In 1948, the ranch was transferred to the U.S. Department of Agriculture; and in 1949, the land was deeded to the W. K. Kellogg Foundation. Later in 1949, title to the then ranch and horses was passed to the State of California, with the provision that the herd of Arabian horses must be maintained. The ranch became part of the Voorhis unit of what was then known as the California Polytechnic State College in San Luis Obispo. This became known as the Kellogg Campus, and in 1966, it was separated to form California State Polytechnic College, Kellogg-Voorhis.
