What would happen if our intestine harbours microbial flora exactly similar to that found in the rumen of cattle?

Explanation

It our intestine harbors microbial flora exactly similar to that found in the rumen to cattle, we would be able to digest the cellulose present in our foods because the microbes present in the rumen (a part of stomach) of cattle, collectively called methanogens, are capable of digesting cellulose as they have cellulase enzyme.
