Bacterial Community Dynamics across the Gastrointestinal Tracts of Dairy Calves during Preweaning Development
Published on 23/02/2018
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
A microbiota is the whole of the ecosystem (bacteria, yeast, fungi and viruses) living in a specific environment. Intestinal microbiota was previously called “intestinal flora.” of dairy calves during preweaning development.
