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.

Abstract The aim of this study was to determine the effect of egg water loss during storage and incubation on hatch rates in heavy-type broad-breasted white BUT Big 6 turkeys. Turkey hens started laying eggs at 30 weeks of age. In weeks 2, 8, 16 and 21 of the laying season, 1512 eggs were selected randomly and divided into 4 groups of 378 eggs each. The groups of eggs were stored for 7, 10, 13 or 17 days before incubation. At the beginning and end of the storage period and on days 9, 15, 21 and 24 of incubation, eggs were weighed to determine the percent water loss relative to the egg’s weight. Four incubation cycles of 378 eggs each were performed for each storage period. A total of 16 incubation cycles were carried out (4 weeks of the laying season × 4 egg storage periods) and the following parameters were determined (%): egg fertilization, dead embryos, unhatched eggs and hatchability results from fertilized eggs. The percentages of dead embryos and unhatched poults with physical defects and abnormal position were determined in hatchery waste from each incubation cycle. Egg water loss varied throughout storage and reached 0.57% of total egg weight after 7 days, 0.79% after 10 days, 0.87% after 13 days and 1.28% after 17 days (P≤0.05). After 7 days of storage, egg water loss during a 15-day and 21-day incubation period reached 5.76% and 8.72%, and lower values were noted after 17 days of storage (P≤0.05). Egg water loss of 1.28% during storage resulted in a high rate of early embryonic mortality (14.81%) and a low hatch rate (72.12%) (P≤0.05). High water loss in stored eggs contributed to a higher percentage of congested embryos. During storage, egg water loss reached 0.72% in week 2 of the laying season, 0.78% in week 8 and ≥1% in weeks 16 and 21 of the laying season (P≤0.05). Egg water loss during a 21-day incubation period was similar in weeks 2, 8 and 16 of the laying season, and lower in week 21 (P≤0.05). The hatchability of turkey eggs was lowest in weeks 16 and 21 of the laying season (P≤0.05). Low water loss during incubation contributed to a high rate of late embryonic mortality (13.2%). High water loss during egg storage is accompanied by lower water loss during incubation. Water loss should be monitored after storage and on days 15 and 21 of incubation to evaluate water metabolism in hatching eggs.

Abstract The glass-shelled egg has various points on the surface with light gray coloration, which becomes more visible with the passage of egg storage period. The objective of this work was to evaluate the stage of embryonic mortality, egg weight during the incubation period, hatch window, and quality of chicks at hatch from glass-shelled egg. The research was divided into two parts. In the first part, 80 eggs from 45 weeks old hens were incubated, being half normal eggs and half glass-shelled eggs, while in the second part, 80 eggs from 70 weeks old hens from the same flock as the previous one were incubated. Again, half were normal shelled and half were glass-shelled eggs. No differences were observed for embryonic mortality, egg weight, hatch quality (hatch weight, uniformity, and navel quality), and hatch window between normal and glass-shelled eggs from hens of 45 and 70 weeks of age. However, there was higher contamination in glass-shelled egg from 70-week-old breeder hens. The results show that the presence of glass-shelled egg does not seem to interfere with the quality of the chick at hatch in the breed, ages, and studied conditions, but causes higher contamination in glass-shelled egg from 70-week-old breeder hens.

A total of 9360 eggs was used in two series of experiments to study the effect of pre-incubation treatments on hatchability, egg weight, and chick weight. These treatments involved plastic packaging, alterations in atmospheric carbon dioxide, temperature, humidity, and time during the pre-incubation stage.Hatchability was maintained at a higher level when eggs were enclosed in plastic film during the pre-incubation period. There was also evidence that plastic packaging was more beneficial when eggs were held at adverse temperatures. Temperatures from 50 to 66° F did not appear to have a detrimental effect on hatchability when eggs were held for short storage periods. An increase in the carbon dioxide concentration in the egg storage environment depressed hatchability.Long pre-incubation holding periods tended to decrease egg weight at setting time and at the 18th day of incubation but appeared to increase chick weight. Temperatures ranging from 50 to 64° F had little effect on egg and chick weights. High humidity levels increased egg weight (when eggs were not enclosed in plastic packages) but this weight difference disappeared during incubation.

Abstract. This study was undertaken to determine the effects of storage period and egg weight of hatching eggs of Japanese quails on fertility, hatchability results. Eggs were obtained 150 females quails, all at 15 weeks of age. A total of 1942 hatching eggs were separated into 3 groups as light-weight (9.50-10.50 g), medium-weight (10.51-11.50 g), and heavy-weight (11.51-12.50 g). Based on storage period, eggs were divided into 5 groups as group 1 (0-3 days), group 2 (4-6 days), group 3 (7-9 days), group 4 (10-12 days), and group 5 (13-15 days). The influence of storage period on hatchability of fertile eggs and early, middle, and late period embryonic mortality rates was found significant (P<0.01). The effect of egg weight on fertility rate, hatchability of fertile eggs and early embryonic mortality was significant (P<0.05, P<0.01). The significant differences between storage period groups were observed in hatchability of fertile eggs. The differences between egg weight groups for fertility rate, hatchability of fertile eggs and early embryonic mortality was significantly higher in light weight group than the other egg weight groups. Results of this study concluded that a 12 day pre-incubation storage of hatching eggs of Japanese quails did not appreciably affect hatching parameters. Use of medium or heavy weight eggs for hatching may reduce early embryonic mortality rate.

Weight Groups

A study was conducted to determine the effects of pre-incubation egg parameters on post-incubation parameters in Uttara breeder hens. A total of 2,890 hatching eggs were classified according to three egg weight groups viz. small (44-52 g); medium (53-57 g) and large (58-68 g). Results indicated that large-sized eggs produced chicks with higher hatch-weight than medium and small-sized eggs. However, no differences were observed for fertility and hatchability rates but significant differences were found for chick quality and chick weight. It was therefore concluded from the results of the present study that sorting of eggs by weight prior to incubation might be advantageous in producing uniform size hatchlings to meet specific market demands with focus on breeding for obtaining maximum number of saleable chicks.

And Storage

The influence of breed and storage period of hatching eggs on the duration and results of incubation and the development of quail was studied. It has been noted that in breeding quail farms, the collection period for hatching eggs can be as long as 2-3 weeks. Storage time has a negative effect on incubation time, embryo development, egg hatchability and hatchability of young chicks, which consequently reduces the economic efficiency of the poultry farm. The study was carried out on the eggs of the Pharaoh and Texas White quail breeds. It was found that storage of quail eggs for more than 7 days reduces the hatchability of eggs by 8.3-38.2% and the hatchability of young quail eggs by 15.7-41.4%. Reduced fertilization of eggs correlated with the loss of egg weight during storage (r = 0.974-0.995, p < 0.05). Extending the shelf life of quail eggs to 14-21 days increased the average incubation hour of the Pharaoh breed by 6.3-12.1 hours, and the Texas white breed by 2.5-9.7 hours, had a significant effect during the embryogenesis period on the live weight of day-old quails of both breeds, utilization of yolk sac nutrients and development of the heart, liver and gizzard (η2 = 0.541-0.902, p <0.05-0.01). Hatchery eggs of the meat quail breeds Pharaoh and Texan White should be stored for no more than 7 days before incubation. The results of this study can be used in breeding, industrial and farm quail farms for planning sampling times, the number of eggs laid for incubation and places for planting day-old chicks, the number of future layers, the amount of feed needed; in the educational process of agrarian educational institutions.

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.

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).
