Adição de óleo de copaíba (copaifera langsdorffii) e sucupira (pterodon emarginatus) na alimentação de poedeiras: qualidade física de ovos armazenados em diferentes temperaturas. Ciência Animal Brasileira, Goiânia, v. 19, e41508, 2018. Disponível em: <https://www.revistas.ufg.br/vet/article/view/e-41508/25782>.e- 1809-6891http://repositorio.bc.ufg.br/handle/ri/15875The aim of this study was to evaluate the effects of the dietary supplementation of laying hens with natural oils on the quality of fresh eggs stored under refrigeration (R) and room temperature (RT). Hens were fed balanced corn-soybean diets supplemented with increasing levels of Copaifera langsdorffii (CP-0.03; 0.06 and 0.09%) or Pterodon emarginatus (SC-0.03 and 0.06%) oilresins plus a negative control (CN). Periodically, three eggs per treatments were evaluated for haugh unit (HU); yolk index (YI); yolk color (L*, a* e b*); yolk and albumen pH and percentages of shell (PS); albumen (PA) and yolk (PY). Statistical analysis was performed using a mixed model (SAS 9.3) and Tukey test. The supplementation of 0.06% CP and 0.03% SC preserved (p<0.05) HU in eggs stored in RT during 14 days, similarly to results found in R. In addition, dietary supplementation of natural oils helped to control pH levels in yolks during RT storage. In conclusion, the dietary supplementation of copaiba and sucupira showed positive effects on albumen quality and yolk pH for eggs stored at room temperature, however, no additional effect was found for eggs stored chilled.porAcesso AbertoAntioxidantes naturaisOvos armazenadosPoedeiras semipesadasQualidade físicaEgg qualityLaying hensNatural antioxidantsStorage assayArtigo10.1590/1809-6891v19e-41508
