The culling of day-old male chicks has caused ethical and economic concerns. Traditional approaches for detecting the in ovo sex of chicken embryos involve opening the eggshell and inner membrane, which are destructive, time-consuming, and inefficient. Therefore, noncontact optical sensing techniques have been examined for the in ovo sexing of chicken embryos. Compared with traditional methods, optical sensing can increase determination throughput and frequency for the rapid sexing of chicken embryos. This paper presented a comprehensive review of the different optical sensing techniques used for the in ovo sexing of chicken embryos, including visible and near-infrared (Vis-NIR) spectroscopy, hyperspectral imaging, Raman spectroscopy, fluorescence spectroscopy, and machine vision, discussing their advantages and disadvantages. In addition, the latest research regarding different detection algorithms and models for the in ovo sexing of chicken embryos was summarized. Therefore, this paper provides updated information regarding the optical sensing techniques that can be used in the poultry industry and related research.
淘汰一日龄雄性雏鸡引起了伦理和经济方面的关注。传统的鸡胚性别鉴定方法涉及打开蛋壳和内膜，这些方法具有破坏性、耗时且效率低下。因此，人们研究了非接触式光学传感技术来进行鸡胚的性别鉴定。与传统方法相比，光学传感可以提高鸡胚快速性别鉴定的测定通量和频率。本文全面回顾了用于鸡胚性别鉴定的不同光学传感技术，包括可见和近红外（Vis-NIR）光谱、高光谱成像、拉曼光谱、荧光光谱和机器视觉，讨论了它们的优缺点。此外，还总结了鸡胚性别鉴定的不同检测算法和模型的最新研究。因此，本文提供了有关可用于家禽业和相关研究的光学传感技术的最新信息。
