“…Strong evidence exists that diet is the major environmental factor contributing to gut microbial variation in horses 11,13,[19][20][21][22][23][24] . Furthermore, the abundance of different species has been reported to vary dramatically based on host-specific factors like co-colonization with enteric parasites 14,25 , pathobionts 7,[26][27][28][29] and host genetics 30 .…”

We simultaneously measured the fecal microbiota and multiple environmental and host-related variables in a cohort of 185 healthy horses reared in similar conditions during a period of eight months. The pattern of rare bacteria varied from host to host and was largely different between two time points. Among a suite of variables examined, equitation factors were highly associated with the gut microbiota variability, evoking a relationship between gut microbiota and high levels of physical and mental stressors. Behavioral indicators that pointed toward a compromised welfare state (e.g. stereotypies, hypervigilance and aggressiveness) were also associated with the gut microbiota, reinforcing the notion for the existence of the microbiota-gut-brain axis. These observations were consistent with the microbiability of behaviour traits (> 15%), illustrating the importance of gut microbial composition to animal behaviour. As more elite athletes suffer from stress, targeting the microbiota offers a new opportunity to investigate the bidirectional interactions within the brain gut microbiota axis.

“…As we have indicated, managing stressful situations for farm and domestic animals is an important objective with many potential benefits. It remains to be seen if this can be achieved by targeting the gut microbiome or if the findings from a recent study illustrating that dietary-induced changes in the hindgut microbiota of horses influenced behavior will generalize to other farm or domestic animals [113].…”

“…Einen großen Einfluss auf die Zusammensetzung der intestinalen Mikrobiota und das Milieu im Dickdarm hat die Fütterung. So führt beispielsweise eine stärkereiche Fütterung zu einem Anstieg von Bakterien, die Stärke verwerten und Laktat produzieren [15] [25] [31] [40], während die Anzahl der für die Faserverdauung zuständigen zellulolytischen Bakterien sinkt [15] [31] [40] [43] [45]. Dadurch kommt es zu einem Anstieg der Laktatund SCFA-Konzentration sowie zum Abfall des pH-Werts im Dickdarmchymus [25] [32].…”

ZusammenfassungDie Mikrobiota im Dickdarm des Pferdes ist ein komplexes Gefüge, das durch die Fütterung stark beeinflusst werden kann. So führt beispielsweise die Fütterung eines stärkereichen Kraftfutters zum Anstieg von Bakterien, die Stärke fermentieren und Laktat produzieren, während sich die Anzahl der für die Faserverdauung zuständigen zellulolytischen Bakterien reduziert. Zur Optimierung der bakteriellen Mikrobiota werden vielfach Probiotika eingesetzt, um beispielsweise den potenziell negativen Einfluss stärkereicher Rationen zu minimieren. Für das Pferd sind in der Europäischen Union zurzeit lediglich verschiedene Stämme der Hefe Saccharomyces cerevisiae (SC) als Probiotikum zugelassen. In-vivo-Studien bei adulten Pferden konnten jedoch keine eindeutigen Effekte einer SC-Supplementation nachweisen.
