A core microbiota dominates a rich microbial diversity in the bovine udder and may indicate presence of dysbiosis

Abstract The importance of the microbiome for bovine udder health is not well explored and most of the knowledge originates from research on mastitis. Better understanding of the microbial diversity inside the healthy udder of lactating cows might help to reduce mastitis, use of antibiotics and impr...

Better understanding of the microbial diversity inside the healthy udder of lactating cows might help to reduce mastitis, use of antibiotics and improve animal welfare.

The overall composition of the udder microbiota was highly diverse and significantly different between cows and between quarter milk samples from the same cow.
