DIETARY SUPPLEMENTATION WITH PLANT OILS FROM COPAÍBA (Copaifera langsdorffii) AND SUCUPIRA (Pterodon emarginatus): QUALITY OF PHYSICAL ASPECTS OF EGGS STORED UNDER DIFFERENT TEMPERATURES

Abstract The 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 ® 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
