Primevac™ Herd health protocols by merck animal health

PrimeVAc, preconditioning programs for healthier, higher-value calves.


Proper preconditioning improves the efficiency and performance of calves, from the ranch to the feedyard. And that´s why PrimeVAC by Merck Animal Health gives you a marketing edge and the tools you need to make the most out of your cattle investment. This is the first program of its kind to offer optional veterinarian certification (or producer affidavit).


PrimeVAC focuses on three essential categories of protection:


  • Respiratory viruses and bacteria
  • Clostridial bacteria
  • Internal parasites

PrimeVAC also includes optional implant protocols.


You can count on PrimeVAC preconditioning programs for healthier, higher-value calves that help you take advantage of value-added premiums.
