David J. Mast

David J. Mast breeds Percherons in Opdyke, IL, in Southern Illinois near St. Louis. The Masts have been breeding Percherons for over a decade and are members of the American Percheron Horse Association. They prioritize health testing with routine veterinary evaluations and maintain detailed records to support sound breeding decisions.

Their horses live on rotational pasture grazing with access to loafing sheds, and they follow a regular farrier and nutrition schedule to promote sound hooves and balanced growth. Foals are handled daily from birth to build confidence around people, and older horses are exposed to varied environments to reinforce calm temperaments. The family farm blends regional draft horse traditions with modern welfare standards, reflecting a respect for both heritage and individual needs. Several of their Percherons have been showcased at regional fairs and involved in therapeutic riding demonstrations, highlighting the breed’s versatility and gentle disposition.
