“…The amount of water lost by evaporation from hatching eggs was affected by both the length of the storage period and laying season (Stępińska, Mróz, Krawczyk, Otowski, & Górska, 2017). The detrimental effect of long-term storage was more pronounced in eggs from old breeder flocks (Kirket al, 1980;Meijerhof, 1994), which is probably the result of lower albumen quality at oviposition and a subsequent increased rate of decline during storage (Lapaõ et al, 1999).…”

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 flocks than in older flocks. For example, albumen pH increased more after 8 days of storage in younger flocks than in older flocks. Additionally, the embryonic morphological stage appears to increase as well with storage duration, but this increase is again more pronounced in younger flocks than in older flocks. Short storage (<7 days) seems to increase hatchability of eggs from young breeders, probably as a result of albumen liquefaction with consequently better oxygen availability for the embryo. However, long storage (>7 days) resulted in a decline in hatchability, which was stronger in older breeders than in younger breeders. Prolonged storage duration resulted in lower chicken quality in both young and old breeders, but interaction between storage duration and breeder age on multiple chicken quality parameters is not clear. Based on this review, it can be concluded that (a) Short storage can improve hatchability of eggs from young breeders, but not from older breeders. (b) Negative impact of long storage appears to be lower with young breeders than with old breeders. (c) Adapted storage conditions related to the age of breeders might be an option to reduce negative effects of prolonged storage on hatching egg quality and chicken quality.

“…Significant interactions between egg storage duration and breeder age have been observed as well, both on egg characteristics [ 18 , 22 ] and embryonic development [ 4 , 14 , 23 ]. The latter two studies reported that the decrease in embryonic growth rate, embryonic viability, and hatchability with prolonged storage duration was more pronounced with older breeders than in young breeders (59 vs. 32 weeks).…”

Egg storage duration and breeder age are probably interacting to influence egg quality, hatchability, and hatchling quality. To evaluate this interaction, the impact of breeder age (31, 42, 66 weeks) and storage duration (2, 5, 12, 19 days) was investigated on broiler breeder eggs (Arbor Acres). Thick albumen diameter and pH increased, and yolk dry matter decreased between 2 and 19 days of storage. With the increase of breeder age from 31 to 66 weeks, albumen height, percentage and dry matter and shell percentage decreased and the egg weight and yolk percentage, dry matter and diameter increased. Prolonged egg storage increased the yolk pH in all breeder ages, but earlier and steeper in the oldest breeders. Prolonged egg storage resulted in a lower hatchability of set and fertile eggs due to a higher percentage of embryonic mortality. Early mortality increased earlier and steeper with prolonged egg storage in the oldest compared to younger breeders. Between 5 and 19 days of storage, yolk free body mass, liver and proventriculus + gizzard percentages decreased, as well as hatchling length and yolk efficiency (yolk absorption per initial yolk weight). The latter effects were most pronounced in the younger than in the older breeders. Therefore, eggs are preferably stored shorter than 7 d, but if long storage (≥12 days) cannot be avoided, we recommend to store eggs of older breeders when egg quality and hatchability are most important. In case hatchling quality is most important, it would be better to store eggs of younger breeders (31 weeks) for a prolonged period.

“…However, when eggs of the same breed and breeder age are heavier, this is mainly due to an increase in the amount of albumen ( Everaert et al, 2008 ), resulting in a proportional decrease in yolk weight and an increase in albumen weight with egg weight ( Ho et al, 2011 ). Other researchers ( Stępińska et al, 2017 ) reported that the nutritional value of eggs decreased with hen's age, along with a deterioration in reproductive performance. The above findings indicate that the total protein content of the yolk and albumen decreases during the laying season.…”
