Beef Cow-Calf production in the U.S. - The USDA Economic Research Service (ERS) has released a report which states " beef cow-calf production in the United States occurs in every state with about 35% of the 2.2 million farms having a beef cow inventory, in 2007. Most of these were small, part-time operations with about a third of farms that raise beef animal having a beef cow inventory of less than 10 cows, mor than half had fewer than 20 cows, and nearly 80% had fewer than 50 cows.
Many small operations are 'rural residence farms' that specialize in beef cow-calf production with their income from off-farm sources exeeds that from the farm.
Beef cattle production is considered by consumers to be the 2nd largest "factory farming" species/industry. Doesn't sound like there are many of those types of farms and ranches out there.
