“…our findings align with the results of 33 , As indicated by their research, which involved raising the eggshell temperature to 38.9 °C for the Cobb 500 commercial breeder flocks aged 37 to 45 weeks, starting from E 8 onwards, led to significant percentages of egg weight loss at E18. However, this effect did not extend to create substantial differences in the overall egg weight.…”

“…It is evident that an extended storage duration resulted in a decrease in the body weight of the control group compared to the SPIDES groups. In this context, 33 observed that elevating the eggshell temperature to 38.9 °C for 6 h during the incubation of Cobb 500 commercial breeder flocks aged 37 to 45 weeks, starting from E8 onwards, led to extended chick length after hatching but reduced body weight compared to the control group. In contrast to our findings, 36 demonstrated a significant improvement in chick weight at hatch following thermal conditioning at 40 °C for 4 h per day from E14 to E17, in comparison to the control group.…”

The short periods of incubation during egg storage (SPIDES) method enhances the quality of chicks and improves hatching rates. Additionally, embryonic thermal conditioning (TC) is a technique used to enhance thermotolerance in birds. Previous studies have evaluated the effects of SPIDES and embryonic TC separately. Yet, our hypothesis postulated that a synergistic effect could be achieved by integrating TC and SPIDES, thereby enhancing the broilers' resilience to thermal stress. We conducted an experiment involving 800 Ross broiler eggs, divided into two groups. The first group, referred to as S0, was maintained under standard storage room conditions and acted as our control group. The second group, known as S1, underwent a process called SPIDES for 5 h at a temperature of 37.8 ± 0.1 °C, on three occasions: days 5, 10, and 15 following egg collection. Upon reaching the 14th day of incubation (DOI), each of these primary groups was randomly subdivided into two equal subgroups. The control subgroup, designated as TC0, remained in the usual incubation conditions. Meanwhile, the other subgroup, TC1, was subjected to prenatal heat conditioning at a temperature of 39.5 ± 0.1 °C for 6 h per day, commencing on the 14th embryonic day (E) and extending until the 18th embryonic day (E). This experimental setup resulted in four distinct experimental subgroups: S0TC0, S1TC0, S0TC1, and S1TC1. The findings indicated that the combined application of SPIDES and TC had a significant positive effect on chick performance after hatching. Specifically, the (S1TC1) group exhibited the heaviest live body weight (LBW) and body weight gain (BWG) at the marketing age in comparison to the other groups. Furthermore, both SPIDES and TC had a positive influence on the relative weights of breast muscles and their histological measurements. The (S1TC1) group displayed significantly higher values in terms of the relative weight of breast muscles and the number of myocytes. In conclusion, SPIDES and TC have beneficial effects on pre- and post-hatch characteristics of broiler chicks up until the marketing age. Additionally, TC techniques improve chick performance, particularly under conditions of heat stress, and enhance the yield of breast muscle in later stages of life.

“…In the incubator there are lights that are used to warm the eggs so that the eggs can hatch with good quality even without the mother hen incubating them. Good hatchability is influenced by several factors such as the temperature in the incubator must be stable between 37 ° C -38 ° C, humidity is maintained at 50% -55% and turning eggs must be done 3 times a day, ideally turning eggs every 8 hours on day 4 after the eggs are put into the incubator [5] [6]. But in general, in the process of hatching eggs there are often several obstacles.…”

An egg incubator is a technology in the livestock industry used for automated and efficient egg hatching. However, in its development, existing egg incubators only utilize incandescent lamps without any notification system to indicate when the chicken eggs have hatched, and there is no temperature or humidity detection in the incubator. As a result, the incubator’s situation during the egg hatching process remains uncontrolled. Therefore, this research, we designed and constructed an egg incubator machine that utilizes a microcontroller as the main control unit, responsible for regulating temperature, humidity, and egg rotation. Through the implementation of the Internet of Things, this egg incubator is connected to the internet as a communication tool using specialized software, allowing farmers to remotely monitor the device. Users receive information about the incubator machine through the Telegram mobile application, such as the current temperature and humidity inside the incubation room, up to the hatching status of the eggs. Based on the test results conducted, it can be concluded that the hardware has been successfully developed using the Microcontroller. In the temperature sensor test, there was an average error of 3.14% in temperature readings and error 5.91% in humidity readings. Overall, the device has functioned well and as intended, which includes temperature and humidity readings, controlling the timing of the lamp, and shifting the egg tray. The performance test of the device successfully hatched eggs on time (for 21 days) with a success rate of 90%.

“…Normally, the incubation conditions of oxygen (O 2 ) and carbon dioxide (CO 2 ) are 21% and 0.5%, respectively [5]. Carbon dioxide is an important gas in embryonic development which is released first during incubation from egg albumen as a natural reservoir and as the metabolic by-product of the embryos [6,7]. In addition, Sadler et al [8] found that 4% CO 2 could enhance embryonic growth during the first 48 h of incubation and improve amnion closure during early incubation.…”

Background and Aim: The exchange of oxygen and carbon dioxide (CO2) in the incubator plays a key role in embryonic development and hatching. This study aimed to study the effect of non-ventilated (NV) intervals during the early stage of embryonic development on the hatching process. Materials and Methods: Hatching eggs (n = 7200) were equally divided into four treatment groups and incubated in four incubators. The first group was incubated in normal ventilated condition (V) during the setting phase of incubation. Ventilation holes of the three remaining incubators were closed for the first 3, 6, and 9 days and termed as NV groups (NV1, NV2, and NV3, respectively). A gradual increase in CO2 was allowed for NV groups, followed by opening the incubator holes to permit ventilation throughout the rest of the incubation periods. Results: Obtained results demonstrated that CO2 concentration gradually increased up to 0.19% for the NV1 group, 0.41% for the NV2 group, and 0.90% for the NV3 group, while CO2 concentration remained at 0.08% during the first 9 days of incubation in the V group. Albumen pH was lowered for all NV groups. The highest hatchability percentage was recorded for NV3 followed by NV2 and NV1 groups. All NV groups represented earlier and narrower spread of hatch and higher hatched chick weight. Embryos and hatched chicks in the NV groups had higher hormonal levels of thyroxin and corticosterone. Conclusion: All non-ventilation periods had positive effects on narrowing the spread of hatch, increasing hatched chick weight and hatchability percentage compared to the normal V condition. Furthermore, the non-ventilation throughout the first 9 days of incubation yielded the best hatching results. Keywords: albumen pH, carbon dioxide, embryonic hormones, hatchability, non-ventilation.
