The foundation herd of Gleason Bison is comprised of Wind Cave, Yellowstone, and Charles Goodnight herd genetics. Through genetic testing we can confirm that the entire herd does not carry any cattle genes. Our bison are 100% grassfed their entire lives and are harvested stress-free in the field on their home land.
At Gleason Bison, we are committed to positively impacting the bison species and the conservation ranching necessary to increase the American Bison population. Providing the highest quality nutrition possible and practicing a strong culling program results in high breeding and calving rates, healthy and beautiful animals, and the best bison genetics.
