Vaccinations are an extremely important component of any herd health program. The optimal program, including type of vaccines and frequency of administration, will depend on operational-specific factors including cattle genetics, calving season, and location. Marketing cattle using Western Video Market (WVM) Auction allows ranchers the flexibility to list all of the vaccinations given to each lot including type (e.g., 8-way, Bovi-Shield Gold, etc.), brand (e.g., Zoetis, Merck), and frequency and timing (e.g., at branding, 2 weeks prior to shipment, etc.).
