But these often aren't true.

The cows are raised very differently in each region and by different farmers, but they're often raised by a breeder until they're about 10 months old and then sold at auction to a fattening farmer.

By the time the calves are sold at auction, they can already fetch 40 times the price of us cattle.

The fattening farmer will keep the animals in small pens and feed them a mixture of fiber and high energy concentrate made from rice, wheat and hay.

They're often fed this three times a day for almost two years until the animals are almost 50% fat.

If and when a cow goes to auction, it can sell for as much as $30,000.
