You mean, microorganisms allow better deconstruction of cellulose which then frees the protein and makes it digestable?

Yeah, ruminants are amazing with their cyclic puking and eating :)

Cows actually can't digest cellulose at all - what they can do is harbour the microorganisms that can. These microorganisms are then eaten by the cow and provide most of the protein in a cows diet.
