To Participate

1) Download the MCA Gold Vac 45/ Silver Vac Program Form.

2) Complete the form and return it to the MCA office.  Use our Example Vaccine Combinations as a guide for administering the correct vaccines.  

3) MCA will review the form to determine that it is complete, that the producer is an MCA member, and that the cattle are Silver Vac or Gold Vac 45 eligible. 

4) The form will then receive the appropriate approval designation and a copy will be sent back to the producer and to the auction market of destination.

On sale day, make sure your auctioneer announces groups of cattle that are MCA Gold Vac 45/ Silver Vac approved.  To help buyers recognize the MCA health protocol, we have provided each auction market with a rubber stamp of the MCA logo.  The auction market can use the logo on their sale catalog to indicate the groups of cattle that are MCA Gold Vac 45/ Silver Vac approved.

Goals of the MCA Gold Vac 45/ Silver Vac Program
