The effect of storage periods and SPIDES on embryonic mortality, hatching characteristics, and quality of newly hatched chicks in broiler eggs

Abstract

AbstractsEgg storage duration can affect embryo mortality, hatching characteristics, hatching time, and post-hatch chick quality. In order to assess these effects, the impact of storage duration (5 days, 10 days, 15 days) and short incubation period during egg storage (SPIDES) investigated further 18, 900 eggs of broiler breeder (ROSS 308) in 3 × 2 factorial arrangement design. In the SPIDES treatment, the egg shell temperature was raised from its storage temperature (18 °C) and held at 100 °F for 3.5 h. Storage periods could significantly (P < 0.05) influence on embryo mortality (total, early, middle, and late), hatchability of both the total eggs and fertile eggs. The SPIDES treatment had a significant (P < 0.05) impact on a lower embryonic death rate and improved egg hatchability. Eggs stored for 5 days and eggs treated with SPIDES significantly (P < 0.001) shorten hatching time, batch’s 90% hatching time (T 90% H), mean hatching time (MHT), maximal hatching period (MHP), and hatching window (HW). Chick quality was also determined, whereas storing eggs for 5 days and using the SPIDES treatment resulted in enhanced (P < 0.001) chick weight relative to egg weight (CW/EW), activity (AC), and chick quality score (CQS). The residual yolk sac weight (RYSW), unhealed navel (UHN %), and dirty feather (DF%) recorded the lowest (P < 0.001) values compared to long storage periods and control group. Finally, stored for 5 days treated by SPIDES positively affected the hatchability characteristics, the shortening hatching time, and the quality of chicks. Regarding the results, it was confirmed that using the SPIDES treatment to prevent the harmful effects of broiler eggs being stored for an extended period of time is a viable option.

Breed Of Chicken And Frequent Short Periods Of Incubation During Different Egg Storage Periods (SPIDES) Differentially Modify The Hatchability %, Chick’s Quality And Post-Hatching Bird’s Performance

“…These findings agreed with the previous reports of Okasha et al [26] who reported reduction in hatchability % for eggs stored for long period (15 days). They ascribed the low hatchability % following the long storage to increasing embryonic death with the long-term egg preservation.…”

“…The high body weights following the long term egg preservation agreed with the findings of Nowaczewski et al [25] which recorded increases of chicks' body weights following the long term egg storage. Again, decreasing the chicks hatching weights following the application of SPIDES may be linked with increasing water loss during long term storage [26]. Also, the heavy weights in the case of Avian-34 compared to Fayoumi were perhaps correlated to the differences in egg weight between the two breeds hence there is a positive correlation between egg weight and chick's weight.…”

“…These findings were in agreement with the results of Ebeid et al [37] which stated a decline in the chick quality following the long term egg preservation (for up to 14 days). On the other hand, an improved chick quality was observed for chicks emerged from egg subjected to frequent periods of SPIDES during storage [26,28]. Though, Reijrink et al, 2010 [38] did not prove improving the chick quality following pre-storage incubation.…”

Effect of thermal manipulation on embryonic development, hatching process, and chick quality under heat-stress conditions

“…Egg weight loss is a quantitative trait that is affected not only by the eggshell characteristics and hen genotype (strain), but also by surrounding environmental conditions (such as temperature and RH), as well as the egg management (such as the preincubation egg storage) ( Khalil et al, 2016 ; Grochowska et al, 2019 ; Okasha et al, 2023 ). The proportion of egg weight loss is crucial for ensuring enough air cell size inside the egg for proper lung function and chick pipping ( Ar and Rahn, 1980 ).…”
