The Gut Brain Axis

Our understanding of the significance of the microbiome (organisms of the gastrointestinal tract) has blossomed over the last few decades. The knowledge of the role of gastrointestinal bacteria is growing beyond the nutritional aspects of digestion and production of micronutrients and into rtp slot live its relationship with the brain and behavior. The gut microflora contributions include the development of the immune system, local defense against gastrointestinal pathogens, response to allergens, modulation of inflammation and most recently communication with the central nervous system. This communication is known as gut-brain axis.

The gut-brain axis is being studied in many different mammals.  A recent manuscript (1) associated physical and mental stress to changes in the GI flora in the horse. This work reveals the importance of gut microbial flora to equine behavior.  Behaviors evaluated during times of stress Slot Gacor Anti Rungkad included aggression, withdrawn Link slot gacor postures, cribbing, weaving and head bobbing.  Work in other species has identified a role of GI flora influencing behaviors such as anxiety, depression and an autism-like syndrome (2,3,4,5). Lactobacillus reuteri, a beneficial bacteria found naturally in mammals, has been identified as a component of this research. Our equine probiotic, EquiOtic, contains live, equine sourced lactobacillus reuteri.

Concluding: The gastrointestinal flora is increasing as a non-nutritional consideration in horse health. Lactobacillus reuteri has previously been documented to influence numerous areas of animal health; development of the immune system, gastrointestinal infection, gastric ulceration and the inflammatory response. The gut brain axis is an additional health benefit that can be added to the growing list of Lactobacillus Reuteri health benefits.
