Our Commitment

150 Years of Breeding, Raising, and Caring for Horses

In the same era that President Ulysses S. Grant designated Yellowstone as the first National Park and the very first Kentucky Derby was run, the Four Sixes Cowboys rode out from the headquarters on what would one day become some of the greatest utility and sport horses the world would ever know.

Staying relevant to become a legend in the horse business like the Four Sixes Ranch has required adapting and adopting new technology and best practices. Today we manage mares, foals, performance, and solid working horses. Each requires different feed and supplement care based on specific needs.

And we are proud to bring our superior formulations to horse owners everywhere.
