Rosenberger Ranch

Rosenberger Ranch is a Wagyu cattle breeder in Fairfield, CA, serving Solano County and the North Bay near Vallejo. The ranch has been raising premium Wagyu for over a decade under American Wagyu Association guidelines and maintains comprehensive genetic and health testing to ensure robust bloodlines. Owner Matthew Rosenberger follows a pasture-based husbandry approach, rotating herds across open grasslands to promote natural foraging behaviors and balanced nutrition.

Buyers have access to documented pedigrees and can observe daily operations by appointment. A recent review praised the ranch’s clear communication and consistent herd quality, reflecting a commitment to transparency and long-term animal welfare. The ranch participates in regional livestock exhibitions and shares sustainable cattle management insights with local schools and agricultural groups.
