VFD Calculator Mobile App

VFD Calculator app web header

Designed to assist veterinarians issuing a Veterinary Feed Directive (VFD) for beef cattle, the VFD Calculator App will calculate the appropriate drug concentrations in order to issue a VFD that will conform to label directions.

Once a veterinarian makes an appropriate therapeutic decision to administer a drug in cattle feed, the VFD app will help calculate the appropriate drug concentrations to enhance accurate communication among the veterinarian, cattle producer, and feed supplier.

The calculator app requires only a few pieces of information:

  • Class of cattle and the disease condition being treated
  • Drug to be administered in the feed
  • Daily feed intake

The app is designed so that only legal combinations of disease, cattle classification and drug are available for selection before it calculates the appropriate drug concentration in the feed. The calculated drug concentration is needed to complete the VFD.
