Subsidies go mostly to corn and soybeans. Think those are multipurpose but corn is used to feed livestock, of course. 10 or 15% may be a lot in a low-margin industry, and I don't know how it's split among crops.
No all subsidies are direct. For example, water costs too little in Arizona so foreign companies grow feed stock there to ship home.
