Has domesticating livestock influenced micro biome in animals?

Changes in diet and even chemical control with the use of antibiotics has surely had an effect on the gut flora of so many animals no?  

If so has there been new species evolve - possibly like the plastic eating variety mentioned in a recent post - entirely made possible due to the changed biochemistry of the domestication history?

Lastly could some of those have migrated to wild animals, or crossed species ?

I think there's no answer because it's a really good question. Microbiome research in humans really only got popular (funding) in the past 10 years. So if anyone's working on it, it's probably a shady global agriculture corporation or some struggling PhD student who's your soulmate.
