Grade
Grade European bison is a ranch or inventory term for a wisent-type animal that lacks full registration, complete pedigree, or confirmed conservation status. It is not a formal breed. A grade animal may be pure European bison, partly crossbred, or simply undocumented, and outward appearance is not enough to settle the question. Bison bonasus has a narrow founder history, so lineage matters more than in ordinary livestock classification.
Grade animals can be useful in private display or non-release herds where the goal is not conservation breeding, but the limits should be clear to buyers and caretakers. DNA testing, microchip records, source documents, and veterinary paperwork help decide how the animal may be managed. Facilities must match the strength and behavior of a large wild bovid: substantial fencing, safe working pens, herd companionship, roughage-based feeding, and a plan for bulls, calving, and winter feed.
