## What is UC Davis BRD?

The California (CA) BRD scoring system was developed by researchers at the University of California (UC) Davis’s School of Veterinary Medicine, Department of Animal Science and UC Agriculture and Natural Resources. This calf-side system relies on the binary classification of significant predictors of BRD in preweaned dairy calves based on a statistical model of over 2000 preweaned dairy calves. The system was also validated using data from over 500 preweaned dairy calves in California.

The app can be used as an aid to the herd veterinarian and producer in the prevention and control of pneumonia in pre-weaned dairy calves under the Veterinary Client Patient Relationship. Calves can be scored to determine their CA BRD score status and results stored in a searchable database on the user’s mobile device.
Users can also estimate the prevalence of BRD in a herd of calves by scoring a random sample of calves that the app identifies upon providing the herd size and the required inputs for a sample size formula or accepting the defaults for a best guess prevalence estimate (25%) and how tight of a 95% confidence interval is desired (10% bound). 
Similarly, the Spanish version is accessible once the device language is switched. 
Under settings, users can switch between Celsius and Fahrenheit temperature input and elect to email questions and results to the Veterinary Medicine Teaching and Research Center, UC Davis if that option is selected.
