None. If you get enough energy content with feeding oats (especially processed oats), corn is not necessary. However, it depends on the class and breed of beef cattle you are referring to, as well as environmental factors, additional feedstuffs given and accessibility. As such, a person could include anywhere from one percent to as much as 80 percent corn used with oats to feed beef cattle.
No beef cattle can also be fed, grass, corn, insilage, silage, grain, oats, barley.
There are many components that make up feed fro beef cattle, it really depends on where they are located, and the needs of the herd. Normally they are fed any feeds from the following list; corn, COB (corn, oats, barley mixture), insilage (corn cut from the field including stalks). Grains bought from feed stores may include molasses (for flavor) and added vitamins and minerals.
It depends on the location, and the type or class of animals fed. There can be as little as no corn (0%) in a feed ration for cattle, or as much as 85% in a feed ration. Not all areas in the world can or will grow corn, and not all feed fed to cattle includes corn. For instance, much of the grain fed to cattle in Canada is barley or oats, not corn.
Corn (maize) that is fed to livestock such as cattle or hogs.
Organic Beef
No. There are many cattle feeds that are vegetarian besides grass. The most common are corn and soy.

Agriculture includes livestock production. Animal protein is "arguably" a part of normal human nutrition. People make money feeding cattle on pasture or growing corn or silage to feed cattle.
So they could feed the east
That all depends on the cost of each and what type of beef cattle you are feeding: dry bred cows, finishers, growers, lactating cows, or bulls. Shell corn would have a lower energy and protein content than corn gluten, so the shell corn may be best to feed to replacement heifers and growers, and probably even bulls if they don't have much weight to gain, and the corn gluten could be fed to lactating cows or finishers. Dry-bred cows don't need to be grained unless they're too thin and need to have their weight increased prior to calving.
Cattle average from 5.5 to 6.5 lbs of feed per lb of gain. These numbers can vary a lot depending on weight of cattle entering the feedyard, genetic background etc...
