According to the National Animal Health Monitoring System’s Dairy 2007 study, only 23 percent of dairies required any disease testing prior to introducing new cattle to the operation. “In addition, nearly 30 percent of producers said Johne’s disease, bovine viral diarrhea or contagious mastitis were not a concern to their operation,” says Jason Lombard, NAHMS dairy specialist. “It looks as though biosecurity practices aren’t being adopted as frequently as we would like,” he says. Producer concern about testing costs, inconsistent messages on what are appropriate biosecurity measures and the scope of biosecurity management practices are possible explanations. However, Lombard says a focus on preventing disease introduction and the performance of on-farm risk assessments are good places to start.
