MAC-Vac Program

The MAC-Vac team is excited to start this program and bring our customers this new opportunity. Any size operation at any time during the year can utilize this program. Contact us for more information!

What is it?

A marketing tag program that will recognize calves that have been vaccinated and pre-conditioned. Calves must meet minimum vaccination requirements and will qualify for a MAC-Vac ear tag to be sold during the MAC-Vac portion of our sales. The program allows for greater flexibility for our producers allowing them to market value-added cattle at any of our weekly sales. 

How does it work?

Tagged calves with a completed health documentation form can be brought into any of our weekly sales. Calves will be penned separately from the regular sale calves. All MAC-Vac calves that are brought in by 12 noon on sale day will sell at the beginning of the feeder calf portion of the regular weekly sales. Cattle will be sold as singles or grouped by producer. This program allows buyers to purchase verified vaccinated calves and producers to receive increased marketing on their calves and sell at the beginning of the sale each week.


A flexible program to help you receive premiums for vaccinating and preconditioning your cattle. This program allows you to sell your cattle at any time, not just certain sales during the year. It also does not require a certain brand of products, just that you meet minimum vaccine requirements. This program also allows for all sizes of producers to be able to participate.


• Steers and Heifers only, bull calves do not qualify

• Minimum required vaccines given within 90 days of being sold and at least 21 days prior to being sold.
