The vast majority of animals raised for food in the United States are raised in factory farms, where they are confined to small spaces and treated with antibiotics and hormones to make them grow faster and to produce more milk and eggs. These animals are typically kept in conditions that are cramped, dirty, and stressful, and they are often unable to express natural behaviors.
As a result of these conditions, factory-farmed animals often suffer from physical and psychological problems. For example, chickens may develop breast blisters and hock burns from standing on wire floors, and pigs may become crippled from being confined to gestation crates that are too small for them to turn around in. In addition, these animals are often fed an unnatural diet of grains and other processed foods, which can lead to health problems.
The sad reality is that these animals are often seen as nothing more than commodities, and their welfare is often secondary to profit. As a result, they often suffer in silence, with little hope of ever experiencing a better life.
