This study was conducted in order to evaluate the effects of two rearing systems (enriched cage and alternative systems) on the egg quality of laying hens and the influence of three environmental conditions. The experiment was conducted during three experimental periods of 28 days each. The 36 Dekalb White breed was used in each rearing system, with 27 weeks of age, respectively. Quality of eggs produced was evaluated in a completely randomized design 2x6 (two rearing systems and six replicates) at 20 ºC, 26 ºC and 32 ºC, and relative humidity of 60% in a controlled environment. For the analysis of egg quality the factors evaluated were egg weight, Haugh unit, specific gravity, yolk and egg white pH. There were no major differences in egg quality among the rearing systems, except for pH of egg yolk and white. It is concluded that the rearing system in the enriched cage and alternative system present no major differences in the quality of eggs combined with environmental conditions.Downloads
