| The present study was conducted to investigate the effects of storage duration and egg shell color on external and internal egg quality traits. Eggs were obtained from 29-week--old ATAK-S layer hybrids reared in a traditional cage system. Storage durations were set as 0, 7, 14, 21 and 28 days. Shell color was classified as dark (59.00-67.99); moderate (68.00-70.99) and light (71.00-79.99) using the ΔΕ values of the eggs. The storage duration significantly affected the egg weight (P≤0.01), specific gravity (P≤0.01), breaking strength (P≤0.01), shell thickness (P≤0.01), shell weight (P≤0.01), surface area (P≤0.01), albumen index (P≤0.01), yolk index (P≤0.01),... |
