Resumo: 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.

O experimento foi conduzido durante três períodos experimentais de 28 dias. Foram utilizadas 36 aves da linhagem Dekalb White em cada sistema de criação com 27 semanas de idade, respectivamente. Avaliou-se a qualidade dos ovos produzidos em um delineamento inteiramente casualizado 2x6 (dois sistemas de criação e seis repetições) com temperaturas de 20 ºC, 26 ºC e 32 ºC e umidade relativa de 60% em ambiente controlado. Para a análise da qualidade dos ovos foram avaliados o peso dos ovos, a unidade de haugh, a gravidade específica, pH da clara e da gema. Não foram observadas grandes diferenças na qualidade dos ovos entre os sistema de criação, exceto no pH da gema e da clara. Conclui-se que o sistema de criação em gaiola enriquecida e no sistema alternativo não apresentou grandes diferenças quanto á qualidade dos ovos combinadas com as condições ambientais.Universidade Federal de Viçosa - UFV2013-08-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/32310.13083/reveng.v21i4.357Engineering in Agriculture; Vol. 21 No. 4 (2013); 334-339Revista Engenharia na Agricultura - REVENG; v. 21 n. 4 (2013); 334-3392175-68131414-398410.13083/reveng.v21i4reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/323/243Camerini, Nerandi LuizOliveira, Daniele Lopes deSilva, Rafael CostaNascimento, José Wallace BArbosaFurtado, Dermeval Araujoinfo:eu-repo/semantics/openAccess2023-01-19T13:16:40Zoai:ojs.periodicos.ufv.br:article/323Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:16:40Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
