O'silvan Farm

O'silvan Farm, heritage shorthorn cattle, Rice, WA, is located in Adams County and the Columbia Basin near Moses Lake. Tamara Beltz has been breeding heritage shorthorn cattle for over a decade with the American Shorthorn Association, and the herd undergoes routine health screenings as recommended by veterinary guidelines. Each animal enjoys ample pasture access and open shelter year-round, supported by a tailored mineral program that meets seasonal nutritional needs.

Calves are handled from birth to build calm temperaments and strong social bonds within the herd. The farm began as a small homestead project and now uses rotational grazing on irrigated fields to promote both animal welfare and soil health. Heritage shorthorn cattle at O'silvan Farm display traditional color patterns and structural soundness that reflect the breed’s historic resilience. Emphasis on climate-adapted selection and pasture management contributes to a low-stress environment and productive, balanced animals.
