Pork industry has been that way for 20 years. Nothing new. Iowa hogs are owned by Smithfield, Tyson, ISF, or Pipestone. It's actually a great thing for producers. Nowadays in Iowa all you need to do is get a loan for a building backed by your parents or in-laws' farm ground (the very land your first building will sit on is enough), pay it off easily in 2 years, and then the bank will give you an open line of credit for as many as the county will let you build.
Hogs are all owned by the big 4, you get them after vaccination and it's on autopilot from then on. Tyson, Smithfield, and next year Pipestone will even negotiate and contract your feed and trucks for you. It's almost zero risk and nothing but a money maker. And corporate hog farming hasn't driven prices up whatsoever, it's driven them down. What's driving pork prices up is feed, fuel, and DNR compliance. My employer has a side division managing (not owning) 31 buildings in O'Brien, Sioux, Plymouth, and Clay counties. financials all come across my desk. It's never been a better time to be a hog farmer than it is right now, from a small guy with one building all the way up to Iowa Select.
Flat tillable acres in the 16 most NW Iowa counties are at $16K plus right now, in O'Brien/Sioux/Lyon you're not going to get a half section for less than $19K.
