Bison ranching on open Wyoming rangeland. Free-range, grass-fed, no antibiotics, no feedlots. We raise heritage bison the way they've grazed these plains for thousands of years.
Wyoming Bison
Bison are not cattle. They don't need barns, feedlots, or antibiotics. They thrive on open rangeland, grazing the native grasses that have sustained them for millennia. TEMBN Farms operates on Wyoming's open plains, raising free-range bison herds on thousands of acres of native grassland.
Our approach is simple: give the animals the space and the forage they evolved on, manage the land so it improves every year, and produce meat that is leaner, richer, and more sustainable than anything that comes out of a feedlot.

Our Operation
Our bison roam thousands of acres of native Wyoming grassland year-round. No confinement, no pens, no feedlots. They graze, they roam, they live as bison should.
We manage herd movement across pastures to prevent overgrazing, promote native grass recovery, and build topsoil. The land improves every year the herd is on it.
Our bison are never given antibiotics, growth hormones, or supplemental grain. Their diet is 100% native grass and forage — the way it's been for 10,000 years.
We maintain pure bison genetics without cattle hybridization. Heritage bloodlines produce animals with superior foraging instincts, hardiness, and meat quality.
Bison grazing restores native prairie ecosystems. Their hooves break up compacted soil, their grazing stimulates grass growth, and their movement spreads seeds across the range.
Field-harvested on the range to minimize stress. No transport to slaughterhouses, no feedlot finishing. The most humane and sustainable harvest method possible.
The Product
Grass-fed bison is leaner than beef, higher in protein, richer in omega-3 fatty acids, and lower in cholesterol. But the real difference is taste — deep, clean, and unmistakably better than anything grain-finished.

The Land
Wyoming is one of the last places in America where bison can live as they're meant to — on vast, unbroken rangeland under open sky. Our ranch sits on native shortgrass and mixed-grass prairie with natural water sources, seasonal creeks, and the kind of terrain that bison have grazed for thousands of years.
This isn't a hobby ranch or a petting zoo. This is a working operation on serious acreage, managed for the long term — the land, the herd, and the ecosystem all improving together.
