of saturated and higher concentration of mono- and polyunsaturated fatty acids were observed in eggs produced under a free range system. In addition, higher level of total omega-3 fatty acids and higher ratio of omega-6 to omega-3 fatty acids were observed in free range eggs as compared to those in the conventional system. From the results of the present study, we concluded that eggs produced from Rhode Island Red × Fyoumi laying hens in a free range system are qualitatively superior compared to those in the conventional system.
