A recent survey by dairy scientists at the University of Wisconsin found that producers in the state with large herds (more than 200 lactating cows) adopted more biosecurity practices than those with small herds.

They also found that biosecurity risks are common, regardless of herd size. For example, only 49 percent of the responders who purchase cattle perform diagnostic tests on those cattle.

The survey results were reported in the Journal of Dairy Science last June. To read the abstract, follow this link
