On-farm cost calculator to demonstrate impact of subclinical disease

This tool was built in R Shiny and is designed to help farmers and rural health professionals identify the sub-clinical cost of facial eczema (FE) on the farm due to milk production and body condition score loss.

To build the application we worked closely with veterinarians from VetEnt Research to help link outputs from a research study on Facial Eczema (FE) with on-farm stakeholders to support awareness of the impact of a subclinical disease.

The calculator allows user to select different levels of FE extent in herds of different sizes to understand the disease’s effect on milk production and live weight.  Feed and milk values (such as $kg milk solids) can be adjusted past the default values, if desired, and assumptions are displayed alongside the calculations.

Since apps for on-farm use are mainly accessed from mobile devices we designed the app so that it would easy format to a mobile screen.
