Abstract: Stress refers to the non-specific responses of a stimulated body to different stressors and the subsequent maintenance or restoration of internal environmental homeostasis.Adverse stress reactions lead to general balance disruption and may cause digestive,neurological,and endocrine disorders,and decreased immune capacity,which seriously impact host health.As the core compo-nent of intestinal micro-ecology,the intestinal flora can greatly alter its own composition,distribu-tion,function,metabolic product output,and other aspects during stress,which cause disorders and aggravate homeostatic imbalance in internal environments.While the intestinal flora is of great sig-nificance to animal medicine and agricultural production,little is known about stress and its impact on intestinal flora.Therefore,we briefly reviewed the impact of stress on animal intestinal flora in combination with the latest research and provided theoretical insights on intestinal health research.
