Johnny Mast

Johnny Mast and Toby Mast breed Percheron horses in Opdyke, IL, in Jefferson County and Southern Illinois near St. Louis. They have been part of national breeding associations for more than a decade and follow thorough health testing protocols, including annual hoof evaluations and equine metabolic screenings.

Foals grow up in pasture-based herds, receive daily handling from early weeks and are regularly exposed to farm machinery sounds for calm temperaments. The stable itself features roomy stalls with straw bedding and offers turnout in spacious paddocks shaded by oak trees.

Many of their horses have competed successfully at local agricultural fairs, earning ribbon placements in draft horse classes. Visitors note the approachable demeanor of both adults and foals, praising the Masts’ quiet confidence and consistent routines. Farm visitors appreciate seeing daily care routines and meeting the team behind the herd. Seasonal foaling typically occurs in spring.
