This study investigated the effects of pre-storage heating and storage period of hatching eggs on hatchability traits and chick quality of Dokki-4 (Egyptian local strain of chickens) laying hens. A total of 3600 eggs were collected from 46-week-old laying hens. Eggs were distributed in a 3x4 factorial arrangement, with three storage times (4, 8 and 12 days at 18°C and 75% RH) and four heat treatments prior to storage (0, 3, 6 and 9 hours at 37.5°C and 56% RH). Eggs were distributed to twelve treatments of 20 replicates. After storage, eggs were incubated under the normal conditions of incubation at the same time. The results showed that the long storage period increased egg weight loss. Hatchability and chick quality results from 8-12 days stored eggs were lower than eggs stored for 4 days. The 6-hour pre-storage heating system substantially improved egg hatchability and chick quality relative to non-heated or 9-hour heating. Important interactions were observed during pre-storage heating × egg storage time for loss in egg weight, hatchability of total and fertile eggs, embryonic mortality and chick quality. When eggs were stored for more than four days, pre-storage heating of hatching eggs for six hours improved hatchability and chick quality compared to unheated eggs or heated for 9 hours. Conclusively, pre-storage heat treatment beneficially affects hatchability traits and chick quality, especially when hatching eggs are stored for long periods.

The Relationship

Experiments were conducted to determine the effect of genotype, (reciprocal crosses), age of pullet (three consecutive 42-day periods) and egg storage treatment on the relationship of crushing strength to shell elasticity (the ability to recover from deformation and expressed as deformation per unit load), and to study the influence of storage treatment on crushing strength.Small but occasionally significant differences were noted among crosses and ages in the relationship of crushing strength to elasticity. Storage treatment exerted a much more marked effect on this relationship. The average increase in standard error of estimate incurred by pooling the raw data from all storage treatments was 15.0%, as compared with a maximum increase of 2.1% when the raw data for crosses or ages were pooled.Eggs stored in water, either intact or with the albumen and yolk removed, became progressively weaker throughout the 60-day storage period, as judged by a significant linear increase in elasticity. The strength of eggs stored at 21 °C in a normal or CO2 atmosphere and of those stored at 4 °C, with or without spray-oiling, underwent no significant change during storage.

Cells Death

The article analyzes the relationship between the level of blastoderm cells death during storage and the hatchability of eggs. Changes in the incubation parameters of eggs, the intensity of embryo development, the duration of the hatching period, the energy of chick's hatching depending on the period of egg storage were observed. It is known that when an egg is laid, the chicken embryo is represented by a multilayered blastoderm. During egg storage, the total number of blastoderm cells decreases, which further affects the viability of the embryo, the hatchability and chick quality. The aim of the study was to investigate the effect of the duration of egg storage period on blastoderm cells death and to establish the relationship between this indicator and the results of incubation. The work was carried out at State Poultry Research Station of NAAS on hatching eggs of red Rhode Island chickens. The study of the viability of blastoderm cells, the study of the intensity of embryo development, the duration of the hatching period, the energy of hatching were carried out in groups of eggs with storage period of 2 (control group), 10, 14, 17 and 21 days. It was found that with increasingof egg storage duration, there were significant decrease in the number of viable blastodermal cells (from 95.0±1.3% in the control group to 60.0±2.8% in the group of eggs after three weeks of storage), which negatively affected hatchability of eggs (r=0.99). The egg hatchability in the group after three weeks of storage was 57.0±3.1%, which is 28.1% less than in the control. Long duration of the egg storage period directly and indirectl(due to the inconsistency of the standard incubation regime with the needs of underdeveloped embryos) influenced the intensity of embryo development, duration of hatching period and hatching energy, which negatively affected the quality of chickens.

Egg Fertility

An investigation was conducted to study the effect of storage period on fertility and hatchability in large, medium and small sized eggs of Chabro breed. The study was conducted at poultry farm of SKN College of Agriculture, Jobner. For the present study, a total of 297 eggs were collected for this study. These eggs were grouped into three egg size categories i.e. Small (38-44 g), medium (45-52 g) and large (53-59 g). To study the impact of incubation period, eggs were stored at 21 ̊C temperature for three different time periods (fresh, 3 day and 6 day). It was observed that egg fertility was increased on 3rd day and decreased on 6th day as compared to 0 day. For small egg class, egg fertility was 95.55, 96.02 and 92.13% respectively, on 0, 3 and 6 day of storage. Similarly, for medium-sized egg class, fertility was 95.17, 95.64 and 90.28% and for large sized egg class, it was 91.11, 92.15 and 87.41% respectively, on 0, 3 and 6 day of storage. Embryonic mortality increased with increase in storage duration. For small egg class, egg mortality was 20.95, 17.56 and 24.87% respectively, on 0, 3 and 6 day of storage. Similarly, for medium-sized eggs class, mortality was 10.15, 8.45 and 12.63% and for large sized egg class, it was 29.30, 20.14 and 33.41% respectively, on 0, 3 and 6 day of storage. The egg fertility and mortality are affected by the storage period. For best hatchability, egg storage should not exceed 3 days.

Three Phases

Main goal of this research was to determine the influence of Cobb 500 hybrid broiler parent age (BPA) and egg storage (ES) period, the impact of egg maturity on egg fertilization and chick hatching, as well as on embryonal mortality of chicks during incubation period. There were three phases of production cycle, three different ages of broiler parents 25, 41 and 58 weeks (BPA25, BPA41, BPA 58). The eggs there were differentiated according to storage time: eggs stored up to 7 days and eggs stored over 7 days (ES<7; ES>7). Using the random sample method, 1.050 eggs were chosen (total number of chosen eggs was 6.300), with the aim to determine above mentioned reproductive parameters, one day old chick weight and relative share of chick weight in total egg weight were determined. Age of broiler parents had the highest influence on egg fertility as the highest number of fertilized eggs was recorded during the middle of production cycle (BPA41 = 97.05%), then at the beginning of the cycle (BPA25 = 96.09%), and lowest number of fertilized eggs was during the last phase of the cycle (BPA58 = 93.00%). The storage period of the eggs did not have any influence on egg fertility. However, the age of broiler parents and storage period had significant influence on hatching, therefore it influenced embryonal mortality during incubation period. Without considering the storage period, the lowest embryo mortality was detected with eggs that originated from BPA41 - 13.05%, eggs that originated from BPA58 had significantly higher embryo mortality rate 15.87%, and the highest mortality rate was noted with eggs that originated from BPA25 16.93%. However, extended storage period for the eggs or egg maturity (ES<7 and ES>7) had influence on total embryonal mortality rate in all three phases of the production cycle. Moreover, broiler parent age had statistically significant influence on increase of egg weight (P<0.001) and hatched chick weight (P<0.001), while the relative share of chick weight in total egg weight was decreased, therefore storage period in all three phases of production cycle had negative influence on chick percent, with increase of storage time of the egg, relative share of chick weight in total egg weight decreased, especially during start BPA25 and end BPA58 phase of the production cycle (P<0.001).
