Animal welfare is one of the core concerns in the field of animal science, with behavior serving as a direct reflection of emotional state and health, and thus a key indicator for welfare assessment. With the widespread adoption of intensive farming systems, abnormal behaviors in pigs have become a prominent marker of compromised welfare. In the past few years, the role of gut microbes in the regulation of animal behavior has received increasing attention. This review summarizes the strong relationship between pig behavior and welfare, and focuses on the emerging research linking gut microbiota to behavioral expression in pigs. Furthermore, it outlines the mechanisms by which the microbiota modulates behavior through the microbiota-gut-brain axis (MGBA), including immune, endocrine, and neural pathways. Additionally, the potential of microbiota-targeted interventions to improve pig welfare, including probiotics and prebiotics, will be evaluated. As a critical bridge connecting physiology and psychology, the gut microbiota shows significant promise for advancing welfare regulation in pigs.
动物福利是动物科学领域的核心关注点之一，行为作为情绪状态和健康的直接反映，因此是福利评估的关键指标。随着集约化养殖系统的广泛采用，猪的异常行为已成为福利受损的突出标志。在过去几年中，肠道微生物在调节动物行为方面的作用受到越来越多的关注。本综述总结了猪行为与福利之间的紧密关系，并重点关注将肠道微生物群与猪行为表达联系起来的新兴研究。此外，它概述了微生物群通过微生物-肠道-脑轴（MGBA）调节行为的机制，包括免疫、内分泌和神经途径。此外，还将评估针对微生物群的干预措施（包括益生菌和益生元）改善猪福利的潜力。作为连接生理和心理的关键桥梁，肠道微生物群在推进猪的福利调节方面显示出巨大潜力。
