Abstract: Prolonged hatching egg storage (>7 days) influences internal egg quality and embryo survival during both storage and subsequent incubation. Moreover, effects of storage of hatching eggs interact with the breeder age. The aim of this review was to investigate how this interaction between storage duration and breeder age affects egg, embryo, hatchling and chicken characteristics. Prolonged storage resulted in a reduction in egg quality in both young and old breeders. This reduction was more pronounced in young f… Show more

“…The greatest mortality rate was found in the chicks with 21 days of storage. Similar to the results of the present study, many studies in the literature report poorer vitality depending on prolonged storage time (Fasenko et al, 1992;Altan et al, 2002;Nasri et al, 2020).…”

“…Decreased hatchability leads to significant economic losses. In some studies, embryo development was negatively affected, abnormal embryo formation occurred, late-period deaths increased and hatching efficiency decreased in cases of storage for longer than 8-10 days (Altan et al, 2002;Schmidt et al, 2009;Nasri et al, 2020). However, the storage time may exceed one week depending on the market demand and the capacity of the incubator in hatching farms.…”

“…The differences in negative effects of prolonged egg storage with breeder age are probably related to changes in the embryo (e.g., number of viable cells) or egg characteristics (e.g., albumen pH and viscosity, shell quality), or in both of them [ 25 , 26 ]. As shown above, the interaction between storage duration and breeder age varies between studies; for review see Nasri et al [ 27 ]. Additionally, in most studies only a limited number of breeder ages and storage durations were included.…”

“…The results in our study indicated that the chick weight was decreased by long-term egg storage, which may be due to the reduced embryonic metabolism and growth, and organ development during incubation [4]. Previous studies showed inconsistent effects of long-term egg storage on fertility [6,9,24,35].…”

“…The egg storage duration mainly depends on the hatchery capacity and the variable market demand of newly hatched chicks. Generally, the hatchability is not problematic when eggs are stored for less than 7 days [1][2][3][4]. However, egg storage times beyond 7 days is shown to increase the mortality of embryos, and decrease the hatchability [1][2][3]5,6] and quality of newly hatched chicks [6,7].…”
