Kellogg had a longtime interest in Arabian horses, and purchased 377 acres (1.5 km2) for $250,000 in Pomona, California, to establish a ranch.

After erecting the first buildings, Kellogg funded the development of an Arabian horse breeding program, which (as of 2008) remains the oldest in the United States and the fifth largest in the country.

The ranch became part of the Voorhis unit of what was then known as the California Polytechnic State College in San Luis Obispo.

[8] Today the facility is home to approximately 85 purebred Arabian horses used in Equine Sciences’ teachings, outreach, research and internationally recognized breeding and training programs.

Facilities at the center include 38 acres (150,000 m2) of pasture, three barns, foaling stalls, a breeding area, a veterinary clinic, a farrier shop, four arenas and a grandstand.
