ABSTRACT
The objective of this study was to evaluate the effect of storage time on albumen quality, incubation yield, and hatch window in Pekin ducks (Anas boschas). A total of 1302 eggs were randomly distributed to seven treatments according to the storage time with durations ranging from 1 to 14 days. Each treatment consisted of 186 eggs with a two-day storage interval between treatments. The pH and Haugh unit (HU) of the albumen, egg weight loss during incubation (WL), hatchability (HTCH), incubation duration (ID), hatch window, asymmetry (ASS), percentile kurtosis (PK), and embryonic mortality were analyzed. A linear effect was observed forthe WL, ID, and PK and a quadratic effect forpH, HU, and HTCH over time. No significant effect of storage time was observed on ASS. Post-pipping embryonic mortality was linearly affected by storage time. Prolonging the storage period above 10 days reduces albumen quality and hatchability, delays the hatch of Pekins, and results in a higher percentage of post-pipping mortality.
