Donati Family

Donati Ranch is located in the northern part of Sacramento Valley and is a family-run operation. Founders Tom and Sally Donati grew up in commercial beef cattle production and are both graduates of the agriculture program at Cal Poly San Luis Obispo.

Donati Ranch started with a commercial herd and continued to strive to improve the performance and carcass merit of the feeder cattle they were selling by participating in the Young Sire Evaluation Program in cooperation with the American Angus Association.

The purebred herd was begun in the early 1990s as a 4-H project for Sally and Tom's two sons Rocky and Chris. Originally the registered Angus bull calves were used in the Donati Ranch commercial herd. As the purebred herd continued to grow, the ranch began marketing bulls to other commercial producers in private treaty and consignment sales.

Since 2000, the bulls have been marketed in cooperation with other like-minded purebred breeders in the Black Gold Bull Sale that is held the second Thursday in September in Colusa, California. Rocky and his wife Lisa, also both graduates of Cal Poly SLO, are a significant part of the cattle operation. Their children, the next generation, Nico, Gemma, and Leo all help as they can.

The Donati family takes pride in selecting cattle based on industry factors that drive profitability in the commercial sector. Calving ease, maternal traits and growth are the cornerstone of a profitable commercial cattle operation. Those traits coupled with selection for carcass merit, means that Donati Ranch bulls offer a complete package for commercial ranches.

The Donatis take pride in being a family-run operation that earns its livelihood in production agriculture.
