The reproductive physiology of canids is unique compared to other mammalian species. Specifically, the reproductive cycle of female canids is characterized by extended periods of proestrus and estrus followed by obligatory diestrus and protracted ovarian inactivity (anestrus). Although canid reproduction follows this general pattern, studies have shown variations in reproductive biology among species and geographic regions. Understanding of these differences is critical to the development of assisted reproductive technologies including estrus induction, gamete rescue, and embryo production techniques for canid conservation efforts. This review summarizes current knowledge of canid reproduction, including estrus cyclicity, seasonality, and seminal traits, with the emphasis on species diversity. The application of reproductive technologies in wild canid conservation will also be discussed.
与其他哺乳动物相比，犬科动物的生殖生理具有独特性。具体而言，雌性犬科动物的生殖周期特点是发情前期和发情期延长，随后是必然的发情后期和长期的卵巢静止期（乏情期）。尽管犬科动物的繁殖遵循这一总体模式，但研究表明，不同物种和地理区域的生殖生物学存在差异。了解这些差异对于开发辅助生殖技术至关重要，这些技术包括用于犬科动物保护工作的发情诱导、配子挽救和胚胎生产技术。本综述总结了犬科动物繁殖的现有知识，包括发情周期、季节性和精液特征，重点是物种多样性。还将讨论生殖技术在野生犬科动物保护中的应用。
