Nanotechnology, an emerging and promising technology, has been implicated to revolutionize the poultry industry. The main aspect of nanotechnology was to modify or alter the particle size into nanometers and thereby alter the physical as well as chemical features of the particular molecules. Selenium (Se), an essential trace element, can play an immense role in the maintenance of diverse physiological functions, body metabolism and cellular homeostasis, and the performance of poultry. Selenium nanoparticles (Se-NPs) are of growing importance due to its nutrients digestibility, medicinal therapy, targeted drug delivery system, and production of vaccines. Se-nanoparticles are having importance due to its high bioavailability and digestive efficiency. Se-NPs have been implicated to increase relative weights of immune-related organs (burse and thymus) to enhance immunity and thereby modulate egg production as well as the reproductive performance of birds. The present review is highlighted on the significant role of nano-selenium on reproductive performance and immunocompetence in poultry as comparative advantages over conventional sources of Se in poultry diets.
纳米技术是一项新兴的有前途的技术，被认为将彻底改变家禽养殖业。纳米技术的主要方面是将颗粒大小改性或改小至纳米级，从而改变特定分子的物理和化学特性。硒（Se）是一种必需的微量元素，在维持多种生理功能、身体新陈代谢和细胞内环境平衡以及家禽生产性能方面发挥着巨大作用。由于其营养物质的消化率、医学治疗、靶向药物输送系统和疫苗生产，纳米硒（Se-NPs）越来越受到重视。由于其高生物利用度和消化效率，Se-NPs 具有重要意义。Se-NPs 被认为可以增加与免疫相关的器官（法氏囊和胸腺）的相对重量，以增强免疫力，从而调节产蛋量以及鸟类的繁殖性能。本综述重点介绍了纳米硒在家禽繁殖性能和免疫能力方面的重要作用，与家禽饲料中传统硒源相比具有明显优势。
