Three Things to Know About PZP

The following is from the American Wild Horse Campaign:

We’ve almost made it to the end of October!

Let’s talk about PZP, scientifically known as the Porcine Zona Pellucida vaccine, a proven-safe and effective fertility control tool for managing wild herds. PZP is the humane, in-the-wild conservation alternative to cruel, costly federal helicopter roundups. Even better? One dose of PZP costs only about $30.

Will you help us celebrate the 30th of October with a gift of $30 to cover the cost to keep one wild mare and her family in the wild where they belong?

As an advocate for our wild herds, here are three important facts you should know about this game-changing conservation method:

1. PZP is safe. The PZP vaccine has a 90-95% efficacy rate without disrupting mares’ natural hormonal cycles — keeping them wild and free on the range, where they belong. Plus, the PZP vaccine can be administered through darts, eliminating the justification for brutal roundup operations.
2. PZP is cost-effective. A lifetime of fertility control using PZP for a mare costs about $1,350 — compared to the staggering $48,000 it costs to keep one horse in government holding for life.
3. We’re proving it every day. Since 2019, our program in Nevada’s Virginia Range has seen a 72% decline in foal births, stabilizing this population in areas where development is encroaching on the mustang’s habitat. It’s the largest fertility control program in the world for wild horses, supported by a community-based effort involving local and state partners.

Together, we can keep wild horses and burros wild. 

By donating $30 today, you can help cover the cost of one PZP dose, directly contributing to the long-term solution for keeping wild horses safe, free, and wild. This October 30, make a difference for America’s wild horses by supporting a humane, lasting solution.

Thank you for standing with us in defense of these iconic animals.
