Cows shouldn’t eat to much straight corn. To many starches. Corn that has been digested via ethanol (DDG) or other corn processing makes for a much better feed.
I misspent my youth in the ethanol industry. Enjoyed the challenge, but it was working for the government without the benefits. The best plants were those who were primarily supplying feed to cattle. Rather than just tune for ethanol production, you were shooting to improve the ration for the herd/s. So the goal was to make better feed (and CO2) with the ethanol as a byproduct.
However, at the end of the day, most companies were living off the subsidy. My old firm went bankrupt almost two years ago because they didn’t fill out the grant paper work correctly. Their business was “good”, but they couldn’t survive in ethanol, solar, and wind without those grants.
Similar reason why I suspect Tesla is going to fail. They are dependent on outlawing internal combustion engines.

True. Cows much prefer corn that been “working” in the silo for several months.

For ruminating animals more sugar means more problems.
They all do better on low energy straight grass hays as the place they get the vast majority of their daily calories from.
