Characterization of bacterial microbiota compositions along the intestinal tract in pigs and their interactions and functions

Abstract In addition to its value in meat production, the pig is an interesting animal model for human digestive tract studies due to its physiological similarities. The aim of this study was to describe the microbiome composition, distribution and interaction along the Iberian pig intestinal tract...
