Since DNA testing for purity has become available, there is a growing movement among bison ranchers to test their herds and cull animals that test positive for bovine DNA. The largest private herd in the world, with over 50,000 animals, is currently undergoing such a program. As similar programs gather momentum among smaller private herds, the level of hybridization among private herds will likely reduce to a very small level as there is no commercial gain to be had by hybridization and both the Canadian and American Bison Associations share the goal of preserving pure bison herds.{{cn|date=August 2022}} |

However, at present, most private herds have yet to be tested for bovine DNA and the majority of plains bison in North America can be found in these private herds. As these herds have been built from the same original base stock as the public herds, is possible that up to 6% of some herds may contain bovine DNA. Consequently, out of approximately 500,000 bison in North America, it is possible that up to 30,000 may have some bovine DNA. Due to many base herds having started pure with feed stock from pure public herds such as Elk Island Park, this may be a high estimate and the true number of bison containing bovine DNA is likely to be significantly lower.{{cn|date=August 2022}} |
