“…Las aves de granja son criados con dos propósitos, producción de huevos o producción de carne, donde existe una preferencia de sexos (Bayer et al, 2023); en la producción de pollos de engorde se prefieren machos debido a su mayor precocidad y mejores parámetros productivos que las hembras (Steiner et al, 2011), por el contario en las gallinas de postura comercial se prefieren a las hembras debido a los machos no son viables para producción de huevos ni para carne (Alin et al, 2019;Preuße et al, 2023). Los pollitos que nacen con el sexo no deseado son sacrificados dentro de las 72 horas posteriores a su nacimiento mediante trituración o exposición al gas (Aleynikov & Osipenko, 2023;Kaleta & Redmann, 2008), y son utilizados con otros fines, por ejemplo, como alimento de otras especies (Göhler et al, 2017;Gremmen et al, 2018). Se estima que anualmente a nivel mundial se sacrifican aproximadamente siete mil millones de pollitos machos recién nacidos, especialmente en el sector de producción de huevo comercial (Alin et al, 2019;Krautwald-Junghanns et al, 2018;Rutt & Jakobsen, 2022).…”

Poultry farming worldwide presents great development; however, one of the great limitations is the determination of the sex of the embryo in ovo, because on farms birds are raised for two purposes, egg production or meat production, so there is a sex preference. In the commercial egg production line, females are preferred, and newborn males are discarded, millions of chicks being sacrificed worldwide, generating great economic losses; it also represents a serious ethical and animal welfare problem, which is why countries like France and Germany have decreed new regulations that regulate and prohibit the slaughter of male chicks. Multiple optical and non-optical techniques have been proposed for in ovo sexing, but they have not yet been developed at an industrial and commercial level. Of all the available techniques, hyperspectral HSI imaging is shown to be a viable non-invasive and non-destructive technique for in ovo sexing, because it provides extensive spectral information about an egg. In this context, the advances, and approaches of HSI with respect to its potential use in in ovo sexing are discussed. HSIs have demonstrated considerable precision in sexing, however, they present limitations such as complexity in data processing and embryonic development time.

The requirements to the methods of embryo sex determination in an egg have been formulated and substantiated in accordance with the tightening of the previously accepted norms of cockerel culling during incubation. New methods under development for identifying and culling of egg embryos within 7 days of incubation have been analyzed, and their advantages and disadvantages have been described. Two non-invasive techniques have been identified that have some potential for commercialization in the poultry industry (infrared spectroscopy and computer vision). The purpose of the study is to determine the possibilities of a non-invasive method for determining the sex of an embryo in an egg prior to incubation based on intelligent analysis of the proposed morphometric features of poultry eggs. The scientific novelty of the research lies in the fact that for the first time a method of determining sexual dimorphism based on the analysis of egg asymmetry parameters by three spatial coordinates determined by computer vision methods with the use of machine learning has been developed. An experimental unit for viability assessment and establishment of the necessary conditions for incubation and hatching of chicks has been developed to validate the implementation of the proposed method. It includes a smart incubator "Smart Nest", a brooder, a thermal imaging micro-camera TE-Q1, an oil-filled radiator POLARIS model PRE T 0915, an air humidifier Ergopower ER 604, a bactericidal air irradiator-recirculator DEFENDER 2-15C, a thermohygrometer RGK TH-30 and a laptop. For image acquisition, the setup utilized a Canon EOS 2000D EF-S 18-55 III Kit digital camera with a state-of-the-art CMOS sensor (22.3 × 14.9 mm) and a powerful processor. The geometric spatial digital model of each egg was artificially divided into a set of elements by software, by which the asymmetry of the egg shape was determined. In doing so, their shape indices, area, volume and perimeter were determined from the measured linear dimensions of each element. Incubation of 72 fertilized eggs of Dekalb White cross hen was carried out. Following the incubation, it was possible to reliably determine the sex of 38 chicks. Applying machine learning methods in solving binary classification problems for a small sample (38) with high dimensionality of the initial feature set yielded three final models with accuracy metrics AUC = 73–72% and F1 = 69–72%: Random Forest classifier with 4 evaluators and maximum depth of 3; Random Forest classifier with 10 evaluators and maximum depth of 5 and AdaBoost classifier with 4 decision tree evaluators and maximum depth of 3. Experimental confirmation of the relationship between the egg shape asymmetry and its sexual dimorphism will make it possible to approach the solution of the world scientific problem of reliable determination of the egg sex before incubation.
