Comparing the amount of domestic animals and wild animals?

Question

From some material, I read about the ammonia (NH₃) emission from animal waste. I found that the emission from domestic animals are greater than wild animals. Then, I can't help wondering the amount of wild animals and domestic animals(cow, pig, chicken, etc). Which has the greater amount on Earth? And how to estimate the amount approximately?

Answer 1

For birds, it's 70:30 domestic:wild by individuals.

For mammals, it's 36% humans, 60% livestock, 4% wild (by numbers).

Per Wikipedia, wet masses run as follows, in millions tonnes

Humans 385

Cattle 520

Other domestic animals 153

Ants 30-300

Termites 445

Earthworms 3800-7600
