Effects of transportation and storage duration of Japanese quail eggs on hatchability

Abstract

This study was conducted to investigate the effects of transportation from breeder's farm to hatchery, and of storage duration on the hatchability of quail eggs. Hatching eggs were divided into two groups. The first group was stored for seven days and the second for 14 days. Half of each group was subjected to 200 km transportation before initiation of embryonic development, and the other half was not transported. Relative weight loss ratios varied significantly with storage duration, but did not vary after transportation. Hatchability of fertile eggs varied with storage duration and transportation, but only the effects of storage x transportation were found to be significant. Embryonic mortality for the first period of 14-day storage (22.1%) was significantly higher than those stored for seven days. In the second period (days 10-16), embryonic mortality ratios varied significantly with storage and transportation. Transportation after 7-day storage influenced the hatchability of fertile eggs negatively, compared with non-transported eggs stored for seven days. On the other hand, transportation after long-term storage had a higher hatchability of the fertile eggs than the non-transported eggs stored for the long time. These findings suggest that the vibration through transportation over the secondary road after long-term storage influenced the embryonic development of hatching eggs positively. Thus, the discarded chick ratio of the long-term + transport group was lower than short-term + transport group, and improved the hatchability of fertile eggs.

“…This is in agreement with the reports of Goliomytis et al (2015) and Abioja et al (2020a) . However, Alsobayel et al (2013) reported a decrease in chick yield as length of storage increased from 0 to 14 d. However, Çopur Akpınar and Günenç (2019) discovered that chick yield in Japanese quail was not affected by storage length.…”

Effect of storage duration on egg quality, embryo mortality and hatching traits in Transylvanian naked neck chickens under humid tropical conditions

“…Many authors had confirmed that hatchability is lowered by extended storage of chicken eggs (Petek & Dikmen, 2006;Khan et al, 2014;Abioja et al, 2021), especially in older breeder hens (Tona et al, 2004). A similar report was obtained in studies with quail eggs (Mani et al, 2008;Romao et al, 2008;Çopur Akpınar & Günenç, 2019). The report in a study had stated that hatchable eggs stored for more than 10-14d would have a decline in egg hatchability (King'ori, 2011).…”

“…The report in a study had stated that hatchable eggs stored for more than 10-14d would have a decline in egg hatchability (King'ori, 2011). There was a significant difference in hatchability of nontransported Japanese quail eggs stored for 7 or 14d (Çopur Akpınar & Günenç, 2019). There was also a negative relationship between hatchability and egg storage duration (R 2 = 0.53).…”

Quality of Japanese quail eggs according to different storage periods and temperatures

“…With prolonged storage, egg weight loss rates increase, albumen becomes less viscous due to chemical reactions related to moisture and CO 2 loss, causing height reduction, alkalinity increase and palatability loss. According to Akpınar and Günenç (2019), quail eggs can preserve quality attributes at room temperature for storage periods of less than four days. Thus, we hypothesized that the storage of quail eggs under refrigeration reduces the deterioration rate and the eggs can be stored for periods of up to 30 days, under these conditions, without losing internal quality.…”
