Pig Gut Health and Welfare: Microbiome Research

Research into the pig gut microbiome is revealing connections between intestinal health, systemic welfare, and sustainable production approaches.

Key Facts

The pig gut contains approximately 500-1000 bacterial species in a healthy microbiome
Post-weaning dysbiosis is a leading cause of diarrhoea and poor welfare in young pigs
Antibiotic reduction creates pressure to find microbiome-supportive alternatives
Probiotics, prebiotics, and organic acids show promise in maintaining gut health without antibiotics

Welfare Considerations

Gut health is foundational to pig welfare, affecting nutrient absorption, immune function, and behaviour. Research into microbiome management represents a promising pathway to improve welfare while reducing antibiotic dependence.
