Diamond D Angus

Diamond D Angus raises Angus cattle in Valier, MT, in Pondera County near Great Falls. Mark Deboo has been raising Angus cattle for several years as a member of national cattle organizations, and his herd undergoes regular health testing under veterinary guidance to promote strong genetics.

The cattle graze on open grasslands during the warmer months and shelter in well-ventilated barns through winter, receiving balanced nutrition from locally sourced hay and grains. Daily handling routines and early socialization help develop calm temperaments and ease management. Each animal benefits from individual attention during calving season and routine hoof care to support lifelong well-being.

The farm combines time-honored ranching methods with thoughtful land stewardship, rotating pastures to preserve soil health and biodiversity. Visiting ranchers and local customers often comment on the herd’s steady dispositions and the transparent updates provided on herd performance. This ongoing focus on animal welfare and open farming practices reflects the ranch’s steady commitment to responsible cattle breeding.
