The Bovine Respiratory Disease (BRD) risk assessment tool for preweaned calves on dairies relies on scores that are proportional to the association measures observed between management risk factors and BRD. The scores were based on data sets including over 11,000 calves on 5 dairies and more than 4,500 calves on 100 dairies. Together with the California BRD scoring system for preweaned calves, producers, veterinarians and consultants can use this BRD risk assessment tool to objectively monitor BRD prevalence and adjust management factors that are dairy specific and that may be most important contributors to the risk for BRD in their calf herd. The methods of determining the risk of bovine respiratory disease (BRD) in preweaned dairy calves on a dairy farm are patent pending, 2018 The Regents of the University of California.
