The microbiota gut brain axis as a new biological pathway modulated by human-pig interactions

The microbiota-gut-brain axis is crucial in modulating pig stress response, behaviour, and overall welfare. Previous research has highlighted that stressful management practices can lead to gut microbiota (GM) dysbiosis, adversely affecting pig health and welfare. This study aimed to explore the impact of the quality of human-animal relationships on the GM composition of pigs, given the established bi-directional link between stress and GM composition.Positive handling practices enhance gut health, promoting a more diverse and potentially resilient GM. This study emphasizes the intricate relationship between management practices and gut microbiota, suggesting that positive interactions with pigs could be pivotal in enhancing pigs' microbial health and overall welfare.
