U.S States with the Most Cows

You're a professional cow?

Texas isn't particularly dense outside of the cities, and it's a big state, so I don't see why it wouldn't have cows

Not financially

It's mostly a matter of economics. You are going to use the land available to get the greatest return on investment. Outside of a few exceptions cows give you the most return per acre of grazing animals so if you are using a field for pasturing you are going to prefer raising cattle to sheep, goats, llamas etc. The vast majority of cattle never eat anything other than grasses until they are moved to the finishing lots. If the land supports cattle herds you are going to raise cattle. Go further west than Denver you don't get enough rain to support the grass growth needed for cattle farming and you start seeing hardier grazers until you get to the Pacific bordering states. Once you get to central Iowa you start getting better soil and more rain. This allows for farming that has a lot higher return than herding livestock. The economics of agriculture and the geography/climate of the US explains why there is cattle belt that runs from the Gulf of Mexico to the Dakotas.

The only one that tripped me out.
