Poultry Science 2007 86:953-958.).īesides, egg storage can prolong the incubation period, causing a delay in the hatching process ( Brake, 1997 Brake J, Walsh TJ, Benton CE, Petitte JN, Meijerhof R, Peñalva G. Conjugated linoleic acid and fish oil in laying hen diets:effects on egg fatty acids, thiobarbituric acid reactive substances, and tocopherols during storage. Poultry Science 2005 84:865-874.) and increases in lipid peroxidation as the egg storage time is increased may compromise embryo viability ( Cherian, 2007 Cherian G, Traber MG, Goeger MP, Leonard SW. Effects of supplementing broiler breeder diets with organic selenium and polyunsaturated fatty acids on egg quality during storage. Furthermore, during the storage, oxidation of proteins and lipids of yolk and albumen occurs ( Pappas, 2005 Pappas AC, Acamovic T, Sparks NHC, Surai PF, McDevitt RM. Journal of Animal and Feed Sciences 2001 10:267-272.) and cell death can occur when the embryo is exposed to a pH of 9 for long periods ( Reijrink, 2009 Reijrink I. The effect of storage on egg quality and fatty acid content in PUFA-enriched eggs. Silversides & Scott, 2001 Niemiec, 2001 Niemiec J, Stepínska M, Swierczewska E, Riedel J, Boruta A. The effect of storage and strain of hen on egg quality. This is because, during storage, the eggs lose water and carbon dioxide to the environment, resulting in an increase in pH from 7.6 to 9.0 ( Scott & Silversides, 2000 Scott TA, Silversides FG. Journal of Animal Physiology and Animal Nutrition2020 104:257-268.). Egg storage and breeder age impact on egg quality and embryo development. ![]() Fasenko, 2001a Fasenko, 2001b Fasenko, 2007 Nasri, 2020 Nasri H, van den Brand H, Najjar T, Bouzouaia M. Identification of the incubation period when broiler breeder embryonic development is delayed due to egg storage for 14 versus 4 days. Storage of chicken and turkey eggs for more than seven days alters the internal characteristics of the eggs, affects embryo development and survival, decreases hatchability, and reduces chick quality ( Fasenko & Robinson, 1998 Fasenko GM, Robinson FR. Effects of egg storage on hatchability, chick quality, performance and immunocompetence parameters of broiler chickens. Goliomytis, 2015 Goliomytis M, Tsipouzian AT, Hager-Theodorides L. Egg storage has become a common practice in commercial hatcheries, mainly due to the need to collect sufficient hatchable eggs that allows for uniformity and classification of eggs according to common characteristics, such as breeder age, batch, and sanitary state ( Reijrink, 2009 Reijrink I. Abd El-Hack, 2019 Abd El-Hack ME, Hurtado CB, Toro MDM, Alagawany EM, Abdelfattah EM, Elnesr SS. Effects of goose age and storage time of eggs. Pre-incubation storage time, environmental storage conditions, and breeder age are the most important factors in changing the internal characteristics of eggs ( Tilki & Inal, 2004 Tilki M, Inal S. Effects of short storage conditions and broiler breeder age on hatchability, hatching time, and chick weights. ![]() The quality of fertile eggs in the poultry production chain is essential for the incubation and production of quality chicks ( Tona, 2003 Tona K. 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.Īlbumen quality embryonic development hatchability storage of fertile eggs embryonic mortality Post-pipping embryonic mortality was linearly affected by storage time. No significant effect of storage time was observed on ASS. A linear effect was observed forthe WL, ID, and PK and a quadratic effect forpH, HU, and HTCH over time. 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. Each treatment consisted of 186 eggs with a two-day storage interval between treatments. A total of 1302 eggs were randomly distributed to seven treatments according to the storage time with durations ranging from 1 to 14 days. 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).
