Industrial Agriculture: The Reality of Feed at Animal Factories

When many Americans think of farm animals, they picture cattle munching grass on rolling pastures, chickens pecking on the ground outside of picturesque red barns, and pigs gobbling down food at the trough.

Many people are surprised to find that most of the food animals in the United States are no longer raised on farms at all. Instead they come from crowded animal factories, also known as large confined animal feeding operations (CAFOs).
Just like other factories, animal factories are constantly searching for ways to shave their costs. To save money, they've redefined what constitutes animal feed, with little consideration of what is best for the animals or for human health.
