Is the issue the availability of grass or simply not enough space to be profitable? Concentrated Animal Feeding Operations, by their definition, are profitable because they jam as many animals as possible into a small space. So, I think this has more to do with the economics and profit margins desired by the conventional producers/investors, not necessarily the supply of grass. I think you’d lose all your economies of scale and efficiencies by trying to turn CAFOs into pastured operations (i.e., no one would do it).
