Preston Bonine

Preston Bonine is a Chianina cattle breeder in Beresford, SD, Union County and the rolling hills of southeast South Dakota near Sioux Falls. He has been raising Chianina for over a decade and adheres to American Chianina Association health-testing guidelines for genetic soundness, including DNA profiling and disease screening.

His cattle graze on well-managed pastures that are rotated seasonally to support soil health and deliver high-quality forage. Comfortable shelters with ample bedding are available throughout the year, maintaining a stable environment across temperature extremes. Calves are handled daily from birth to encourage calm temperaments and facilitate smooth integration into herd management practices.

The breeding program emphasizes balanced structure, steady weight gain and strong maternal traits rooted in generations of selection. Record keeping tracks individual growth rates, with several offspring recognized at regional livestock shows for their consistent performance. Operated as a family-run enterprise, the farm combines traditional husbandry with data-driven decisions to sustain long-term herd vitality.
