In the short run yes. And I would say very competitive long run.

Not that bad really. It develops deep roots very fast. Thats why prairie
plantings are such a pain in the butt for two to three years, they are
building roots first, the top looks little and needs mowing.

Dry prairie really isn't all that productive compared to deep soil mesic
prairie. It's really a soil/water thing. Often the same species occur in
both, just at far different levels of productivity.

More to recharge the aquifers. 5 years to good soil balance, 10 to near
peak production, 10+ to build resilience and develop long term assets like

If you want to look at an angle for Hispanics try selling fresh
meat. Cattle are simply a whole lot easier to work with than most exotic
animals, and more expensive to get into due to high cost breeding
stock. Other issues include game laws, and as we are finding out in WI
prion diseases from imported deer (like mad cow disease).

I'm not trying.

I believe they study many types of livestock.
