There is an experiment in cows in which they swapped the cow's rumen contents, which is a big gut with way more microorganisms than the regular gut, and their microbiomes reverted back to their original profiles, which is different to these findings in mice here.
I remember hearing about that rumen swap experiment. One of my professors at the time said that more substantial changes could be affected by doing repeat rumen content swaps.
