(For comparison, there were only an estimated 30 million bison in North America before white settlers began hunting them. The modern cow population dwarfs the historic population of bovines, even when you combine various species on all continents).
This doesn't change the facts that I stated. Herbivores have SUNK carbon into the soil, by grazing and moving on; pushed on by carnivores. Their digestion has no effect on the carbon in the atmosphere.
