This free webinar, Wild Equid Management – The Role of Fertility Control, was presented by The Botstiber Institute for Wildlife Fertility Control. The webinar covered the challenges associated with managing wild horses and burros on our public lands and the role that fertility control could play in managing the herds in a more effective. When the American Wild Horse Campaign entered into agreement for the fertility control program in April , everyone knew there were already several babies born in the foal crop. This was due to many of the mares had been already bred back after having their foal.
PZP is a non-hormonal temporary fertility control vaccine that can be delivered via dart gun, or by “jab-stick” in the chute after capture to wild horses BLM intends to release. “PZP” currently comes in two forms; a 1-year dartable formula and a dose that has an added time release pellet that wears off in months (PZP). Even if Pendley and the BLM truly believe that wild horses, not cattle, are wreaking havoc across the West, the agency should be proactive in implementing safe, effective and humane fertility.
Darting wild horses with birth control. With a team of two dozen volunteers and a budget of $,, the American Wild Horse Campaign (AWHC) last year vaccinated more wild mares with fertility control than the Bureau of Land Management, with its $81 million-a . The most common fertility control vaccines for wild horses in use today are short-lasting and require near-annual treatment to remain effective, the agency says. The author of a new book.

Top Fertility control in wild horses: final report Item Preview remove-circle Share or Embed This : WASHINGTON – The Bureau of Land Management has started testing a promising new fertility control vaccine that could help address the growing overpopulation of wild horses on public rangelands.
Researchers believe the Oocyte Growth Factor (OGF) vaccine, administered to a captured wild mare through a single dose, may safely prevent pregnancy for up to three years or longer. The Center is a leader in fertility control research for wildlife.
As part of the project, 16 previously gathered wild mares were treated with the fertility control vaccine and will be placed in a pen with a stallion once the vaccine takes effect.
The Bureau of Land Management and partners will study the effectiveness of a fertility control vaccine that works in just one dose in feral horses previously removed from the wild. Last week, the BLM released an Environmental Assessment for the study, which they will conduct in partnership with the U.S.
Department of Agriculture Animal and Plant Health Inspection Service’s National Wildlife Research Center (NWRC). Fertility Control Porcine Zona Pellucida, or PZP, is a fertility-control vaccine given to female horses on the range through an injection via remote darting. PZP is scientifically proven, with over three decades of use, and is recommended by the National Academy of Sciences (NAS) for use in federally protected wild horse herds.
Thanks to PZP fertility control, the wild horse population in the Little Book Cliffs Wild Horse Range in Colorado, which has historically been subjected to roundups two to three years, has not been rounded up for seven years. PZP has also reduced population growth in the Pryor Mountains on the Montana/Wyoming border to historic lows.
Through Holmes’ documentation, photography, and PZP fertility control application, the wild horse population growth in Spring Creek Basin has slowed to the point where the BLM has no current plans. lUTTERWORTH |E l N E M A N N FERTILITY CONTROL USING INTRAUTERINE DEVICES: AN ALTERNATIVE FOR POPULATION CONTROL IN WILD HORSES P.F.

Immunocontraceptive vaccines that have been used for fertility control in wild horses in North America include the gonadotrophin releasing hormon ucida (PZP) vaccines. Walker is referring to an earlier agreement with the state that allowed the American Wild Horse Campaign to treat horses with fertility control.
It was canceled abruptly in after just a few years of implementation. The horses have run basically unmanaged since then. Veterinary applications of anti-fertility immunization can be used to control the reproduction of both domestic livestock and “pest” animals in the wild.
Damage to sensitive environments caused by the uncontrolled breeding of wild horses and elephants has been mitigated by vaccinating the females of these species with fertility antigens. The chosen method of fertility control — the PZP immunocontraceptive vaccine — creates an immune response that prevents fertilization without impacting the natural behaviors that make wild horses.
In national parks, treatment of a large number of wild horses over such a broad area would be challenging and impractical. (3) Fertility control for wild horses could be beneficial, but only if employed in conjunction with other broad-scale population-control practices to achieve population reduction and to minimise environmental impacts.
Just outside of Grand Junction, Colorado, we work closely with the Little Book Cliffs Wild Horse Range Fertility Control Darting Team to keep the Little Bookcliffs wild horse population at ideal levels. The volunteer advocates began working with the BLM in the early s.
Porcine Zona Pellucida. (PZP) is an immunocontraceptive that is used to control the reproductive rate of some mammalian species, including horses, deer and elephants. It has been in use since the ’s.
PZP is a vaccine derived from slaughterhouse pig ovaries (yes, we’d prefer this wasn’t the case). Since the passage of the Wild Free-Roaming Horses and Burros Act infederal agencies like the BLM are required to control any overpopulation of excess animals. Birth Control used on wild horses and burros is less understood by the public.
Discussions about birth control in wild herds has stemmed around the use of PZP, spayvac, gelding and recently at the Wild Horse and Burro Advisory Board meeting in the possibility of spaying wild mares was raised.
Although the committee’s report includes information on burros as well as horses, the need for fertility control in horses is considered more pressing because their populations are much larger (BLM,revised ). In addition, many more studies have focused on horses, so considerably more data are available on them than on burros.
The most common fertility control vaccines for wild horses in use today are short-lasting and require near-annual retreatment to remain effective. A single-dose vaccine that can last multiple years, such as the OGF vaccine if proven viable, would provide a number of benefits for BLM, including requiring fewer instances of gathering animals for.
Wild horse, burro program starts fertility control trials, sees adoption high. By Kaitlyn Mattson. Published on J Adoptions and sales of wild horses and burros through the Wild Horse and Burro Program have reached a year high, according to the Bureau of Land Management, which manages the program.

A. To decrease the number of wild horses and burros in overpopulated herd management areas, scientists with the Bureau of Land Management have begun testing a new fertility control drug.
