What development led to the raid growth of the cattle industry?

The rapid growth of the cattle industry was primarily driven by the expansion of railroads in the 19th century, which enabled the transportation of cattle from ranches in the West to markets in the East. This transportation revolution facilitated the efficient movement of livestock, leading to increased demand and profitability. Additionally, the rise of beef consumption and the availability of vast grazing lands contributed to the industry's expansion. Together, these developments transformed cattle ranching into a major economic enterprise in the United States.
