“…To detect a direct embryotoxic influence of pre-incubation disinfection protocols on day 1, empty eggs detected via candling would have had to be opened up, which was not feasible in routine hatchery processes. Other studies have remarked on the method's susceptibility to errors [43], since infertile eggs and early cleavage stages cannot always be differentiated correctly. However, after extensive examinations, formaldehyde fumigation has not been associated with embryonic mortality [4], and was therefore chosen as the reference method.…”

Objective The use of low-energy electron irradiation for hatching egg disinfection was compared to formaldehyde fumigation. Material and methods To assess the efficacy, eggshells were examined for bacteria before and after disinfection. During incubation, hatching and fattening of 1400 Ross 308 broilers per group candling data, hatching rate, mortality rate and body mass development were recorded to evaluate the impact on health and performance. Additionally, data from the slaughter house and histological evaluation of organ samples were included in the health screening. Results Regarding the efficacy, irradiation and formaldehyde significantly reduced the number of bacteria compared to non-disinfected eggs. However, no significant difference was recorded between both treatments. The irradiated group performed better than the reference group concerning the number of infertile eggs, early and late dead embryos and fertile eggs. The performance during fattening was nearly identical in both groups, while mortality differed slightly between the irradiated group and the group treated with formaldehyde. Upon slaughter, there were minor variations concerning the distribution of findings between the groups, but the number of anomalies was not higher than reference values suggest. Conclusion In both groups no health problems were observed during rearing and the fattening performance met the targets of the manufacturer Aviagen for the used broiler line Ross 308. Clinical relevance Lower-energy electron irradiation proves to be an efficient and well-tolerated hatching egg disinfection procedure. Further field trials are necessary to establish low-energy electron irradiation as an alternative to formaldehyde fumigation.

“…According to Hashemzadeh et al [8], Candling process is labor consuming, and is not very efficient in checking thousands of eggs per day, therefore, the development of an accurate, rapid and cheap machine vision system for detecting the infertile eggs inappropriate time would be advantageous to the incubation industry.…”

The main objectives of the research were to develop a module that classify fertilized/unfertilized duck eggs according to its classification using Light Dependent Resistor during candling process of the duck eggs, a project that segregate the duck eggs to its designated classification area using servo motor, to develop a webpage that displays the number of classified duck eggs in a tabular and graphical presentation using Windows Form and to capture the level of effectiveness of the Automated Duck Egg Classifier with Web-Based Monitoring System in terms of functionality, reliability, usability, efficiency, maintainability and portability. Recipient-beneficiary of the project is the balut producer's industry. The method that was used by the project-developers was waterfall approach as a process model for the system. The project-developers used Visual Studio 2012 as front-end and Text File as back end of the system. Asp.Net will be used for designing the user's interface. Using these applications, the project team created a Web-Based Application that displays the number of classified duck eggs which could be presented in a tabular and graphed. Therefore, the study intended to help the balut producer’s industry. Project developers developed an Automated Duck Egg Classifier with Web-Based Monitoring System that able to solve the aforesaid problems of the producers. The common problem encountered by the said industry is the manual process in classifying duck eggs. After the project was tested, the developers concluded that the project finally resolved the traditional problems of classifying duck eggs as the balut expert stated.

“…To develop a nondestructive detection technique capable of distinguishing fertilized eggs from eggs not suitable for vaccine production, LEDs can be used where visible light and near-infrared (VNIR) spectroscopy techniques are employed in conjunction with a LED light source [ 3 ]. In [ 6 ], the authors used machine vision to identify whether an egg was fertilized. In their study, a LED lamp was used to penetrate the eggshell at a close range, with a CCD camera used to film the embryo growth inside the egg.…”

The fertilized egg is an indispensable production platform for making egg-based vaccines. This study was divided into two parts. In the first part, image processing was employed to analyze the absorption spectrum of fertilized eggs; the results show that the 580-nm band had the most significant change. In the second part, a 590-nm-wavelength LED was selected as the light source for the developed detection device. Using this device, sample images (in RGB color space) of the eggs were obtained every day during the experiment. After calculating the grayscale value of the red layer, the receiver operating characteristic curve was used to analyze the daily data to obtain the area under the curve. Subsequently, the best daily grayscale value for classifying unfertilized eggs and dead-in-shell eggs was obtained. Finally, an industrial prototype of the device designed and fabricated in this study was operated and verified. The results show that the accuracy for detecting unfertilized eggs was up to 98% on the seventh day, with the sensitivity and Youden’s index being 82% and 0.813, respectively. On the ninth day, both accuracy and sensitivity reached 100%, and Youden’s index reached a value of 1, showing good classification ability. Considering the industrial operating conditions, this method was demonstrated to be commercially applicable because, when used to detect unfertilized eggs and dead-in-shell eggs on the ninth day, it could achieve accuracy and sensitivity of 100% at the speed of five eggs per second.
