During the Civil War, where did the number of cattle dramatically increase?

The significant increase in cattle numbers during the Civil War occurred in Texas. The state had vast ranching lands and was pivotal in providing beef to both the Confederate and Union armies. The war created a high demand for cattle, leading to a substantial rise in ranching activities. Texas ranchers capitalized on this demand, and as a result, cattle herds multiplied dramatically.

While other regions like New Mexico had some cattle production, Texas truly became the epicenter for cattle raising during that period, driven by its geographical advantages and the economic necessities of the war. This provided a major boost to the local economy and solidified Texas's reputation as a key player in the beef industry. In contrast, the other options do not share the same level of historical significance regarding cattle proliferation during the Civil War.
