ABS4566: Influence of different storage temperature and duration on incubation traits, hatching performance and embryonic development in chukar partridge eggs
Abstract. The purpose of this study was to investigate egg traits during incubation, hatching performance and embryonic mortality of chukar partridge eggs under different storage duration and temperature conditions. A total of 640 eggs were allocated to equal two batches and stored for 7 and 14 days. The equal number of eggs for each storage time group were stored in 4 chambers with different temperatures (3, 9, 15 and 21 °C). After storage, 30 eggs from each subgroup were examined to determine stage of blastoderm development. The remaining eggs (50 eggs from each subgroup) were set into the same incubator and transferred to hatcher set on 21st day. All egg weight parameters (initial, before incubation, transfer), hatch weight and hatching parameters were recorded. The results indicated that weight loss during storage increases with extended duration, particularly above 9°C. Storage time didn’t significantly affect hatch weight. Incubation periods were significantly longer for the eggs stored for 14 days compared the those stored for 7 days. Significant interactions between storage duration and temperature were noted for hatch weight and incubation time. Even though blastoderm development of the eggs stored at 21 °C were significantly at higher stages compared to other groups, almost all eggs from the treatment groups were below at gastrula stage. Mid-term embryonic mortality rate was significantly higher for the eggs stored at 21 °C and 7 days. The results suggested that chukar partridge eggs can be stored at temperature ranges from 3 °C to 21 °C without any significant negative effects. In the light of these results; further investigation into the effects of various storage temperatures under long-term storage period, particularly more than 21 days, is recommended to improve storage conditions and optimize hatching results in partridge eggs.
