Beef is big in the United States. The US produces more beef, exports more beef, and consumes more beef than any other country in the world. In 2021, US farmers sold $78 billion worth of cattle. This put more dollars into farmers’ pockets than any other farm product. In total, cattle account for 17% of all farm income in the US.

Last year, the US produced 28 billion pounds of beef. We exported 3.4 billion pounds of beef to other countries. In descending order, Japan, South Korea, China, Mexico, and Canada are the biggest import countries. These 5 countries account for 80% of all US beef exports.

Cattle need land. There are 1.89 billion acres of land in the lower 48 states. Eighty three percent of this land is classified as farm or forest land. The breakdown of this productive farm and forest land is 41% range and pasture, 34% forest land, and 25% crop land.

These are all facts and statistics from the United States Department of Agriculture. They answer the “what” question - the things that can be measured and counted. This does not answer the “why” question -  why is beef production so big in the United States?

There are two reasons why beef production is dominant in the United States. First is consumer demand. Americans love hamburgers, steaks, and beef fixed just about any way there is to fix it. All the slogans “Beef, it’s what’s for dinner”, “Where’s the beef?", and “Got beef?” all resonate with Americans.

The second reason beef production is dominant in the US is because of the unique digestive system of cattle. Most people know cows have four stomachs. Or more correctly, they have one stomach with four compartments. Animals that have a digestive system like this are called ruminants. The advantage of having three extra stomach compartments is not so you can eat more Thanksgiving dinner, it’s the ability to digest fiber.

Being able to digest fiber might not seem all that great, but it REALLY is. Being able to digest fiber means you can digest low quality feedstuffs like grass or other high fiber plant material. Farmers use their best land for crop production. The land that is not suited for crop production (because it is steep or unproductive) can be used as pasture (or forest land). Cattle are raised on this marginal land that is less suitable for crop production. Cattle do not occupy land that is valuable for crop production. High value land is used for crop farming (and housing developments).

The United States is the world’s leader of corn production. We produce more corn than any other country. The next four highest producing countries (China, Brazil, India, and Argentina) when added together, equal the US corn production.

Ethanol that is blended with gasoline is used to fuel our cars. Ethanol is made from corn. Last year, one out of every three kernels of corn produced in this country was turned into ethanol for fuel. In 2021, 15 billion gallons of ethanol were produced in the United States. For each gallon of ethanol produced, there are 9 pounds of “byproduct” produced. There is not a lot of demand for the stuff left after ethanol is produced from corn. This byproduct stuff is basically a mixture of protein and fiber.

Ethanol production creates 135 billion pounds of this protein and fiber “byproduct”. There are not a lot of uses for 135 billion pounds of this stuff. However, if you have three extra stomachs, you can turn this mountain of low quality product into a slightly smaller mountain of high quality stuff. That is what happens in the United States. Farmers use cattle to turn 135 billion pounds of very low value byproduct into 28 billion pounds of high quality beef. All this happens because of those three extra magical stomachs.
