Horses constantly face several challenges inherent to the domestic environment, and it is common for the expression of their natural behavior to be drastically limited. Environmental enrichment has been suggested as an alternative to improve the captive situation of domestic horses. Among the recently proposed enrichment strategies, olfactory stimulation has emerged as a method for improving several aspects related to animal behavior. Olfaction is a sensory modality that plays a significant role in the expression of equine behavior, and in recent years, studies have shown that olfactory stimulation can influence the physiological and behavioral parameters of horses. This review provides current information on the anatomical particularities of the equine olfactory system, presents the physiological mechanisms involved in the odor detection process, and demonstrates how stress can interfere with this process. Finally, the use of olfactory stimulation as an environmental enrichment for domestic horses () is explored. The need for new studies that answer pertinent questions related to this topic is discussed throughout the manuscript.
马匹不断面临着家庭环境中固有的若干挑战，其自然行为的表现大幅受限是很常见的。环境富集已被提议作为改善家养马匹圈养状况的一种替代方法。在最近提出的富集策略中，嗅觉刺激已成为一种改善与动物行为相关多个方面的方法。嗅觉是一种感觉方式，在马的行为表现中起着重要作用，近年来，研究表明嗅觉刺激可影响马的生理和行为参数。本综述提供了有关马嗅觉系统解剖学特殊性的当前信息，介绍了气味检测过程中涉及的生理机制，并展示了压力如何干扰这一过程。最后，探讨了将嗅觉刺激用作家养马匹环境富集（）的方法。在整个手稿中讨论了开展新研究以回答与该主题相关的相关问题的必要性。
