Health Canada has given the green light for a birth control vaccine trial on free-roaming horses in Alberta, following concerns about escalating horse populations impacting grazing areas. The Alberta government views contraception as a vital tool for managing wild horse numbers, alongside strategies like removal and adoption. A “research authorization” was granted for the use of the contraceptive vaccine SpayVac-Equid, with ongoing evaluation of the approval specifics underway.
Recent surveys revealed a record 2,072 wild horses in Alberta’s equine management zones, with certain areas deemed unsustainable due to population levels. An earlier contraception pilot project in 2014 tested a different vaccine called ZonaStat-H, highlighting challenges such as high costs and terrain difficulties. The new approach involves capturing horses, administering the vaccine manually, and releasing them marked back into the wild, aiming for long-term contraception without altering herd dynamics.
The Wild Horses of Alberta Society aims to implement this new strategy, which includes capturing select young stallions for population control. The goal is to balance the needs of various land users while maintaining wild horse populations and ensuring their welfare. The society’s efforts in rescuing, rehabilitating, and rehoming horses align with their commitment to preserving these iconic animals.
