President Lincoln signed the Homestead Act, providing 160 acres of free land to settlers willing to farm it for five years. This legislation dramatically expanded livestock production westward, allowing families to establish cattle ranches and farms across the Great Plains. The act was instrumental in shaping the American livestock industry by making land accessible to ordinary citizens.

Following the Civil War, cowboys drove millions of cattle from Texas ranches to railroad towns in Kansas. These legendary cattle drives, including the famous Chisholm Trail, connected southern cattle ranches to northern markets. This period established the iconic American cowboy culture and created the first large-scale cattle transportation system.

The completion of the transcontinental railroad revolutionized livestock transportation. Cattle no longer needed to be driven hundreds of miles on foot; they could be shipped by rail to markets across the country. This innovation dramatically reduced transportation costs and time, making livestock production more profitable and efficient.

1906: The Jungle Published & Meat Inspection Act

# data[].attributes.body
Upton Sinclair's novel 'The Jungle' exposed horrific conditions in meatpacking plants, shocking the American public. In response, Congress passed the Meat Inspection Act and Pure Food and Drug Act, establishing federal oversight of meat processing. This marked the beginning of food safety regulations that continue to protect consumers today.

As part of the New Deal, the Agricultural Adjustment Act provided government support to farmers, including livestock producers. The act established price supports and production controls to help farmers recover from the Great Depression. This legislation created the foundation for modern agricultural policy and farm subsidies.

1960s: Concentrated Animal Feeding Operations (CAFOs)

# data[].attributes.body
The development of large-scale confined feeding operations revolutionized livestock production. CAFOs allowed producers to raise thousands of animals in controlled environments, dramatically increasing efficiency and reducing costs. This shift from traditional farming to industrial agriculture changed how Americans produce meat, eggs, and dairy products.
