Stop ethanol and the attached subsidies, too.
It isn’t that easy.
The corn is digest to make ethanol, and the distillers grains are then fed to the cattle. Cattle like that better than raw corn (the high carb load isn’t something cattle were made to eat).
Short term, ethanol doesn’t impact the cattle market one way or another. However if the DDG market dries up the feed costs will increase as a result of having to change the ration.
Forgot to add that the ethanol market should be focusing on servicing the feed market. Not the way it is now.
To much boondoggle money makes for bad business plans.
