James Jacobi

James Jacobi is a Chianina cattle breeder in Rohnert Park, CA, Sonoma County and the Bay Area near San Francisco. He has been breeding under American Chianina Association guidelines for over twelve years and carries out annual health screening for key bloodlines, fertility, and occasional mentorship of new breeders. His herd grazes on diverse pasture mixes with year-round access to shade, fresh water, and mineral supplements.

Calves are weaned using low-stress protocols on pasture and receive daily handling to build trust and confidence. Animals are fed a balanced diet formulated with local grains and forage to support steady growth and healthy finishing. The Jacobi family land has supported livestock since the early 1900s, and a recent review highlighted the herd’s calm demeanor and consistent build. An entry sired by one of his bulls earned recognition at the Sonoma County Fair, reflecting his steady breeding program.
