In this study, next-generation sequencing was used to assess changes in the bacterial communities in four locations within calves at four developmental stages. The analysis revealed several taxa coexisted in the rumen, jejunum, cecum, and colon — but that their abundances differed considerably by gastrointestinal tracts, region, and age. These data support a model whereby early and successive colonization by bacteria occurs across the gastrointestinal tract of calves. It also provides insights into the temporal dynamics of the gastrointestinal microbiotaGlossaryView allMicrobiota
