The theory of biomass says that the ratio of plant mass to cow mass should be pretty much the same no matter where you are.

But the difference is whether the cow is actually allowed onto the land to access that biomass itself, or whether somebody harvests the crop and processes it into cow food. Which typically also involves lost of chemicals to improve biomass produced per hectare of land.
The issue is the methane which the cows generate in the digestion process and emit. Methane is a much more powerful greenhouse gas than CO2. So one should talk about CO2 equivalents here, not CO2.
