Tractors, swathers, balers, and combines did more work with fewer people. Introduced grass species increased the quantity and quality of feed. Cattle diseases such as blackleg [an acute infection] and brucellosis [causing spontaneous abortion] were identified and controlled through vaccination programs. Scientifically calculated feed rations promoted fast growth. Controlled breeding created animals with desirable genetic traits including rapid growth, better health and ease of calving.

The effect of government on ranching has been profound and changing. Initially Western natural resources seemed limitless. By the late 1800s, overgrazing, excessive timber cutting and environmentally destructive mining and smelting took a toll. Land management agencies were established. The Taylor Grazing Act of 1934 removed public lands from uncontrolled use and made them available through leasing. Ranchers today still depend on these grazing allotments for summer pasture.

Government's role in ranching increased dramatically through the 20th, and into the 21st century. Federally supported programs work with ranchers to promote best management ranching practices for sustainable land and water use. Many of today's success stories relate to a partnership with significant input from the rancher and government agent as stewards of the land.
