If by trails you mean cattle drives, the purpose was to move large herds of cattle to the nearest railroad stop so the cattle could be shipped to other parts of the country, usually larger cities in the east.

Cattle trails were commonly found in the 19th century in the western United States, particularly in states like Texas, Kansas, and Nebraska. These trails were used to drive cattle from ranches to railheads for transportation to markets. Many of these historic cattle trails have since been incorporated into modern roads and highways.
The three great cattle trails include the western trail, the Chisholm trail and the goodnight loving trail.
Chisolm Trail is one.

I don't think it was the cattle trails themselves that changed the industry, it was more or less the building of the railroads, more pioneers taking over the land, and barbed wire that changed the cattle industry as a whole.
because of the increased prices thwy had no food or anything so they might as well have had to move on the cattle trails :0
