Braunvieh is not a crossbreed, or a new breed developed using two or more breeds. On the contrary, Braunvieh may be the oldest pure breed on Earth, with records dating back to 800 B.C. Recently, archeologists have found cattle bones among the ruins of the ancient Swiss Lake Dwellers similar to those of the present day Braunvieh. This would date these cattle in the region to the Bronze Age.
