What is SelectVAC®?

SelectVAC® is the beef industry’s No. 1 branded preconditioning program, combining cattle vaccination and management services to prepare calves for weaning and shipping. SelectVAC® helps deliver healthier cattle for buyers and greater profits for ranchers. Here’s what you can expect from SelectVAC®:

  • Healthy cattle. SelectVAC® calves are healthy, thanks to trusted Zoetis brands like BOVI-SHIELD GOLD®, BOVI-SHIELD GOLD ONE-SHOT®, CATTLEMASTER® GOLD, ONE SHOT®, ONE-SHOT® BVD, INFORCE™ 3, and DECTOMAX®.
    • Less illness. Calves enrolled in the WeanVAC™ program have been shown to be 4 times less likely to get sick than non-preconditioned cattle.1
    • Increased weight gain. WeanVAC™ calves gained 36 more pounds in the first 85 days.1
  • Greater profits. SelectVAC® calves earn more per head.
    • WeanVAC™-like calves earned an average of $35/head in auctions between 1995-20122
    • WeanVAC™ calves earned up to $72/head in auctions between 2014-20153
  • Flexible health designations. SelectVAC® offers 4 different vaccination program options to meet the needs of your operation and goals.
  • Advantages over other health programs. SelectVAC® has a solid record of performance since 1995, with millions of calves enrolled. Every SelectVAC® enrollment is validated by a third party prior to approval, so buyers are confident that they’re getting the quality livestock for which they paid.

“When you compare SelectVAC® calves with those that are not vaccinated, there’s a mile of difference in actual dollars. With WeanVAC™, they’re getting $20, $50, maybe $60 per head returns. With PreVAC™, where calves are coming off the cow, those cattle bring $20 more per head, easily.”
